The influence of pressure on the occurrence of micro-explosion has been experimentally investigated for freely-falling miscible multicomponent and water/oil emulsion droplets in hot, oxidizing, high pressure environments up to five atmospheres. Results conclusively demonstrate that increasing pressure not only enhances the possibility of micro-explosion of an otherwise non-explosive mixture, but it also advances the instant of its occurrence during the droplet lifetime. For the range of pressures tested, it is further shown that droplets of alkane and alcohol mixtures do (do not) micro-explode when the volatile component is alcohol (alkane), that droplets of alkane/water emulsions do not micro-explode for alkanes lighter than dodecane, and that while micro-explosion is generally enhanced with increasing water emulsification up to 30% in the low pressure range, the influence may be reversed in the high pressure range. Quantitative results are also presented for ethanol/diesel mixtures and water/diesel emulsions.
