Abstract

In this paper, the hydrodynamics and the thermal behavior of the flow in a rotating U-shape channel and also the effective parameters are studied. This kind of flow is most applicable in INTERNAL COOLING of GAS TURBINE BLADES. In this study, because of the complication of geometry, it has been divided into distinct zones and using different relative coordinate systems, the flow has been analyzed. Also, the grid is staggered and the governing equations are formulated explicitly, using finite difference method. In this paper, the hydrodynamics and the thermal behaviors of coolant fluid are simulated by numerical modeling at rotary and stationary blade and the effective parameters, such as turbine ROTATION radius, radius of internal arc curvature, blade STAGGERED ANGLE, and ROTATION number are studied at two- and three-dimensional conditions. The recent considerable result of this research is the study of the manner of secondary flows interaction that formed due to curvature and ROTATION at different STAGGERED ANGLE and effect of this interaction in heat transfer.
