This post is a simple demonstration of the timeVaryingFixedUniformValue boundary condition. This boundary condition allows a Dirichlet-type boundary condition to be varied in time. To demonstrate, we will modify the oscillating cylinder case. Set-Up Instead of using the oscillating boundary condition for point displacement. We will have the cylinder do two things: Move in a … Continue reading Time-Varying Cylinder Motion in Cross-flow: timeVaryingFixedUniformValue

Validation: Turbulent Zero Pressure Gradient Flat Plate – simpleFOAM, komegaSST
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 this problem using the solver simpleFoam and the komegaSST model. Here are the sections of this post: Quick Overview: kω-SST (komegaSST) Boundary Conditions Case set-up … Continue reading Validation: Turbulent Zero Pressure Gradient Flat Plate – simpleFOAM, komegaSST
Pressure Driven Nozzle Flow with Shock – rhoCentralFoam
In this post I will go over the set up and solution of a pressure driven nozzle flow with a shock located in the diverging section. This refers to the type of flow problem described by region b in my page covering stationary normal shock-waves. Here is a summary of the contents of this post: Nozzle Design … Continue reading Pressure Driven Nozzle Flow with Shock – rhoCentralFoam
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. A finite height is required because at Mach 1.5 the leading edge shock-wave is detached for a deflection angle of 23 degrees. Without a finite height the shock wave standoff distance would be indeterminate. Here is … Continue reading Mach 1.5 flow over 23 degree wedge – rhoCentralFoam
