Abstract: The thermal boundary layer over a semi-infinite flat plate is investigated. For time t < 0 there is the Blasius boundary layer and no thermal boundary layer. At t = 0, a temperature ...

Abstract: A theoretical study on the air flow and temperature in the heat receiver, affected by free convection, of a Stirling Engine for a Dish/Stirling Engine Power System is presented. The standard ...

Abstract: In this paper a second level mathematical model for the computational simulation of the working process of a 1-kW Stirling engine has been used and the results obtained are presented. The ...

Abstract: This paper presents a review of the current situation in the computational fluid dynamics (CFD) modeling of fuel cells and highlights the significant challenges that lie ahead in the development ...

Abstract: This paper reviews some of the previous research works on direct visualization of water behavior inside proton exchange membrane (PEM) fuel cells using a transparent single cell. Several papers ...

Abstract: In this paper the fluid flow through some composite channels has been investigated in the physical parameter ranges appropriate to some flows in geological applications. In particular, we have ...

Abstract: The through-plane permeability has been experimentally measured for untreated and polytetrafluoroethylene-treated (PTFE-treated) gas diffusion layers (GDLs), as used in proton exchange membrane fuel ...

Abstract: This study uses a multi-objective genetic algorithm to determine new reaction rate parameters (A’s, β’s and Ea’s in the non-Arrhenius expressions) for the combustion of a methane/air mixture. ...

Abstract: We derive a simple theoretical model for estimating the change in the magnitude of the particle slip velocity and the deflection in the trajectory of a particle induced by the lift force acting on a freely rotating particle ...
