Thermal characteristics of TIMs with elliptical particles

In this study, direct numerical simulations of suspended particles are used to characterize the heat transfer properties of TIMs. The computational method is based on the solution of a thermal lattice-Boltzmann method. Based on the simulations, the effect of particle parameters such as loading, thermal conductivity and size on the thermal resistance of the TIM can be predicted. The effect of particle shape is also considered. Elliptical particles with different aspect ratios are examined. Cylindrical particle is a special case with aspect ratio of 1. The results are compared with existing data. The results can be used to design TIM for better thermal performance.
