## Establishing Grid Convergence

Establishing grid convergence is a necessity in any numerical study. It is essential to verify that the equations are being solved correctly and that the solution is insensitive to the grid … Continue Reading Establishing Grid Convergence

## The Ahmed Body

The Ahmed body is a geometric shape first proposed by Ahmed and Ramm in 1984. The shape provides a model to study geometric effects on the wakes of ground vehicles … Continue Reading The Ahmed Body

## Shocktube – rhoCentralFoam TVD Schemes Test

Careful selection of TVD interpolation schemes is important for solving high speed compressible flows. In cases with discontinuities such as shockwaves and contact surfaces, these schemes help keep the simulations free of … Continue Reading Shocktube – rhoCentralFoam TVD Schemes Test

## Couette Flow (Moving Wall)

In this post I am going to go through the solution to the moving wall Couette flow problem. An illustration of the problem is given below: In this problem, the fluid … Continue Reading Couette Flow (Moving Wall)

## Definition of the Speed of Sound

Deriving the speed of sound is a main component of any undergraduate textbook in gas dynamics and is very important to understanding more complicated concepts! Here, I will give an honest … Continue Reading Definition of the Speed of Sound

## Derivation of the Euler Equations

In this post I am going to derive the compressible Euler equations: (1) (2) (3)

## Oblique Shockwaves

In this post I go over the theory of oblique shocks by building on our understand of normal shockwaves! I will give a short overview of the theory and strategy … Continue Reading Oblique Shockwaves

## Mach 1.5 flow over 23 degree wedge – rhoCentralFoam

In this post I will simulate inviscid Mach 1.5 flow over a 23 degree wedge of a finite height.

## Compressible Aerodynamics Calculator – Matlab

Here I have written a Matlab App for calculating compressible aerodynamics using the basic gas dynamics equations. The calculations available are: Isentropic Flow (including Prandtl-Meyer flow) Normal Shocks (See article) … Continue Reading Compressible Aerodynamics Calculator – Matlab
