Flashpoint prediction for ternary mixtures of alcohols with water for CFD simulation of unsteady flame propagation during explosion

Aqueous solutions of binary and ternary mixtures of alcohols are of considerable interest for a wide range of scientists and technologists. Simple dimensionless experimental formulae based on rational reciprocal and polynomial functions are proposed for correlation of the flashpoint data of binary mixtures of two components. The formulae are based on data obtained from flashpoint experiments and predictions. The main results are the derived experimental flashpoint values for ternary mixtures of two aqueous-organic solutions and the model prediction of maximum explosion pressure values for the studied mixtures. Potential application for the results concerns the assessment of fire and explosion hazards, and the development of inherently safer designs for chemical processes containing binary and ternary partially miscible mixtures of an aqueous-organic system. The goal of this article is to present the results of modelling using these standard models and to demonstrate its importance in the area of CFD simulation.
