摘要
Two dimensional laminar shear flow pass two equal-sized circular cylinders in tandem arrangement are investigated numerically. Lattice Boltzman method via single-relaxation-time (SRT) collision model is applied to simulate the flow field. Simulations are performed for Reynolds number (Re=200) while the nondimensional shear rate (K) and gap spacing range as 0 <= K <= 0.2 and 0.5 <= g*<= 6. Results show that all these parameters have significant effects on flow pattern. Quantitative information about the flow variables such as drag and lift coefficients and vorticity distributions on the cylinders is highlighted.
