Improving Heat Transfer through Paraffin Wax for Sustainability Heat Pump
Journal Title: International Journal of Innovation in Science and Mathematics - Year 2018, Vol 6, Issue 5
Abstract
The objective of the present work is to study the effect of the solar collector inclination angle, paraffin specifications and paraffine cavity high on the performance of the thermal pump numerically at different time. Also the performance of sensible thermal energy storage (STES) system is investigated to use as the cold storage into the solar heat pump. The Navier - Stokes equations (momentum equations) of the flow are solved for turbulent, 2-D, steady state, incompressible, and no slip conditions; while the energy equation of the heat transfer fluid is solved for unsteady state condition. The heat conduction in the phase change material (PCM) is considered as unsteady 2-D heat conduction problem using the effective heat capacity method for PCM. The governing equations are discretized using finite-volume method - upwind differencing scheme. These equations are solved using SIMPLE algorithm method on staggered grid with Fluent code 16.0 to obtain the velocities distribution, and then the energy equations for the fluid and the periphery domain (PCM) are solved simultaneously in the separately program as second step. The calculations of the velocity, temperatures distribution, and then the Nusselt number values with different Rayleigh number for air at both heat collectore room and paraffine wax room at different daytime are reported. According to the climate in the city of Basra, the angle of 30 degrees is the most effective in absorbing heat. Also the results show both paraffin specifications and paraffine cavity high have significant effect on the performance of the thermal pump.
