Abstract: In this paper, the effect of using a phase-change material (PCM) on the storage capacity of a conventional solar storage system was carried out. This was obtained by using encapsulated spheres that contain paraffin wax as ...

Abstract: In the present work, the Jeffery–Hamel flow problem has been studied using both first- and second-order velocity-slip models, and then compared with the no-slip model. The objectives are to ...

Abstract: In this work, the effect of the second-order term to the velocity-slip/temperature-jump boundary conditions on the solution of four cases in which the driving force is fluctuating harmonically ...

Abstract: Three artificial neural network models [feedforward, Elman, and nonlinear autoregressive exogenous (NARX)] were used to find the performance of two flat-plate collectors operating under Jordanian climate. One collector ...

Abstract: A theoretical analysis was performed to study the attenuation of a heat wave through two composite walls. Each wall was made of three homogenous layers in addition to an insulation layer, all of which were made of local ...

Abstract: An artificial neural network (ANN) model was developed to study the heat transfer analysis in an unglazed flat-plate solar collector with air passing behind the absorbing plate. The construction of the solar air collector ...
