Abstract

Sheared convective boundary layers (SCBL) are a frequently observed boundary layer in nature and industry. This paper presents work conducted to validate a numerical fluid model of sheared convective boundary layers implemented in Nvidia's CUDA programming language for graphical processing units. The code is based on finite difference implementation of the SIMPLE algorithm using the Boussinesq approximation to couple the energy equation through the buoyancy term. Work presented shows validation of the model on simpler test cases that are more thoroughly understood, and the model shows agreement with physical phenomena.
