Water thickness effect on the fin efficiency and heat transfer for partially wet-surface heat exchanger

Heat and mass transfer, in this paper, is considered in one-row heat exchanger, that fins are hotter than air flow and water is added to fins. Related governing equations are derived by analyzing a two-dimension model in a unique cell of a heat exchange. These equations are numerically solved by finite difference method. Heat transfer and efficiency under partially wet surface are calculated by...

ADOMIAN DECOMPOSITION METHOD AND PADÉ APPROXIMATION TO DETERMINE FIN EFFICIENCY OF CONVECTIVE SOLAR AIR COLLECTOR IN STRAIGHT FINS

In this paper, the nonlinear differential equation for the convection of the temperature distribution of a straight fin  with the thermal conductivity depends on the temperature is solved using Adomian Decomposition Method and Padé approximation(PADM) for boundary problems. Actual results are then compared with results obtained previously  using digital solution by Runge–Kuttamethod and a diffe...

Fin-and-Tube Heat Exchanger Solid Core Advanced Simulation

This paper is devoted to the presentation of an advanced model for the heat conduction processes within a finned tube bundle, typically found in air-cooled evaporators and condensers. As a result of the computational effort needed to simulate the desired fin-and-tube local unsteadiness, some actions have been undertaken in order to obtain reasonable simulation time consumption. A specific cutti...
