• The secondary jets induced by double laminar steady plane jets of an incompressible fluid in the domain between jets is investigated. A full Navier-Stokes equation is solved numerically for this problem by using the finite difference approximation method. The general features of the secondary flow by jets are as follows. (i) The more the outlet velocity increases, the farther the centers of two vortexes leave the wall. (ii) The change of the velocity profiles is very remarkable between the wall and the centers of the vortexes. (iii) The maximum velocity of an induced flow to the wall is 30% of the outlet velocity. (iv) The profile of the vorticity distribution is hardly influenced by the outlet velocity, but the vorticity is much influenced by it. And the experimental data are in good agreement with the numerical solutions.
