COMBUSTION OF DROPS AND SPRAYS OF NO. 2 DIESEL OIL AND ITS EMULSIONS WITH WATER AND METHANOL. VOLUME II (THEORETICAL)

This report deals with an investigation directed to understand the combustion behavior of No. 2 diesel oil and its emulsions with water and methanol. This Volume (II) of the report presents the theoretical analysis, whereas Volume I describes the experimental studies. Two theoretical models to analyze the variation of drop temperature with emulsion parameters have been developed. The differential model considers the diffusion and specific heat effects inside the composite emulsion drop. The integral model does not consider the temperature variation inside the drop. Analytic solutions for both models have been developed assuming constant properties. The integral model has also been solved numerically considering the variation of properties and using some empirical input data. Both models predict the variation of drop disruption time with the internal phase content in qualitative agreement with the experimentally measured values for the drops of No. 2 diesel oil-water emulsion with water volume fractions up to 0.20.
