| dc.description.abstract | Fresh water is a very important need for humans. One of the tools that can
be a solution to overcome the increasing need for fresh water is a solar still. One
of the main components in the solar still that contributes greatly to the
effectiveness of the solar still is the absorber plate. However, currently no one has
conducted an in-depth analysis of the effect of absorber plate temperature
variations on the productivity and heat transfer of solar stills numerically using
CFD simulations. Therefore, this study analyzes the effect of absorber plate
temperature variation on solar still performance using CFD simulation. The
model used is a solar still with a 30-degree slope with absorber plate temperature
variations of 50°C, 60°C and 70°C. Gravity, transient method, multiphase, heat
transfer and mass transfer are considered in the simulation. The simulation
results found that the absorber plate temperature greatly affects the productivity
and heat transfer that occurs in the solar still. At an absorber plate temperature
of 50 °C, it will produce a condensation water productivity rate of 1.05
grams/minute and a total heat transfer of 43.90 watt. so that increasing the
absorber plate temperature to 60 °C, and 70 °C will increase the condensation
water productivity by 96%, and 142%, respectively. And by increasing the
absorber plate temperature to 60°C, and 70°C will increase the total heat transfer
rate by 37.81% and 71.91% respectively. | en_US |
