Experimental investigation of helium injection at a low downstream angle into supersonic flow
… were performed with single, sonic, helium jets at downstream angles of 15° and 30° relative to the free stream to determine their mixing, penetration and total pressure loss when injected into a supersonic air cross flow. From this information, the performance of these jets as fuel …

A comprehensive analysis of natural gas direct injection and of mixture formation in spark ignition engines
… Firstly the theoretical background of supersonic underexpanded jets is summarized (section 2.1), followed by a literary review of previous investigations regarding the numerical simulation of gaseous direct injection in internal combustion engines (section 2.2). In section 2.3, the test case of a …

CFD simulation of flow fields associated with high speed jet impingement on deflectors
… used to analyze the formation of under-expanded jets and to investigate the three-dimensional flow field associated with the impingement of free jets onto stationary deflectors. This investigation was performed to develop a verified modeling ability for such problems. Predictions were compared …
