Abstract

Wave instability of natural convection boundary layer flow adjacent to inclined surfaces is analyzed by a linear theory. The effects of the nonparallelism of the main flow and thermal fields are taken into account in the analysis. Neutral stability results for Prandtl numbers of 0. 7 and 7. 0 are presented for upward-facing heated surfaces, for angles of inclination ranging from 0 to 90 degree . These results are compared with available analytical wave instability results for small angles of inclination. They are also compared with analytical vortex instability results and with available experimental data.
