The stability of the axisymmetric boundary layer on a circular cylinder
Abstract
The stability of the laminar boundary layer on a circular cylinder whose axis is aligned with the direction of the mean flow is determined. A two-equation local nonsimilarity method is used to find the mean velocity profiles at different axial locations. The Compound Matrix Method, which prevents parasitic error without using an orthonormalization procedure, is used for the stability calculations. This method has several advantages, particularly when working in single precision arithmetic. The numerical results of the axisymmetric stability calculations show the effect of transverse curvature. A comparison is made between the axisymmetric results and flat plate calculations. The effect of wall temperature on the profiles of the mean velocity is also shown.
