Abstract : A analytical study of laminar and turbulent jet mixing in a straight parallel wall channel was made using three different initial velocity profiles. The system of governing equations describing the flow was solved using a implicit finite-difference technique. The governing equations were reduced to a set of linear algbraic equations that were solved simultaneously on a digital computer. The development of the axial velocity profiles and the jet mixing spreading rates for the three cases are compared. For the laminar cases, the momentum flux increased when a negative pressure gradient was present. For the turbulent jet mixing cases, the boundary-layer growth is laminar, and the analysis is restricted to the initial region. (Author)
