RISConjugate Heat Transfer Within a Heterogeneous Hierarchical Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Optimization of heat exchangers (HE), compact heat exchangers (CHE) and microheat exchangers, by design of their basic structures is the focus of this work. Consistant models are developed to ...
Analysis of Flow Induced Vibration Using the Vorticity Transport Equation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Crossflow induced vibrations are the subject of this work. The analysis is two dimensional. The governing equations for fluid motion are solved using linearized perturbation theory and coupled ...
Utilization of Advanced Working Fluids With Biporous Evaporators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel fluid for use as a working fluid in a heat pipe has been tested at UCLA. The fluid was discovered originally in use with a device consisting of a metal tube charged with the ...
Thermophysical Properties of Biporous Heat Pipe Evaporators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thirty biporous slugs with 3 different cluster diameters and 5 different particle diameters (15 combinations with 2 repetitions) and 12 monoporous slugs with 6 different particle diameters were ...
Internal Heat Transfer Coefficient Determination in a Packed Bed From the Transient Response Due to Solid Phase Induction Heating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonintrusive measurements of the internal heat transfer coefficient in the core of a randomly packed bed of uniform spherical particles are made. Under steady, fully-developed flow the spherical ...
Application of Fractional Scaling Analysis to Loss of Coolant Accidents: Component Level Scaling for Peak Clad Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
