• Stability of a Natural Convection Flow

抄録

Linear stability theory is applied to laminar natural convection plumes arising from a point heat source for Prandtl numbers of 2 and 0.7 (air). The axisymmetric steady plume which has a boundary-layer structure is used as the basic flow. The stability equations which include the effect of velocity-temperature disturbance coupling are numerically solved for both axisymmetric and non-axisymmetric disturbances. The axisymmetric mode is found to be stable. The non-axisymmetric mode n=1 is found to be unstable but n=2 stable, where n is the azimuthal wave-number of the non-axisymmetric disturbance.
