Fluid Dynamics (CFD)
Numerical methods for the solution of Euler and Navier-Stokes equations, in
particular the kinetic schemes and the vorticity confinement method. Convergence
acceleration techniques. Turbulence modeling. Parallel computing.
- Flow Control
Numerical study of the influence of synthetic jets on drag reduction
by separation control in transonic flow and on vectoring control of a propulsive
jet. [ in collaboration with Dr. William Bower and Dr. Andrew Cary of Boeing
Application of robust H-infinity control theory to study the control of transition
in complex (polymer) fluid flows. [in collaboration with Professor Sureshkumar
of the Chemical Engineering Department]
Flow control with the application of a magnetic field.
- Flows in Continuum-Transition
Development and application of higher-order continuum equations
of fluid dynamics, namely the Burnett equations, to compute the flows at moderate
Knudsen numbers which occur in hypersonic regime at high altitudes as well
as in microdevices.
Development of 2-D and 3-D electro-magneto-hydrodynamics codes to evaluate
the concepts of supersonic drag reduction and by-pass propulsion for scramjets.
Development and application of explicit and implicit kinetic schemes, vorticity
confinement methods and turbulence models for MHD flows, MHD flow control.
Solution of acoustics equations (Euler equations linearized about
the mean flow) using compact higher-order schemes. Novel farfield boundary
conditions. Applications to acoustic scattering, propagation and radiation
Development and application of Discontinuous Galerkin (DG) method
for the solution of Maxwell equations to compute the electromagnetic scattering
from complex objects. Formulation of novel farfield radiation condition and
material surface boundary conditions.
Analysis Using Neural Networks
Application of Artificial Neural Networks (ANN) to achieve very
fast convergence of fluid dynamics and structures codes to obtain aeroelastic
loads on aircraft components such as wing, fuselage, tail, etc.
- Control Theory
and Applications to Flight Control
Linear and nonlinear robust control of uncertain systems, nonlinear
adaptive control, reduced-order modeling, singular perturbation method, applications
to aircraft control under adverse weather conditions, to aircraft landing
system and to control of an aeroelastic aircraft. [in collaboration with Dr.
Rolf Rysdyke of the University of Washington, Dr. Peng Shi of DSTO, Australia
and Prof. M. Mahmoud of the Arab Academy of Science and Technology, Egypt]
- Aortic Stenosis
Theoretical and computational study of valvular or vascular stenosis.
One of the goals of the study is to provide hemodynamic assessment of valvular
stenosis by computationally determining the range of applicability of frequently
used Gorlin's formula (and its improved versions) by the cardiologists to
relate the cardiac output to the aortic valve area. [ in collaboration with
Professor R.D. Rifkin, Dr. M. Wendel, and Dr. D. Dooling of the School of
