Abstract
Jet impingement has been widely used as a means of heat removal because of its advantages in effective removal of locally concentrated heat and easy adjustment to the location where cooling is needed. Typical applications are paper drying, cooling of electronic chips, annealing of glass and elimination of excessive thermal load near the leading edge of gas turbine blade inner surface. More studies of jet impingement cooling are reported on flat surfaces than on concave and convex surfaces. For the flows on concave surface, the centripetal force due to the curvature makes the flow unstable and produces Taylor-Gortler vortices. Such vortices are known to enhance momentum and energy transfer and thereby heat transfer rate on the surface. The present study involves a 2-dimensional simulation of homogeneous air jet impinging normally onto a smooth concave surface from a single slot nozzle by means of the Computational Fluid Dynamics software FLUENT.
