## 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

## 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
