Calculation of a laminar non-self-similar semibounded fluid jet

The dynamic and thermal (for three wall-temperature boundary conditions) problems for a plane laminar incompressible jet propagating along solid plane are analyzed within the framework of boundary layer theory. A numerical method for solving the initial boundary layer equations is proposed, using which the integral condition of conservation for semibounded jets is automatically satisfied in the course of the numerical procedure, and the infinite region of integration is reduced to a finite range. The velocity and temperature fields in the entire region of the flow (for a semibounded jet) are calculated by the method of straight lines.
