STRAIGHTFORWARD DIMENSIONLESS EXPERIMENTAL FORMULAE FOR FLASH POINT OF BINARY MIXTURES OF TWO FLAMMABLE COMPONENTS

Abstract

Dimensionless experimental formulae based on a rational reciprocal function for orrelation of flashpoint data of binary mixtures of two flammable components ave been developed. The formulae are based on data obtained from flash-point experiments. he proposed approach requires only two coefficients, molar fraction of omponents and flashpoint temperatures of the pure flammable components to be nown in advance. Literature data were used for formulae verification and validation btained results indicate that accuracy is comparable and to some extent better han that of conventional flash point prediction models. Dimensional analysis and caling of data have been performed in order to define the correct construction of he equation fitting flash-point data in dimensionless form using the independent ariables suggested by Catoire. Stefan number relevant flash-point of a single compound r a blend has been defined.
