STABILITY OF BUOYANCY-INDUCED FLOWS ADJACENT TO A VERTICAL ISOTHERMALSURFACE IN COLD PURE WATER - NEUTRAL STABILITY IN THE RANGE SS-THAN-OR-EQUAL-TO-R-LESS-THAN-OR-EQUAL-TO-0.1515

Numerical solutions of the hydrodynamic stability equations for buoyan cy-induced flows adjacent to a vertical, planar, isothermal surface in cold pure water have been obtained for various values of the density extremum parameter R = (T-m-T-infinity)/(T-0-T-infinity). The present numerical study yields neutral stability results for the region of the flows corresponding to 0.0 less than or equal to R less than or equal to 0.1515, where outside buoyancy force reversals arise. Also, it inc ludes the relative stability of the three previously predicted multipl e, steady-state solutions of the flow. When the stability results of t he present work are compared to the previous experimental data, the nu merical results agree well qualitatively.
