A new adsorption model for the spreading dynamics of completely wetting fluids on a heated solid substrate that emphasizes interfacial phenomena is developed and evaluated. The based premise both intermolecular forces temperature affect vapor pressure in change-of-phase heat transfer (therefore) velocity. Classical kinetics, concepts like Clapeyron, Kelvin, augmented Young–Laplace equations are used to evaluate effects stress (change apparent dynamic contact angle), temperature, superheat...
The surface energy of the material used in construction capillary covers is an important element to increase boiling heat transfer on coverings. There are a variety methodologies for measuring solids, but few could be with materials tested. sessile drop methodology allows evaluation either solids or interfacial liquids. uses image digitalization system contact angle liquids solid’s surface. angles thus measured calculate superficial and energies. This was tested experimental set up built...
A vast number of industrial processes require the addition and removal heat at different stages same process. To accomplish recovery there are several technological options with specific characteristics. Thermal integration has been focus recent developments to reduce variable costs through new investments when using fossil fuels for thermal energy generation. The conventional equipment uses conduction convection transfer mechanisms high surface area a metal wall (normally subjected...
Nucleate pool boiling heat transfer increases with certain liquid mixtures and some coatings over the heater’s surface. The effects of these modifications are best measured by relative values convective coefficient that quantify ability for transferring heat. mechanisms increase reflected in formation smaller bubbles escape away from surface at a higher velocity, than those formed under not enhanced conditions. bubble diameter depends on chemical effect composition acting bubble’s interface,...
Factors as the boiling fluid surface tension and characteristics of solid where heat transfer takes place could be modulated for increasing flux. In this work was observed increase in convective heat-transfer coefficient (h) from participation of: (a) use a binary mixture at its critical micelle concentration (16% w/w ethanol-water); (b) addition surfactant sodium-lauryl-sulfate (SLS) to aqueous mixture; (c) porous covering fabricated stainless steel bands with void volume 0.25, pore...
The wettability of the system in capillary covers is an important element to increase boiling heat transfer on coverings. sessile drop methodology allows evaluation either surface energy solids or interfacial liquids, and from both system’s wettability. This was tested with experimental set up built for this study. energies calculated metal foils used construction coverings were accordance previous results. same measuring liquids increasing like ethanol-water mixtures. mixture 16% ethanol by...
The search for suitable mixtures as boiling fluids leads to the development of ternary liquid that could handle even higher heat fluxes than binary through formation stable bubble-micelles departing from heater’s surface. amount experimental work testing combinations is reduced using interfacial tension prediction capabilities simulation software, although it not possible predict singularities in behavior mixtures. ethanol aqueous mixture shows a singularity its value at 16% by weight. In...
