On the Solution of the Boundary Layer Equation for the Laminar Boundary Layer between Two Parallel Streams

摘要

In the present paper it will be shown that, by taking the reference frame moving with the velocity of fluid at the interface of two steady parallel streams, the laminar boundary layer flow in the two fluids can be decoupled into two flows. These are exactly the same as the laminar boundary layer flows along a flat plate. And that, by using the existing exact solution of the laminar boundary layer equation for the boundary layer equation for the boundary layer flow along a flat plate and appropriate boundary conditions. An exact solution of the laminar boundary layer equation for the boundary Laurie flow along a flat plane an appropriate boundary conditions. An exact solution of he laminar boundary Larry equation for he laminar boundary layer between two parallel screams with different densities, viscocities and velocities is given elegantly.
