Abstract

Two-dimensional numerical simulations for heated and unheatedflows arounda single and two circular cylinders in tandem are conducted. The effect of heating on the flow is studiedby modelling the thermophysical properties of the fluid fitted as polynomial functions of temperature. For the single cylinder case, Reynolds numbers of Re=80, 100, 150, and 200 are considered at different temperature ratios(T∗=
