Numerical Simulation of Flow Around Two Rotating Circular Cylinders in Staggered
Arrangement by Multi-Relaxation-Time Lattice Boltzmann Method at Low Reynolds Number
Abstract: The flow field around two rotating circular cylinders arranged in a staggered configuration is studied numerically using Lattice Boltzmann method via multi-relaxation-time approach. The flow simulations are carried out at various values of absolute rotational speed 0< K< 2, gap spacing of 0.5 and angle of incidence ranging from =0° to 90° at Reynolds number of 100.Results are presented in the form of streamlines, vorticity and pressure contours. Moreover, effects of the above parameters on drag and lift coefficients are investigated. The results show that the arrangement and rotational speed of cylinder have significant effect on drag and lift coefficients.
