Numerical computation of two dimensional viscous blunt body flows with an impinging shock. (). Numerical simulation of reacting flows related to the HEG. This paper investigated the spiked blunt bodies with and without sideward jets flying at hypersonic speed, using numerical simulations. The incoming flow Mach number changed from 5 to 10, and the spike length ratio over the blunt body diameter changed from to I am trying to do a hypersonic flow simulation over a spiked blunt body at mach 6 using fluent In my case, I use first order upwind scheme and get a very well converged solution. however, when I switch to second order upwind scheme, totally diverge Any one has some suggestion to .

Hypersonic flow can be approximately separated into a number of regimes. The selection of these regimes is rough, due to the blurring of the boundaries where a particular effect can be found. Perfect gas. In this regime, the gas can be regarded as an ideal gas. Flow in . T1 - Numerical study of hypersonic boundary layer transition on a blunt body. AU - Johnson, Heath B.

N2 - Highly resolved solutions of the flow over both sharp cone and blunt-nosed hypersonic bodies are found using computational fluid by: 5. Welcome to the hypersonic CFD group at IIT Bombay. We are an interesting collection of graduate and undergraduate students synergistically working together at the frontiers of research. Our primary interest is to study high-speed flows in aerospace applications. realized in the broad, stagnation region of blunt bodies where system eigenvalues are small. Nevertheless, computational aerothermo-dynamic tools that generally do a good job in handling the difficulties of steady, laminar, hypersonic, blunt body and attached flow simulation have evolved over the past 15 years. The greatest.

Hypersonic nonequilibrium flow simulations over a blunt body using bgk simulations. View/ Open. (Mb) a lot of focus has been given on research pertaining to numerical approach to understand this physics. The features of such flows are quite different from those of subsonic, transonic and supersonic ones and thus normal. *****.Excerpt from Numerical Computation of Hypersonic Flow Past a Two-Dimensional Blunt Body Given a two-dimensional blunt body in a steady supersonic flow of compressible fluid, the problem is to study the flow between the body and the detached shock wave formed in front of it.
