Stability and measurements of fluid and thermal transport in vertical buoyancy induced flows in cold water
Abstract
In pure water, the density entremum at 4 C is well known. The presence of a density extremum in the flow field was found to greatly modify the condition and the basic mechanisms of hydrodynamic instability. Buoyancy force reversal in the base flow further complicates the stability. However, there is no similarity solution for the base flow, with a reversal, for the uniform flux condition. Similarity results only when the quiescent medium is at the temperature condition at which the extremum occurs. However, for an isothermal surface a similarity base flow solution also exists for other ambient temperature conditions. The extremum temperature is both salinity and pressure dependent. An additional parameter q(s.p) in the formulation of base flow and stability equations represent this dependence. The disturbance vorticity and energy equations in linearized form were integrated numerically for two conditionsuniform flux and isothermal surface in ambient water at the temperature condition at which the extremum occurs.
