A study on heat and mass transfer analysis of solar distillation system

The solar stills were developed to fulfil the freshwater need of growing population. paper presents recent modifications made in still improve their productivity like application phase change materials (PCM), connecting flat-plate collector (FPC), use nanoparticles, stepped still, and attaching separate condenser still. Active are found more productive than passive ones thermal efficiency active lie range 50–70%, which is far better having 20–55% efficiency. According literature studied paper, maximum 10 litres per day stills, it 6 day. different approaches used carry out heat mass transfer analysis single double slope also discussed paper.
