Analytical models of thermal performance of solar air heaters of double-parallel flow and double-pass counter flow
TL;DR: In this paper, the authors developed two analytical models that describe the thermal behavior of solar air heaters of double-parallel flow and double-pass counter flow, based on the local energy balances, algebraic expressions for the efficiency factor and overall heat loss coefficient, U L, as well as air temperature distributions along the collectors were obtained.
