RISExperimental Investigation of Heat Transfer in Impingement Air Cooled Plate Fin Heat Sinks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Impingement cooling of plate fin heat sinks is examined. Experimental measurements of thermal performance were performed with four heat sinks of various impingement inlet widths, fin spacings, ...
Pressure Drop of Impingement Air Cooled Plate Fin Heat Sinks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance of impingement air cooled plate fin heat sinks differs significantly from that of parallel flow plate fin heat sinks. A simple impingement flow pressure drop model based on ...
Optimal Distribution of Heat Sources in Convergent Channels Cooled by Laminar Forced Convection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The constructal theory is applied to the flow in a convergent channel. The primary goals of this work are to analyze the heat source distribution and generalize the formula concerning such ...
Effects of Corrugated Roughness on Developed Laminar Flow in Microtubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of corrugated surface roughness on developed laminar flow in microtubes are investigated. The momentum equation is solved using a perturbation method with slip at the boundary. Novel ...
Laminar Non-Newtonian Fluid Flow in Noncircular Ducts and Microchannels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Non-Newtonian fluid flow in noncircular ducts and microchannels is examined. A simple model is proposed for power law fluids based on the Rabinowitsch–Mooney formulation. By means of a new ...
Slip Flow in the Hydrodynamic Entrance Region of Circular and Noncircular Microchannels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microscale fluid dynamics has received intensive interest due to the emergence of micro-electro-mechanical systems (MEMS) technology. When the mean free path of the gas is comparable to the ...
Effects of Axial Corrugated Roughness on Low Reynolds Number Slip Flow and Continuum Flow in Microtubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of axial corrugated surface roughness on fully developed laminar flow in microtubes is investigated. The radius of a microtube varies with the axial distance due to corrugated ...
Slip Flow Heat Transfer in Annular Microchannels With Constant Heat Flux
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microscale fluid dynamics has received intensive interest due to the emergence of microelectromechanical systems technology. When the mean free path of the gas is comparable to the channel’s ...
Pressure Drop in Laminar Developing Flow in Noncircular Ducts: A Scaling and Modeling Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A detailed review and analysis of the hydrodynamic characteristics of laminar developing and fully developed flows in noncircular ducts is presented. New models are proposed, which simplify the ...
Asymptotic Generalizations of the Lockhart–Martinelli Method for Two Phase Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The (1949, “Proposed Correlation of Data for Isothermal Two Phase Flow, Two Component Flow in Pipes,” Chem. Eng. Prog., 45, pp. 39–48) method for predicting two phase flow pressure drop is ...
