Abstract: The lattice Boltzmann method is employed to simulate heat transfer in the flow past three arrangements of elliptical and circular cylinders under an isothermal boundary condition. The lattice Boltzmann equations and the Bhatnagar-Gross-Krook model are used to simulate two-dimensional forced convection at $3\le\mathrm{Re}\le 100$, $\operatorname{Pr} = 0.71$. Pressure distributions, isotherms, and streamlines are obtained. Vortex shedding maps are observed in detail for several cases. The present results are in good agreement with available experimental and numerical data.

Keywords: lattice Boltzmann model, isothermal cylinders, vortex shedding, Reynolds number.
