The laminar boundary layer flow when a two-dimensional slot jet impinges on a flat plate at some angle is analyzed theoretically. The conservation equations in primitive variables are solved using a finite-difference technique. The computed results at 0 and 90 deg angle of impingement are in perfect agreement with standard solutions available in the literature. The influence of the angle of impingement on the velocity and temperature profiles is studied. The presence of a stagnation point when the plate is not parallel to the oncoming jet is found to affect considerably the local Nusselt number and skin friction coefficient. These parameters attain very large values close to the stagnation point at small angles of impingement. However, far from the stagnation point, they approach values corresponding to a flat plate at zero incidence, irrespective of the angle of jet impingement.
