Simulation studies on multi-stage stacked tray solar still, Solar Energy

n this paper, a computer simulation model is presented for studying the steady-state performance of a multi-stage stacked tray solar still. The model is validated by the results of simulated experiments on a three-stage unit having an immersion type electric heater as the heating source. The results obtained from the model using the modified heat and mass transfer relationships proposed in previous study are in good agreement with the experiments. Numerical results are also presented in the paper to appreciate the relative performance of the proposed multi-stage, stacked tray solar still with a diffusion type, multi-stage solar still.
