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

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.
