Turbulent flow model
|Abstract:||The objective of this study is to investigate the cooling performance of the liquid jet impingement of a cold plate heat sink with different fin geometries using water and nanofluids as working fluids. In experiments, the monitored parameters mainly focus on the effects of different heat flux, the water mass flow rate, and heat source area on its thermal resistance. In the numerical study, a three-dimensional of a single-phase and two-phase Eulerian turbulent flow models are used to visualize the temperature and fluid flow behaviors of the cold plate heat sinks. The initial and the boundary conditions of the model based on the experimental conditions. It indicated from the experiments that the increasing of Reynolds number, heat source area, and power input results in decreased thermal resistance. Using nanofluids as working fluid gives the thermal resistance lower than de-ionized water as the working fluid. Additionally, the predicted results have verified with the measured data. It found that good agreement is obtained and gives an average error of 2.69%, 11.77% for CP base temperature and thermal resistance, respectively. © 2019 Elsevier Ltd|
