Flow around a pair of side by side square cylinder in tandem arrangement using Lattice Boltzmann Method

摘要

This thesis introduces a method which is Lattice Boltzmann Method. Flow around square cylinder has been carried out in this project using LBM. The project consisting two-dimensional numerical simulation of isothermal fluid flow around a couple of different size of cylinder aligned along to the main flow direction, at several distances. Vorticity and recirculation zone is studied in detail to find what are parameters affectedudit. The vorticity and the recirculation zone are obtained and compared with other existing results. The simulation is carried out by using FORTRAN and AVS software. This project has been done for low Reynolds Number ranging 10 to 60. The result obtained is well agreed with other researcher by using of simulation software.
