Because of the low value convective heat transfer coefficient between absorber plate and air, thermal efficiency a solar air heater is greatly reduced, resulting in high temperatures large losses to surrounding environment. The analysis transmission presented this research, which makes use Computational Fluid Dynamics. An investigation conducted into effect Reynolds number on Nusselt friction f...

Solar drying technology has been widely used in engineering fields such us chemical because of its low cost and pollution advantages. In this review, the structural forms, materials coatings heat-absorbing panels flat plate solar air collector are classified, experimental theoretical results performance level panel summarized. indoor tests, energy efficiency is 30% to 79%, applications 28% 62%.

Abstract For the last 20 years, solar collectors have been developing rapidly in use of energy buildings. Under experimental conditions, utilization efficiency (SEUE) flat plate (FPSC) can reach more than 80%, but engineering application SEUE is low, and even collector heating cannot meet design requirements. In this paper, based on existing thermal performance FPSC, influence ambient meteorolo...
