Dear friends, I am a beginner in CFD.. I want to write a code to compute the flow over a blunt nosed body.Flow is being hypersonic. I would like to use Matlab / C. Which one will be better if I have to finish my work within 25 days?? C, I know.. Matlab-beginner..

First of all I want to know,what should be my first move.

Plz help...

Regards, Student

Hi, For writing the code first of all you should formulate the governing equations which your are going to solve through cfd and use some simple techniques for solving the governing equations.I prefer matlab for writing the code because it is some what user-friendly compared to C language.

Hope this will serve your purpose for initializing the problem

Regards, Srinivas

Thanks Srinivas and friends.. But, How can I take care of turbulence?? May I neglect viscosity terms (since it is hypersonic flow problem).. Which book should I read to know about these things?? Kindly suggest..

Regards, VVJ

Hello,

For supersonic case you could use the inviscid form of the conservation equation (the Euler equations), I'm not sure about hypersonic ...

In my experience trying to develop a simulation code in Matlab is cumbersome (very poor programming environment and low execution speed - Matlab is an interpreted language), if you know C than this is the way.

If you want references:

- for the basic equations:

1. Anderson - Fundamentals of Aerodynamics.

2. Hirsch - Numerical Computation of Internal and External Flows.

- for numerical methods:

1. Blazeck - Computational Fluid Dynamics.

2. Hirsch - Numerical Computation of Internal and External Flows.

3. Frink, Neal T. - Upwind scheme for solving the Euler equations on unstructured tetrahedral meshes

- open source codes:

OpenFoam - language C++

nsc2ke - language FORTRAN

To finish your work in 25 days forget about finite volume method and solving Navier-Stokes or Euler equations You can make a panel code based on modified Newton theory (i.e. pressure coefficient depends upon angle between the flow and the panel normal). For Ma>5 it has pretty good accuracy
