Combined Effects of Rotation and Skew Angle on the Convective Heat Transfer in a Two-pass Passage with a 180-degree Turn
SINOPSIS
Heat transfer and fluid flow characteristics in a rotating two-pass square passage with a sharp 180-degree turn are investigated numerically. The channel is aligned with a skew angle to a rotating axis. The configuration simulates the internal air cooling of a turbine blade. The present study focuses on the combined effects of rotation and skew angle on the two-pass passage with a sharp 180-degree turn. The computational procedure solves full three-dimensional Navier-Stokes equation using a finite volume method with the SIMPLE algorithm. Computations were performed for the Reynolds number in the range from 100 to 500, for the Prandtl number of 0.717, for the Rossby number in the range from 2.55 to ∞ and for the skew angle in the range from 0 to 45°. The flow patterns, the overall pressure drop, the peripheral averaged Nusselt number and the bulk temperature at the outlet of the passage are presented as a function of the governing parameters.
