Transient investigation of a thermosyphon flat-plate solar collector

摘要

In this paper, thermosyphon flat-plate solar collectors are investigated theoretically and experimentally under transient conditions. The governing, equations of the different components of the collector are presented and generalized in dimensionless forms. The finite difference technique is used to solve the set of dimensionless governing equations by means of a simulation program. For verifying the simulation program a thermosyphon flat-plate solar collector is designed, constructed, and tested at transient conditions, different mass flow rates of cooling water, and different inlet cooling water temperatures. The experimental results are compared with their corresponding simulated ones. The comparison shows considerable agreement between the experimental and simulated results.
