The global demand for freshwater is increasing due to industrialization and population growth, particularly in remote and arid areas like India. solar energy is abundant and has the potential to produce freshwater from saline water or seawater at a low cost. solar distillation is a promising technology for producing freshwater from saline water or seawater. Most studies have focused on plane stills with heat storage materials and fans to enhance performance. However, heat transfer from the top surface to the heat storage material is low due to water's low thermal conductivity and convection current effect. To improve heat transfer, some researchers have placed a fan inside the pool. Experimental and numerical studies have explored various strategies to enhance the thermal performance of pyramid solar stills, but the pulsating heat pipe-based hybrid pyramid solar still has not been adequately addressed. The proposed proposal aims to develop a novel hybrid pyramid solar still with a systemic joining of pulsating heat pipe and Phase Change Material (PCM), adding fins to distribute heat load uniformly. Experiments will be conducted on pyramidal solar stills with various working fluids, different water levels, and PCM below the basin.
