Abstract

The present research study includes thermal energy performance analysis of a flat platesolar collector, in order to cover a sensitivity analysis about effective variablescontributed to performance increasing approach. To obtain that, energy and momentumgoverning equations on a flat plate thermal collector were developed to achieve air outputtemperature and velocity profiles both in model and experiment. The model theory isvalidated with experiments by a set of flat plate thermal collectors, those located in(354435′′ N, 505725′′ E) coordinates and then were applied to carry outexperimental activities. Quantitative results depicted that the mean difference betweenpredicted and measured output air temperature in natural and forced convection scenarii is1.47 C (3.5%) and0.9 C (1.5%),respectively; however earlier research works and studies mentioned in literature, includeerror percentages in the range of 4–10%. Another quantification about, the average errorpercentages of estimated amounts of output air velocity profile values in natural andforced convection scenarii is 9% and 4%, respectively. This issue realizes the developedmodel in forced convection scenario more accurate than natural convection scenario.
