Overstability in an Infinite Liquid Layer under Simultaneous Surface Tension, Buoyancy and Shear Ef, Pearson (1958), Scriven and Sternling (1964) and Nield (1964) among others. The principle of exchange of stability holds for Rayleigh-Bénard problems. Conversely, for Bénard-Marangoni problems, the liquid layer may exhibit overstability. Linear analysis of overstability is much more difficult to p

A Mathematical Description of the Critical Heat Flux as a Non-Linear Dynamic Instability, field adjacent to the heated wall. A set of three non-linear differential equations model the dynamics of the localized void fraction, bubble number density and vapor velocity. The boiling crisis at the critical heat flux is described as a dynamic transition caused by the competition of bubbles coa

Study on the Effective Parameters for the Geysering Period,column, having either a zero or very small inlet velocity, increases bubble generation after boiling, thereby decreasing the column’s hydrostatic head. This reduction in head subsequently decreases saturation temperature and it allows more bubbles to be generated. Thus in certain conditions, they ca

Dynamics of a Reduced Model of Two-Phase Flow in a Boiling Channel,ituted a part of a steam engine. Particular features of the system were that the boiling tube was coiled, and that the externally supplied heat was generated by an exothermic chemical reaction. The reactant supply was controlled so as to maintain an exit temperature of 540°C at an operating pressure

Bifurcations in Two-Phase Flames,ually breaks up into small droplets that evaporate, ignite and burn. The Diesel engine provides a practical example of such a process. The interaction of droplets and sprays with a gaseous phase are particularly complex, if the gaseous phase is a flame that is self-sustained by gaseous fuel and oxid

Application of Laser-Induced Thermal Lens Oscillation to Concentration Control in Solvent Extractioa laser beam and organic solution. A concentration of a solute in organic solutions was determined by finding bifurcation point which was observed in laser-induced thermal lens phenomena. The concentration determination was successfully demonstrated for uranyl nitrate extracted with 30% tri-.-butyl
