Electronic Thesis and Dissertation Repository
An experimental study on the thermal flow behavior inside a flat-plate collector and the impact of insert devices (passive heat transfer enhancement techniques) on the thermal performance of the collector is presented. Temperature fields were obtained for different Reynolds numbers (250-650) and at different inclination angles of the collector. The results show that a stratified flow is developed inside the collector and the warmer fluid restricts itself to the upper portion of the collector only. Various new configurations of the conventional insert devices were tested over a wide range of Reynolds number (200-8000). Comparison of these devices show that in …
