Impinging jet cooling on concave surfaces

Abstract

The numerical modeling of jet impingement cooling onto a semicircular concave surface is reported.

Parametric study of turbulent slot-jet impingement heat transfer from concave cylindrical surfaces

“…Among the recent experimental [19] numerically investigated the hydrodynamics of turbulent slot-jet impingement on convex semi-cylindrical surfaces without any heat transfer consideration. Souris and Liakos [20] have done numerical studies on impingement cooling on concave cylindrical surfaces using the standard k-3 model and the Reynolds stress transport model along with the non-equilibrium wall function [21] for both models. They compared their predictions with the experimental data of Choi et al [18] and found a satisfying agreement between the numerical prediction and experimental data using both turbulence models.…”

Computational Investigation of Flow and Heat Transfer for a Row of Circular Jets Impinging on a Concave Surface

“…Very few computational studies [15][16][17][18] are reported on jet impingement on concave surface. Kayansayan and Kucuka [15] studied single two dimensional slot jet with symmetry condition.…”

“…They presented numerical results for low Reynolds number (up to Re of 600). Jia et al [16] and Souris et al [17] also reported results on slot jet impingement with high Reynolds number of 1780 to 20000 by using different turbulence models. They recommended kmodel to take advantage of simplification and low computational requirements.…”

Micro scale jet impingement cooling and its efficacy on turbine vanes : a numerical study

“…Numerical study of slot jet impingement on concave surface was carried out by Souris et al [25] and a higher Nusselt number was noted for H/B = 6.…”
