Computer modeling of passive/active solar stills by using inner glass temperature
(2003)
Expressions for water and glass temperatures, hourly yield and instantaneous efficiency for both passive and active solar distillation systems have been derived. The analysis is based on the basic energy balance for both ...
Modeling and experimental validation of a greenhouse with evaporative cooling by moving water film over external shade cloth
(2003)
A mathematical model through flowing water film on shade cloth, stretched over the roofs and south wall of an even span greenhouse has been developed to study the effectiveness of cooling in greenhouse. The model was ...
