Research Interests
Numerical analysis.
Computational fluid dynamics and shocked flow.
Numerical solution for partial differential
equations.
High performance scientific computing.
High order shock capturing schemes for the
discontinuous solution of nonlinear hyperbolic conservation laws:
Spectral methods; and
High order conservative finite difference WENO-Z
scheme.
Hybridization of the spectral methods, high
order WENO methods and high order central difference schemes along with the
high order Multi-resolution algorithm under a single- and multi- domain
framework.
This is
a joint work with Prof. David Gottlieb
(
Supersonic combustion for recessed cavity in a
scramjet engine.
This is
a joint work with Prof. Jae-Hun Jung (U.
Mass at
Shock-Particle-Laden-Flow.
This is a joint work with Prof. Gustaaf Jacobs
(
Preliminary simulations: Mach 3 shock
with 40K bronze particle clouds: Vorticity and Density.
A snap
shot of density, vorticity and particle
trajectory can be viewed here.
Large scale numerical simulations of
single-mode/multi-modes multi-dimensional Richtmyer-Meskov
Instability (RMI) and Rayleigh-Taylor Instability (RTI) via spectral methods
and/or high order conservative WENO finite difference schemes.
This is a joint work with Prof. David Gottlieb
(
Software development of the PseudoPack
library which
Perform optimized and efficient pseudospectral differentiation for the
Fourier, Chebyshev and Legendre collocation methods along with other algorithmic enchancements;
High Order WENO Flux Reconstruction with
enhancement are available for the Scalar and Euler system;
Parallelization based on the MPI and the OpenMP is enabled; and
Many other useful utility routines.
This is a joint work with Dr. Alex Solomonoff and Prof. Bruno Costa.
