The equations used to describe steady 1D isentropic flow are derived from conservation of mass, momentum, and energy, as well as an equation of state (typically the ideal gas law). … Continue Reading Equations for Steady 1D Isentropic Flow

An excellent test case, and case to familiarize yourself with some of the turbulence models available in OpenFOAM is a 2D flat plate with zero pressure gradient. I will solve … Continue Reading Turbulent Zero Pressure Gradient Flat Plate – simpleFOAM, komegaSST

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

I was recently asked by a class to go over the Newton-Raphson method for solving non-linear equations. Specifically in this case it was to solve 1D gas dynamics equations. Here … Continue Reading Newton-Raphson Method

Shock-waves are a common topic covered in undergraduate thermodynamics, fluid mechanics, and gas dynamics courses. Because shock-waves are awesome, I figured I would do one of my first posts on … Continue Reading Stationary Normal Shock Waves
