Abstract
Numerical investigations of a two-pass internal cooling channel with engine-similar cross-sections were conducted. The channel features a trapezoidal leading edge duct, a sharp 180 bend and a nearly rectangular trailing edge duct. Calculations were conducted for a smooth and a ribbed channel (alpha = 45°, P/e = 10, e/dh = 0,1) at Re=50,000 and Ro = 0, Ro = 0.02, Ro = 0.05 and Ro = 0.10. The Reynoldsaveraged Navier-Stokes equations were solved by two different finite-volume solvers, the DLR in-house code Trace and the commercial software Fluent. A standard k epsilon turbulence model by Wilcox with additional modifications for rotating flows and stagnation point behaviour was applied in Trace. Calculations with Fluent were performed using a low-Re k
