Some recent papers

This post is bit of an advertisement, in that I wanted to share with you some recent papers that I was involved in. Recent here is to be taken with a bit of grain of salt, since some the papers noted below are from as far back as 2010.

Current Density Limit

Ion thrusters are space charge limited devices, with maximum current density given by the Child Langmuir law. This simulation code explores the impact of space charge saturation on the flow between two planar electrodes.

Converting Scalars to RGB Colormap

We can visualize variation of mesh-based scalars by converting each scalar to a color with the help of some colormap. This article describes how to convert a scalar to the rainbow colormap, which ranges from blue to red as the value increases from t...

Flow in a Nozzle

By considering one-dimensional flow, we can derive an expression for the variation of Mach number in a nozzle with a variable area change. Such a relationship is explored here with an interactive demo that allows you to change the shape of a convergi...
