Convective cooling of tandem heated triangular cylinders placed in a channel

Abstract

Numerical simulations of forced convective incompressible flow in a horizontal plane channel with adiabatic walls over two isothermal tandem triangular cylinders of equal size are presented to investigate the effect of wall proximity of obstacles, gap space (i.e. gap between two squares), and Reynolds number. Computations have been carried out for Reynolds numbers of (based on triangle width) 100, 250, and 350. Results show that, wall proximity has different effect on first and second triangle in fluid characteristics especially in lower gap spaced, while for heat transfer a fairly same behavior was seen.

Computational fluid dynamics modeling patterns and force characteristics of flow over in-line four square cylinders

“…The results show that when the flow is unsteady, the downstream cylinder experiences very large unsteady forces that may lead to wake-induced flutter. Other papers of flow characteristics about flow over two cylinders in different configurations were published in [4][5][6], and in other studies, that relate to heat transfer and fluid flow over two cylinders can be found in the contemporary literature [7][8][9][10].…”
