A New Method of Numerical Integration of the Equations of the Laminar Boundary Layer

摘要

A new method for the numerical solution of the boundary-layer equations is described:This rests in essence on the fact that the equations of steady flow are special cases of the equations of general motion. The velocity profiles are found at successive sections across the boundary layer. Trial values of the velocity are assumed at any section;from these, space'derivatives of the velocity are deduced'by using finite differences, and time derivatives by using the equations of motion. The trial values are theri adjusted to give zero time derivatives of the velocity at the section.
