Scale modeling affords engineers the ability to appreciate the dynamic enclosure fire environment of larger than life structures in the laboratory. Conventional approaches to scaling have expressed results in terms of time-averaged values… Author: Perricone, Jonathan Andrew Source: University of Maryland Download This Report (PDF) Download URL 2: Visit Now Download URL 3: Visit Now
Heat Transfer Coefficient and Pressure Drop Gas Cooling Measurements for CO2/Oil Mixture in a Micro Channel Tube
An experimental study was conducted to measure the heat transfer characteristics and pressure drop of supercritical Carbon Dioxide (CO2) in gas cooling conditions while flowing through a horizontal micro channel. Five experiments were conducted at operating conditions that included an inlet temperature of 70°, inlet pressures of 8 to 10 MPa, a mass flux of [...]
Convection and Flow Boiling in Microgaps and Porous Foam Coolers
An open and foam-filled microgap cooler, providing direct liquid cooling for a simulated electronic/photonic component and which eliminates the problematic thermal resistance of the commonly-used thermal interface material (TIM), is examined. The single phase heat transfer and pressure drop results of water are used to validate a detailed numerical model and, together with the convective [...]
