A positivity-preserving high-order weighted compact nonlinear scheme for compressible gas-liquid flows
Man Long Wong, Jordan B. Angel, Michael F. Barad +1
We present a robust, highly accurate, and efficient positivity- and boundedness-preserving diffuse interface method for the simulations of compressible gas-liquid two-phase flows w…
Turbulence Enrichment using Physics-informed Generative Adversarial Networks
Akshay Subramaniam, Man Long Wong, Raunak D Borker +2
Generative Adversarial Networks (GANs) have been widely used for generating photo-realistic images. A variant of GANs called super-resolution GAN (SRGAN) has already been used succ…
Homogenized Flux-Body Force Treatment of Compressible Viscous Porous Wall Boundary Conditions
Daniel Z. Huang, Man Long Wong, Sanjiva K. Lele +1
A homogenization approach is proposed for the treatment of porous wall boundary conditions in the computation of compressible viscous flows. Like any other homogenization approach,…
High-resolution Navier-Stokes simulations of Richtmyer-Meshkov instability with re-shock
Man Long Wong, Daniel Livescu, Sanjiva K. Lele
The interaction of a Mach 1.45 shock wave with a perturbed planar interface between sulphur hexafluoride and air is studied through high-resolution two-dimensional (2D) and three-d…
A High-Order Weighted Compact High Resolution Scheme with Boundary Closures for Compressible Turbulent Flows with Shocks
A. Subramaniam, M. L. Wong, S. K. Lele
We present an improved high-order weighted compact high resolution (WCHR) scheme that extends the idea of weighted compact nonlinear schemes (WCNS's) using nonlinear interpolations…
