The effect of a longitudinal surface temperature gradient on the extension of a laminar boundary layer of a gas
Abstract
The paper is concerned with the problem of the stability of a subsonic laminar boundary layer of a gas on a flat plate whose surface temperature is a function of the longitudinal coordinate. The problem is reduced to that of analyzing the stability of a solution to linearized Navier-Stokes equations written for a compressible thermal boundary layer of a gas with variable physical properties. The coefficients of the linearized system of equations are determined from the solution of non-self-similar equations of a stationary thermal boundary layer. The linearized boundary value problem is solved numerically using a refined version of the orthogonalization method; the stationary problem is solved using the Kepler method.
