The effect of nonuniform fluid flow distribution on the thermal performance of solar collector

In the design of solar collector, every effort is made to provide an uniform fluid flow distribution among the flow channels of the collector. Economical and space considerations, however, may make the uniform fluid flow distribution through the solar collector unrealistic. If the fluid flow distrib...

Description
Summary:In the design of solar collector, every effort is made to provide an uniform fluid flow distribution among the flow channels of the collector. Economical and space considerations, however, may make the uniform fluid flow distribution through the solar collector unrealistic. If the fluid flow distribution is not uniform, the thermal performance of the solar collector may deteriorate. A numerical method is developed for determination of the deterioration of thermal performance of solar collector due to this flow nonuniformity effect. Using several typical fluid flow maldistribution models, the collector efficiency and its deterioration are determined for various collector design and operating conditions.
