Mangler’s Transformation in Magnetogasdynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Singular Parabolic Partial-Differential Equations That Arise in Impulsive Motion Problems
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Two-Dimensional Model of the Air Flow and Temperature Distribution in a Cavity-Type Heat Receiver of a Solar Stirling Engine
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Analysis of the Working Process and Mechanical Losses in a Stirling Engine for a Solar Power Unit
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Review of the Computational Fluid Dynamics Modeling of Fuel Cells
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Transparent PEM Fuel Cells for Direct Visualization Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Fluid Flows Through Some Geological Discontinuities
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Through-Plane Permeability for Untreated and PTFE-Treated Gas Diffusion Layers in Proton Exchange Membrane Fuel Cells
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
A Novel Approach to the Optimization of Reaction Rate Parameters for Methane Combustion Using Multi-Objective Genetic Algorithms
Publisher: The American Society of Mechanical Engineers (ASME)
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. ...
Influence of Lift Force on the Settling Velocities of Rotating Particles in Two-Dimensional Shear Flow
Publisher: American Society of Civil Engineers
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 ...
