Researchers' task is to save energy in forms that can be turned into the forms that are required. Energy storage minimizes the gap between supply and demand for energy while also increasing the effectiveness and dependability of energy systems. Latent heat storage (LHS) is one of the efficient ways to store energy. This article has explored the numerical analysis of the solidification process for latent heat thermal energy storage (LHTES) in a triplex chamber. TiO2-Al2O3 nanoparticles have been employed as hybrid nanoparticles and water has been used as a phase change material (PCM). Flex PDE uses finite elements to discretize and solve the partial differential governing equations. The effects of several factors on the solid fraction contour, temperature contour, average temperature distribution, total system energy, and solid fraction diagram have then been studied. These parameters include fins, thermal radiation, the volume fraction of nanoparticles, and the shape factor of nanoparticles. Additionally, the optimal values for the full solidification time (FST) have been established using the response surface method (RSM). The findings indicate that full solidification time in hybrid nanoparticle volume fraction 0.048, thermal radiation 0.777, and the shape factor 15.29 are optimized.
