• Resumen

  • In this paper, we have studied paraffin heat transfer in melting process in solar water heater storage tanks by numerical investigation. We have used Gambit software for geometrical production. The output of this software has been used as the input for ANSYS Fluent. We have also used SIMPLE algorithm for solving algebraic equations. As for momentum equations we have used second-order upstream discretion and for other alternatives including kinetic energy and turbulence loss and finite volume transfer equation we have used first-order upstream discretion. The results show that the average heat goes up by the increase in the number of fins and reduces the melting time of phase change material (PCM). Also with the increase in the length of the fins more quantity of the material changes phases and turns into liquid. With the increase in thickness of the fins, minimal increase is seen in phase change of the material and its liquidation.
