COMPUTER SIMULATION OF PHYSICAL PROCESSES INCLUDING MODELING OF LAMINAR-TO-TURBULENT TRANSITION

摘要

A computer-implemented method for simulating fluid flow using a lattice Boltzmann (LB) approach that includes assigning values for the wall shear stress on a per-facet (e.g., per-surfel) basis based on whether the fluid flow is laminar or turbulent is described herein. This description relates to computer simulation of physical processes, such as fluid flow and acoustics. This description also relates to a method for predicting the phenomena of laminar-to-turbulent transition in boundary layers.
