摘要：
This paper presents an efficient numerical investigation of a PCM-based heat sink for the purpose of thermal management, that leads to determine its optimal configuration. This study is based on experimental results, where a comparison between heat sink with and without phase change material (PCM) was carried out. Furthermore, a detailed analysis of various parameters' effects of the studied PCM-based heat sink in relation with geometry, boundary conditions and material parameters were studied. Numerical results show that nEicosane increases clearly the thermal performance of the studied cooling system, comparing with other studied PCMs. In addition, increasing the volume fraction of PCM leads to delay the latent heating phase and then increase the thermal management behavior. Also, as expected, increasing the input power level leads to increase the melting rate of PCM. The parametric analysis lead finally to define an optimal design with an efficient thermal performance, for both charging and discharging phases.
