Abstract

Detached eddy simulation (DES) method is applied to investigate the influences of curved hole passage on the turbulent flow characteristics of jet in cross flow (JICF) for film cooling vane. Two types of hole configurations, straight and curved holes, on a flat plate are simulated at blowing ratio 0.5, with Reynolds number Re D=4000 based on the hole diameter and main flow speed. The influences of hole curvature on film cooling are studied from the viewpoints of scalar turbulent advection. Both the longitudinal and transversal two-point auto-correlations of the fluctuating velocity and the corresponding wave number spectra are analyzed. More attention is paid at the differences, caused by hole curvature, in the statistical view of the turbulent flow structures and the transportation of turbulent energy from the energy-containing range to the smaller inertial sub-range in the wake region.
