Experimental and Numerical Investigation of a Device for Localized Cooling

The present paper is based on the experimental and numerical investigation of a cooling device. The device is focused to concentrate cooling effect on a specific zone in a given three-dimensional volume. A wall jet configuration is investigated on a curved surface initially with a straight portion. The mean flow parameters are measured like, mean velocity profiles, maximum velocity decay and jet growth rate and temperature. The same result shave has been calculated using commercial CFD code. The mean velocity profiles show good agreement with the experimental and with the existing literature. Maximum velocity decay, growth of half width and temperature profiles show good correlation with the experimental results. The existing system parameter of the device is found to be appropriate to achieve the solution of the localized cooling concept.
