Numerical simulations of hypersonic magnetohydrodynamics (MHD) flow over a typical sphere–cone blunt body are carried out based on the assumption low magnetic Reynolds number. The effects an external dipole field surface heat flux analyzed in detail, and multiple mechanisms MHD mitigation revealed systematically for first time. following is found: (1) can effectively reduce stagnation point flu...

Hyper2D is a finite-volume solver for hyperbolic partial differential equations (PDEs) and non-equilibrium flows. Its minimalistic structure makes quickly adaptable to one’s needs. Non-standard systems of source terms are easily implemented by modifying single pde file. In our research, we use studying rarefied hypersonic gas dynamic problems (moment methods), relativistic flows, multi-fluid pl...

This paper examines the use of a hypersonic bi-directional flying wing concept for use in a high efficiency hypersonic system. The bi-directional flying wing concept consists of a symmetric planform which enables flight to occur at two different geometric configurations. The subsonic configuration would have a high aspect ratio and a low sweep. The aircraft would then rotate 90 degrees and ente...

Computer simulations have been an effective tool to study transient flow processes in hypersonic flow and have been complementing experimental and theoretical studies to better understand the flow transition process. There have been lots of efforts in code development for high order simulation of nonequilibrium flow but most of the methods are based on shock capturing ideodology. Shock capturin...

Gold nanodisk arrays on the upper surface of GaN nanorods were developed with the aim of achieving hypersonic imaging with a detection frequency above 10GHz. In this talk, we report the interesting phenomenon that the hypersonic signal detected by a single gold nanodisk in this structure is dependent on the array periodicity and rod length. We not only investigate the transport behavior of hype...
