Solution of the equations of an unsteady boundary layer
Abstract
A number of nonselfsimilar problems of an unsteady boundary layer are considered. A substitution of variables is proposed which makes it possible to increase the time step by approximately an order of magnitude, leading to a considerable saving in computational time. An analysis is presented of the effect of various parameters (acceleration, pressure gradient, gas composition, injection, and velocity dependence of viscosity) on friction and heat flux to the wall. The numerical results make it possible to analyze errors which arise when the model of local selfsimilarity is used in the unsteady case.
