A three-parameter cubic equation of state has been proposed for predicting PVT of pure refrigerantssuch as R236ea, R236fa, R245fa, R245ca, R218, R227ea, and R717, from freezing point up to critical pointtemperature and pressures up 650 atm. We explore the theory of the equation of state from the view pointof Ihm–Song–Mason (ISM) equation of state, which has been derived on the basis of statisti...

a second virial coefficient correlation suitable for two different temperatures ranges, (t*)-2£180 and (t*)-2>180, where t* is rt/dhvap is presented. the equation of state can be calculated for different, complicated non-polar, and slightly polar liquid mixtures at any temperature over the range from ttp to tc and up to high pressures. the latent heat of vaporization and density at the triple p...

A computational heat and mass transfer model of ceramic precursor solution containing droplets injected into a combustion flame is presented. Upon heat-up and vaporization, the precursor in droplets precipitate and ultimately form the ceramic material. Temperature and solute concentration distributions were computed to estimate the precipitation zones within droplets based on a simple homogeneo...
