Modelling of the injection of hot liquid sprays into a closed vessel

Kubie, J

Abstract

An experimental and theoretical study recently investigated the transient processes that occur when hot liquid spray droplets are suddenly injected into air contained in a closed chamber [1]. The analysis gathered all important parameters governing droplet heat transfer in a single dimensionless group, denoted by K2. The work has been extended by redefining K2, and introducing a new dimensionless group KN2, and by using helium as the surrounding gas. The dimensionless group KN2 is, to a first approximation, independent of all parameters investigated in the present work, including the properties of the surrounding gas, and approximately equal to 0.12. The dimensionless group KN2 =0.12 should be used instead of the Nusselt number as the primary dimensionless group in analysing the heat transfer performance of spray injection nozzles in closed chambers.
