Jet Impingement on two flat plates with an angle between them has been experimentally and Numerically studied at different flow and geometrical conditions. The numerical simulations were performed by the solution of Navier-Stokes equations with a kE model. The stagnation pressure ratio (p, I p.) was varied from 1.2 to 3. Thus, the Reynolds number based on the nozzle width (b) was ranged from 4.5 x lo4 to 8.3 x 10' . The distance between the center of the two plates and nozzle exit plane (hlb) was changed from 5 to 60. The angle between the two plates (0) was varied from 50" to 180' . Pressure distributions along the two plates were compared with those of a free jet. Also, results have been compared with those obtained from the numerical solution. It is concluded that the jet flow behavior and pressure distributions are more sensitive to the initial stagnation pressure, the impingement distance than those obtained with varying the angle between the two impingement plates. Comparison of the predicted behavior of the jet with those obtained from experimental results gives a good agreement. a $, I j L,& &>I+ ~~ &kY Jic ( & ) *Id1 &2 ' j k d +&, + L l j> &+I & ~ b + l & ~ ~ & L J ! p + q ~ Z .
