BIO-INSPIRED FLAPPING-WING AERODYNAMICS OF MICRO AERIAL VEHICLES (MAVs)

 

In this research we are developing advanced space-time computational techniques for bio-inspired flapping-wing aerodynamics of micro aerial vehicles (MAVs). The wing motion and deformation patterns, whether prescribed fully or partially, are based on digital data extracted from the high-speed, multi-camera video recordings of a locust in a wind tunnel. The computational techniques we are developing include space-time representation of the wings with higher-order basis functions in time. This higher-order representation in time gives us good accuracy and smoothness in wing motion and deformation patterns. Our objectives in this research include design of flapping MAV wings with wing motion and deformation patterns inspired by those of a locust or other flying animals. We are also working on the fluid-structure interaction (FSI) analysis of this class of problems.

THERMO-FLUID ANALYSIS OF GROUND FREIGHT VEHICLES

 

In this research we focus on thermo-fluid analysis of a ground freight vehicle and its tires, currently the rear tires. The analysis is challenging because the flow is turbulent, there is interaction between the fluid mechanics and thermal transport, the truck model used in the analysis closely represents the actual configuration, and we need accurate thermal analysis around the tire, which is significantly smaller than the truck. All this requires a method that is multiscale in multiple aspects. We address the computational challenges with the core and special multiscale space-time (ST) methods we developed. The core multiscale ST method is the ST variational multiscale (ST-VMS) formulation of the Navier-Stokes equations of incompressible flows with thermal coupling, which is multiscale in the way the small-scale thermo-fluid behavior is represented in the computations. The special multiscale ST method is spatially multiscale, where the thermo-fluid computation over the global domain with a reasonable mesh refinement is followed by a higher-resolution computation over the local domain containing the rear set of tires, with the boundary and initial conditions coming from the data computed over the global domain. The large amount of time-history data from the global computation is stored using the ST computation technique with continuous representation in time (ST-C), which serves as a data compression technique in this context. In our thermo-fluid analysis, we use a road-surface temperature higher than the free-stream temperature, and a tire-surface temperature that is even higher. We include in the analysis also the heat from the engine and exhaust system, with a reasonably realistic representation of the rate by which that heat transfer takes place as well as the surface geometry of the engine and exhaust system over which the heat transfer occurs. We take into account the heave motion of the truck body. We demonstrate how the spatially multiscale ST method, with higher-refinement mesh in the local domain, substantially increases the accuracy of the computed heat transfer rates from the tires.

COMPUTER MODELING OF SPACECRAFT PARACHUTES

 

In this research we focus on fluid-structure interaction (FSI) modeling of spacecraft parachutes. The geometric complexity created by the "rings" and "sails" used in the construction of these parachutes poses a significant computational challenge. Our FSI modeling of these parachutes is based on the stabilized space-time FSI (SSTFSI) technique we have developed and a number of interface projection techniques we introduced. These projection techniques address the computational challenges posed by the geometric complexities of the fluid-structure interface. The spacecraft parachutes are typically used in clusters of two or three parachutes. The contact between the parachutes is another major computational challenge, and we are addressing that with a special contact method we have developed. Spacecraft parachutes are also typically used in multiple stages, starting with a "reefed" stage where a cable along the parachute skirt constrains the diameter to be less than the diameter in the subsequent stage. After a certain period of time during the descent, the cable is cut and the parachute "disreefs" (i.e. expands) to the next stage. Computing the parachute shape at the reefed stage and FSI modeling during the disreefing involve additional computational challenges created by the increased geometric complexities and by the rapid changes in the parachute geometry. We are addressing those challenges. As an additional computational challenge, the ringsail parachute canopy might, by design, have some of its panels and sails removed. The purpose is to increase the aerodynamic performance of the parachute.  In FSI computation of parachutes with such "modified geometric porosity," the flow through the "windows" created by the removal of the panels and the wider gaps created by the removal of the sails needs to be actually resolved, and we addressing that computational challenge.

PATIENT-SPECIFIC COMPUTER MODELING OF ARTERIAL DYNAMICS AND BLOOD FLOW

 

We are developing advanced computational techniques for patient-specific computer modeling of arterial dynamics and blood flow and the interaction between the two. Our studies include blood flow in cerebral arteries with aneurysm, human aorta, coronary arteries and heart valve models. Our objective is to make patient-specific computer modeling of arterial dynamics and blood flow a medical diagnostic and decision-making tool that can save lives. We are addressing the main computational challenge involved: fluid-structure interaction (FSI) between the blood flow and arterial walls. The blood flow depends on the arterial geometry, and the deformation of the arterial wall depends on the blood flow. The equations governing the blood flow and arterial deformation need to be solved simultaneously, with proper kinematic and dynamic conditions coupling the two physical systems. Without that the modeling cannot be realistic. While modeling the FSI between the blood flow and arterial walls is one of the most challenging problems in cardiovascular fluid mechanics, there are other complex problems that are comparably challenging. Patient-specific computation of unsteady blood flow in an artery with aneurysm and stent is one of them. Blood flow in heart valve models and coronary arteries are two other examples. We are addressing those computational challenges.

AERODYNAMIC ANALYSIS OF WIND TURBINES

 

Aerodynamic analysis of wind turbines is challenging because the rotor geometry is rather complex, and the analysis is done at full scale. The computation is challenging also because of the large Reynolds numbers and rotating turbulent flows, and computing the correct torque requires an accurate and meticulous numerical approach. The presence of the tower increases the computational challenge because of the fast, rotational relative motion between the rotor and tower. The core computational technology used in the analysis is the space-time variational multiscale (ST-VMS), which our team developed. The VMS component of this method addresses the turbulent nature of the computational challenge. In our analysis, NURBS basis functions are used for the temporal representation of the rotor motion, enabling us to represent the circular paths associated with that motion exactly and specify a constant angular velocity corresponding to the invariant speeds along those paths. In addition, temporal NURBS basis functions are used in representation of the motion and deformation of the volume meshes computed and also in remeshing. This increases the robustness and accuracy the computations with mesh motion.

THERMO-FLUID ANALYSIS OF A DISK BRAKE

 

In this research we focus on thermo-fluid analysis of a disk brake, including thermo-fluid analysis of the flow around the brake and heat conduction analysis of the disk. The computational challenges include proper representation of the small-scale thermo-fluid behavior, high-resolution representation of the thermo-fluid boundary layers near the spinning solid surfaces, and bringing the heat transfer coefficient (HTC) calculated in the thermo-fluid analysis of the flow to the heat conduction analysis of the spinning disk. The disk brake model used in the analysis closely represents the actual configuration, and this adds to the computational challenges. The components of the method we have developed for computational analysis of the class of problems with these types of challenges include the Space-Time Variational Multiscale (ST-VMS) method for coupled incompressible flow and thermal transport, ST Slip Interface (ST-SI) method for high-resolution representation of the thermo-fluid boundary layers near spinning solid surfaces, and a set of projection methods for different parts of the disk to bring the HTC calculated in the thermo-fluid analysis. With the HTC coming from the thermo-fluid analysis of the flow around the brake, we do the heat conduction analysis of the disk, from the start of the breaking until the disk spinning stops, demonstrating how the method developed works in computational analysis of this complex and challenging problem.
