Abstract
A numerical simulation of two-dimensional jets was carried out by the SOLA methods. The two-dimensional jets were discharged from a slit in a wall at Reynolds numbers less than 50. The difference between the calculated flow fields and those of the Bickley jet is due to the non-uniformity of pressure field near the jet exit of the wall. The jet spreads faster than the Bickley jet. The decay of streamwise velocity on the center-plane is more rapid than that of the Bickley jet. The streamwise velocity profile is different from that of the Bickley jet, and a reversed flow is generated in the outer part of the jet. Integrals of momentum and pressure were calculated on a control surface to confirm the momentum conservation law. The integral of momentum is not constant, and balances to the integral of pressure, in the streamewise direction.
