摘要
In this work, hydrothermal behavior and entropy generation of a heated cylinder placed between two oppositely rotating cylinders inside a vented cavity is studied numerically using the finite volume technique. The mixed convection of a steady, 2D, and laminar flow is considered for the flow through the vented cavity. For counter-rotating cylinders, according to the center of the heated cylinder, two different vertical distances, Zy and three different horizontal distances, Zx are investigated with angular rotational speeds, Omega ranging from 0 to 15. The influence of relevant parameters on hydrothermal behavior, such as Reynolds number (100 <= Re <= 500) and Grashof number (10(3) <= Gr <= 10(6) ) is taken into account throughout the simulations. The numerical results are exposed in terms of various qualitative and quantitative figures. Regardless of the position of counter-rotating cylinders, results show that the optimal thermal performance criterion, xi is achieved at low Reynolds number (Re = 100) over the ranges of angular rotational speeds, Omega.
