Analytical Considerations of the Flow Boiling Heat Transfer in Metal-foam Tubes
A newly simplified microstructure model of metal foams was carried out for flow boiling heat transfer in metal-foam filled tube. Fin analysis, heat transfer network and superposition correlation were adopted to obtain the equivalent heat transfer coefficient for flow boiling. Based on annular pattern, fluid can be divided into vapor region in the center of the tube and liquid region near the wa...
متن کاملMulti-objective Crashworthiness Optimization of the Aluminum Foam-filled Tubes
In order to reduce both the weight of vehicles and the damage of occupants in a crash event simultaneously, it is necessary to perform a multi-objective optimization of the automotive energy absorbing components. In this paper, axial impact crushing behavior of the aluminum foam-filled thin-walled tubes are studied by the finite element method using commercial software ABAQUS. Comparison of the...
متن کاملA Model for Correlating Flow Boiling Heat Transfer in Augmented Tubes and Compact Evaporators
The additive model for the convective and nucleate boiling components originally suggested by Bergles and Rohsenow (1964) for subcooled and low-quality regions was employed in the Kandlikar correlation (1990a) for flow boiling in smooth tubes. It is now extended to augmented tubes and compact evaporators. Two separate factors are introduced in the convective boiling and the nucleate boiling ter...
متن کاملExperimental measurement of heat transfer coefficient and mass of deposited CaSO4 in subcooled flow boiling condition
Fouling is a common, fundamental and costly problem in heat transfer systems, which reduces thermal efficiency of equipment, increases the energy loss and causes strong damage to the heat transfer equipment in various industries. The main causes of fouling on the heat transfer surfaces are salts with inverse temperature-solubility in the fluid which calcium sulfate is one of the most important ...
