Abstract
The unique characteristics of high-speed liquid fuel jets suggest that they have the potential to be applied to high performance diesel engines, SCRAM jets and other combustion applications where small combustion residence times are required. When a liquid jet is injected at supersonic speed, with respect to the surrounding medium, a bow shock wave is produced. The ability of such jets to increase atomisation rates and decrease ignition times has led to interest in the liquid jet head - bow shock region. The use of CFD to study this region is advantageous as experimental studies are unable to take many measurements without being intrusive. This paper investigates the effect of the dynamic jet shape on the bow shock stand-off distance and shape using contemporary CFD methods. The shock wave characteristics in the shock layer are also presented.
