Adequate knowledge of biodiesel's physical properties is necessary to simulate its dispersion, atomization and combustion when it is being used in engines. The objective of this work was to evaluate predictive models of physical properties of seven main methyl and ethyl esters that compose biodiesel to model its combustion. The properties evaluated in this study were: normal boiling temperature, critical temperature, critical pressure, critical volume, acentric factor, saturation pressure, liquid density, enthalpy of vaporization and combustion, liquid viscosity, and surface tension. Satisfactory adjustments were obtained for each property evaluated by comparing estimated values to experimental data available in the literature.

“…Referencing the simple organic composition system, there are several methods for measuring vapor pressure described in the literature. Differential thermal analysis (DTA) instrumentation with the thermocouple-inserted glass capillary configuration is ideally suited for measurement of boiling points at a variety of pressures [15][16][17]. Based on the similar testing mechanism, a recently developed thermo-gravimetric analysis (TGA) method is partly applied to provide a rapid means of quantifying vapor pressure of selected organic compounds [18].…”

Transformer oil as an important mineral oil is widely used in power equipments and its fundamental properties can be obviously presented by the vapor pressure which is difficult to be accurately evaluated due to its complex compounds. According to the testing mechanism of thermal balance, a simple method is proposed to evaluate the vapor pressure of transformer oil at various temperatures. The thermal stability and chemical components of the tested oil are characterized and discussed. The experiment data correlation to the vapor pressure of transformer oil is further performed by the typical Clausius-Clapeyron equation. It reveals that the vapor pressure of transformer oil is positively related to temperature environment. Moreover, a deep comparison between the experiment data and the correlated result confirms that the applied evaluating method is a suitable way to evaluate the vapor pressure of transformer oil and other liquid compounds system.
