Влияние частоты расположения ребер радиатора на плавление парафина с добавлением наночастиц

Abstract

Heat transfer inside the copper heat sink filled with nano-enhanced paraffin is studied numerically. The hydrodynamic equations were written in dimensionless stream function and vorticity. The energy equation is combined for the melt and solid paraffin by means of the smoothing function φ which determines smooth changes in the latent energy and thermophysical properties of the material during the transition through the interphase. The system of partial differential equations was solved by using the finite difference method. Influence of number of fins and nanoparticles volume fraction on melting regime and natural convection was investigated.
