Experiments were conducted on laminar spray diffusion flames of ethanol/argon burning in oxygen at pressures of 1 and 3 atm. The flames were physically characterized by measuring droplet velocities and sizes by phase-Doppler anemometry, and gas temperature by thin-filament pyrometry and thermocouples. The flames exhibited a cold core, where little vaporization occurred, surrounded by a primary ...

An analytical equation of state by Song and Mason is developed to calculate the PVT properties ofmercury. The equation of state is based on the statistical-mechanical perturbation theory of hard convexbodies and can be written as a fifth-order polynomial in the density. There exists three temperaturedependentparameters in the equation of state; the second virial coefficient, an effective molecu...

Efficient processing, handling, and storage of corn stover, a major crop‐based biomass, require an understanding of the moisture sorption thermodynamic properties of its fractions. Moisture sorption thermodynamic properties of the major corn stover fractions such as leaf, stalk skin, and stalk pith were determined, utilizing the static gravimetric sorption isotherms data in the temperature rang...

This work investigates heat transfer and phase change phenomena during excimer laser interaction with nickel specimens[ Based on time!resolved measurements in the laser ~uence range between 1[4 J cm and 09[4 J cm\ it is found that surface evaporation occurs when the laser ~uence is below 4[1 J cm[ At a laser ~uence of 4[1 J cm or higher\ explosive!type vaporization takes place[ Numerical calcul...

The effect of flow instabilities on flow boiling heat transfer in microchannels is investigated using water as the working fluid. The experimental test section has six parallel rectangular microchannels with each having a cross sectional area of 1054 × 197 microns. Flow restrictors are introduced at the inlet of each microchannel to stabilize the flow boiling process and avoid the backflow phen...

With the rapid depleting of fossil fuels and its pollution intensive research is going on for the alternative fuels which produce low emissions and are should be renewable. Due to the production of sugar cane in our country is more (alcohol is a byproduct in the production of sugar), alcohol is considered as a preferable replacement for the diesel. However due to alcohol high latent heat of vap...
