... Two-Phase Vaporization Evaporative spray cooling has been exhibited to be an effective method of removing high heat fluxes from surfaces with low superheat. For water as the working fluid, a spray cooling heat flux of 1000 W/cm 2 was reached 1 . The heat flux enhancement due to spray...

...Michael Epstein This paper presents a one-dimensional steady-state model of heat and water vapor transport just beneath an ablating concrete surface. In the model an evaporation front separates a dry porous region through which water vapor flows to the ablation front from a semi-infinite region...

... by a physical model 17 applied to the Hg-water system. In thismodel the abrupt vaporization is assumed to dominate the explosive pressure generation. The generated pressure by heating of materials increases as the laser fluence F increases. The thickness of the mercury layer has little influence upon...

... transfer Boiling Evaporation Heat Transfer Non-Equilibrium Vaporization The Knudsen number (Kn) is defined as the ratio of the mean free path of a gas, λ, to a dimension of an object which interacts with the gas, x , (1) Kn = λ x . According to Rohsenow and Choi 1...

... stagnation flow equations for the heat transfer and fluid flow phenomena are derived for the region near the centerline of the laser beam. The analysis accounts for conduction in the solid, conduction, and convection in the melt layer, and the latent heats of melting and vaporization. The stagnation flow...

...W. H. Chen The flame structure and stability, as well as the vaporization rates of twin droplets exposed to a high-temperature, partially premixed flow are investigated in the present study. Two important parameters of the Reynolds number and ambient equivalence ratio are taken into consideration...

Some investigators have proposed that the discharge...
