Original Abstract

In this paper, a CFD investigation of the heat transfer on two grooved cylinders is investigated with L/D = 4.2 and Reynolds number of 2 × 104. Two cases are performed, smooth-smooth cylinders (case 1) and grooved-grooved cylinders (case 2). Two longitudinal grooves are placed on the external surface at 90 and 270 deg. Each cylinder has two grooves on the external surface of the cylinder. The steady-state Reynolds-averaged Navier-Stokes equations are solved using a finite volume method, where k-! SST turbulence model is used to produce a closed system of solvable equations. The tandem cylinders’ geometry simulations are performed at steady conditions. An adapted grid using static pressure, pressure coefficient, and velocity gradient, and furthermore, a second-order upwind scheme, were used. The obtained results show that the numerical predictions are in good agreement with the experimental measurements. The local Nusselt number distributions for all cylinders are described. The influence of the grooved cylinder on the heat transfer is well exhibited.
