Parallel Flow Through Ordered Fibers: An Analytical Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, fully developed flow parallel to ordered fibers is investigated analytically. The considered fibrous media are made up of in-line (square), staggered, and hexagonal arrays of ...
Slip-Flow Pressure Drop in Microchannels of General Cross Section
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present study, a compact analytical model is developed to determine the pressure drop of fully-developed, incompressible, and constant properties slip-flow through arbitrary cross section ...
Thermal Assessment of Naturally Cooled Electronic Enclosures With Rectangular Fins
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Passive heat transfer from enclosures with rectangular fins is studied both experimentally and theoretically. Several sample enclosures with various lengths are prepared and tested. To calibrate ...
Thermal Joint Resistance of Polymer-Metal Rough Interfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A compact analytical model is proposed for predicting thermal joint resistance of rough polymer-metal interfaces in a vacuum. The model assumes plastic deformation at microcontacts and joint ...
Pressure Drop of Fully-Developed, Laminar Flow in Microchannels of Arbitrary Cross-Section
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The pressure drop of fully developed, laminar, incompressible flow in smooth mini- and microchannels of arbitrary cross-section is investigated. A compact approximate model is proposed that predicts ...
Pressure Drop of Fully Developed, Laminar Flow in Rough Microtubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Advances in fabrication methods in microelectromechanical systems (MEMS) have generated significant interest in the area of microscale heat transfer and fluid flow. Microchannel heat exchangers can ...
A Compact Model for Spherical Rough Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new model is developed that considers the effect of roughness on the elastic contact of spherical bodies. A general pressure distribution is proposed that encompasses the contact of rough ...
Convective Heat Transfer in Microchannels of Noncircular Cross Sections: An Analytical Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Analytical solutions are presented for velocity and temperature distributions of laminar fully developed flow of Newtonian, constant property fluids in micro/minichannels of hyperelliptical and ...
Review of Thermal Joint Resistance Models for Nonconforming Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The thermal contact resistance (TCR) in a vacuum is studied. The TCR problem is divided into three different parts: geometrical, mechanical, and thermal. Each problem includes a macro- and ...
