Nowadays there is a serious need for the development of the alternative, appropriate, cheap rnmethod of energy use of cooking. In Ethiopia, the majority of the population depends on biomassrnfor cooking applications. However, to avoid this drawback, alternative energy is needed. Hence,thernoverall purpose of this paper deals with the design and analysis of thermal energy storage usingrnsolar salt combnation of 60%NaNO3 and 40%KNO so as to avoid enrgy demand and supplyrnproblem. It provides a high energy storage density at a constant temperature which corresponds tornthe phase transition of phase change material (PCM). At the time of energy available from thernsolar source, a PCM energy storage technology is selected and designed which will be used forrnlater cooking application.The basic design of the study was using steel materials as a tank (shell)rnfor thermal energy sorage, copper tube encapsulated with PCM material. Heat transfer fluid(air)rnwas selected for the model. In addition, two-dimensional Governing equations like continuity,rnmomentum, and energy were discretized by using the finite volume method (FVM). Thus, all therntransient 2D numerical simulations during the charging and discharging process were carried outrnusing the commercial software CFDANSYS Fluent 17.2.As a result,a charging efficiency (70.1%)rnand discharging efficiency(36.9 %) was obtaind during simulation of thermal energy storage unitrnby using different mass flow rate. It was observed that the energy stored during charging (30096.47rnKJ) and the discharged energy(83454.83KJ) were possibliy used for cooking.This energies werernfound to be a suitablel design for an indoor cooking application.
