Natural convection in groove-like geometries - The overall heat transfer coefficient
Abstract
Groove-like geometries are being used to form non-tracking concentrating solar energy collectors. Experimental determinations of the overall heat loss coefficients from a trapezoidal groove, heated from the short side and insulated on the sloping sides are reported. The effects of tilt and internal baffling are investigated. The relative importance of the various modes of heat transfer is analyzed.
