Abstract

This work was undertaken as part of an investigation of a thermal explosion phenomenon, occurring occasionally under specific conditions, when two liquids of different volatility, are mixed. The 'thermal explosion efficiency coefficient' is used for the determination of the fraction of the thermal energy initially available in the hot liquid (less volatile, called 'fuel') which is converted into destructive mechanical energy by the explosive expansion of the colder liquid (volatile, called 'coolant'). This complex phenomenon consists of separate stages, forming a chain of many events, which must occur - if an effective and large scale thermal explosion is to take place. Two separate phases 'A' and 'B' are .usually -distinguished. In phase 'A' a very f
