which, can be called the ‘secondary fluid’ (S), can be entrained into the mixing chamber. The primary fluid’s expanded wave was thought to flow and form a converging duct without mixing with the secondary fluid. At some cross-section along this duct, the speed of secondary fluid rises to sonic value (iii) and chokes. This cross-section was defined by Munday and Bagster as the ‘effective area’.
