RISEffects of Inclination Angle of Ribs on the Flow Behavior in Rectangular Ducts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow behavior in rib-roughened ducts is influenced by the inclination of ribs and the effect is investigated in the present study by Particle Image Velocimetry (PIV). The local flow ...
On Prediction of Thermal-Hydraulic Characteristics of Square-Sectioned Ribbed Cooling Ducts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the results of an investigation on prediction of local and mean thermal-hydraulic characteristics in rib-roughened ducts of square cross section. the Navier–Stokes and energy ...
Analysis of Chemically Reacting Transport Phenomena in an Anode Duct of Intermediate Temperature SOFCs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The internal reforming and electrochemical reactions appear in the porous anode layer, and may lead to inhomogeneous temperature and gas species distributions according to the reaction kinetics. ...
Review on the Properties of Nano-/Microstructures in the Catalyst Layer of PEMFC
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The catalyst layer (CL) of a proton exchange membrane fuel cell involves various particles and pores that span a wide range of length scales, from several nanometers to a few microns. The ...
Heat Transfer Enhancement in Square Ducts With V-Shaped Ribs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper concerns a numerical investigation of the heat and fluid flow in V-shaped ribbed ducts. The Navier-Stokes equations and the energy equation are solved in conjunction with a low ...
Predictions of Enhanced Heat Transfer of an Internal Blade Tip-Wall With Hemispherical Dimples or Protrusions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool ...
Performance Analysis of a Countercurrent Flow Heat Exchanger Placed on the Truck Compartment Roof
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the increasing power requirement and the limited available space in vehicles, placing the heat exchanger at the roof or the underbody of vehicles might increase the possibility to handle ...
PIV Measurement of Separated Flow in a Square Channel With Streamwise Periodic Ribs on One Wall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, particle image velocimetry (PIV) is used to investigate the physical process of separated flow in a square channel roughened with periodically transverse ribs on one wall. The ...
Comparisons of Pins/Dimples/Protrusions Cooling Concepts for a Turbine Blade Tip-Wall at High Reynolds Numbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool ...
CFD Modeling: Different Kinetic Approaches for Internal Reforming Reactions in an Anode-Supported SOFC
Publisher: The American Society of Mechanical Engineers (ASME)
