• Consideration is :iven to the stabilitv characteristics of two-dimensionalwall plumes arising from a line source of heat positioned at the edge of verticalor inclined surface. The disturbance equations are solved numerically on thebasis of the linear stability theory for a Prandtl number of 0.7 (air). Two unstablemodes exist but no loop appears in the neutral stability curve as a result of merg-ing of their modes. The effect of varying the angle of the surface inclinationfrom downward-facing to upward-facing is to increase instability of the flow.The balance relation of disturbance energy shows that buoyancy forces havedestabilizing effects in both modes.
