Abstract
In the present work, natural convection heat transfer from discrete heat sources mounted in rectangular enclosure using liquid coolant is investigated. Heat transfer from discrete heaters is non-uniform and should be accounted for by applying the averaging techniques. The averaged two-dimensional governing equations along with the standard k-e model and wall function are solved using the SIMPLE algorithm. The effects of the e cooling fluid type water and dielectrics oil, the different heat flux and time on heat transfer are investigated. The results are compared with experimental measurements. Results show that water gives a good cooling effect compared with dielectrics oil. Maximum heat transfer occurs at the heater leading and side edges. The heater surface temperature is highest at the top-row heaters. Results show also good agreement between the theoretical and experimental measurements.
