“…The combination proved successful in minimizing the maximum temperature among the heat sources at competitive times. More recently, Radhakrishnan et al (2010) investigated the optimal placement of heated objects in a vented enclosure, both numerically and experimentally. They used the response surface method to maximize heat transfer and minimize temperature deviations from the target temperature.…”

Purpose -This paper presents the heat transfer enhancement from discrete heat sources using a wavy channel. Design/methodology/approach -The finite element method is utilized to solve the hydrodynamic/thermal problem. The considered geometry consists of a channel formed by two wavy plates with six discrete heat sources placed on upper and lower walls. The global objective is to maximize the heat transfer from the heat sources. The wavy channel enhances heat transfer from the heat sources through the modification of the flow pattern in the channel. The effects of the Reynolds number, Prandtl number, waviness of the wavy wall, and the location of the heat sources on the thermal characteristics of the flow are investigated. Findings -Results indicate that the wavy channel significantly enhances the heat flow out of the heat sources, with heat sources located at the minimum channel cross sections having the best performance. The Nusselt number increases with an increase in Reynolds number and waviness of the wavy channel. The higher Prandtl number has a positive effect on the heat flow out of the heat sources. The heat transfer enhancement can reaches as high as 120 percent for high Reynolds numbers and waviness of the channel. Originality/value -The combination of wavy plates and optimum placement of heat sources can lead to better, less expensive thermal management of heat sources in electronic devices.
