Liquid fuels are still the primary power source due to its higher energy density and ease of operation compared to gas fuels. Thus a detailed understanding of the spray vaporization and combustion characteristics for various liquid fuels are very important, down to a single droplet. Owing to difficulties in performing droplet level investigation in an actual spray, the spray models are mostly d...

(Subcooled) liquid vapour pressures and heat of vaporization of low-volatility isomeric organic compounds (tetrachlorobenzyltoluenes, TCBTs) were determined by two gas-liquid chromatographic (GLC) methods, By the first method vapour pressures and temperature-independent heats of vaporization of nine TCBTs were obtained at experimental temperatures (433.15-493.15 K) and linearly extrapolated to ...

In this work an analytical equation of state has been employed to calculate the PVT properties ofternary refrigerant mixtures. The theoretical EoS is that of Ihm, Song and Mason, which is based onstatistical-mechanical perturbation theory, and the two constants are enthalpy of vaporization ΔHvapand molar density ρnb, both at the normal boiling temperature. The following three temperaturedepende...

A Carnot type engine with a changing phase during the heating and the cooling is modeled with its thermal contact with the heat source. In a first optimization, the optimal high temperature of the cycle is determined to maximize the power output. The temperature and the mass flow rate of the heat source are given. This does not take into account the converter internal fluid and its mass flow ra...
