A suitable width-size of a channel flow for obtaining the velocity profiles by using the Lattice Boltzmann method

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding


The Poiseuille flow has been widely analyzed from analytical and experimental point of view with different approaches. Although the Lattice Boltzmann method (LBM) has proven to be a suitable tool for mimicking the fluid flow behavior not only for complex but also for simple geometries such as lid driven cavity and channel flow, the required computational size or characteristic length to obtain an acceptable approximation of the described physical phenomena has to be defined. The aim of this study is to evaluate the impact of considering different width-sizes of a channel flow when the velocity profiles are obtained. Channel flow with several width-sizes are evaluated while keeping the Re and aspect ratio as constant.
