Experimental performance, exergy, and economic analysis of an oval tubular solar still integrated with nano-enhanced phase change material
/day and thermal efficiency to 68.24%. Daily thermal exergy efficiency improved from 3.41% (without PW) to 4.52% (with NAPW), and the production cost decreased from $0.0208 to $0.0163 per liter. The study demonstrates the effectiveness of integrating PCM and nanoparticles in OTSS to improve freshwater yield, thermal performance, and economic feasibility.
