Velocity and Heat Transfer Analysis in Channels with a Porous Wall.
Abstract
A method of cooling turbine blades internally by continuous injection through an interior baffle is analyzed. The analytical model consists of a two-dimensional channel formed by a solid wall (blade surface) and a porous plate (injection source). Based on incompressible and laminar flow assumptions the velocity and the temperature fields are determined. The Nusselt number for a power-law surface temperature variation is obtained and expressed in terms of the Prandtl and Reynolds numbers. The related problem of cooling the turbine disc is also solved. (Author)
