The Hydrodynamic Tunnel of I.M.G.: Former and Recent Equipments
(The American Society of Mechanical Engineers (ASME), 1990)The I.M.G. Hydrodynamic Tunnel is described in its initial state and with successive equipments that improved its performances. Particular attention is given to the recent nuclei control system. -
Control of Surface Tension Flows: Instability of a Liquid Jet
(The American Society of Mechanical Engineers (ASME), 1990)A technique of controlling surface tension flows using thermal radiation is proposed. This method takes advantage of the dependence on temperature of the surface tension forces to produce the ... -
Intermittency and Length Scale Distributions in a Plane Turbulent Plume
(The American Society of Mechanical Engineers (ASME), 1990)Previous studies have shown that normalized Reynolds shear stress and turbulent heat fluxes in asymptotic plane turbulent plumes are significantly higher than in asymptotic plane turbulent jets. ... -

A Generalized Approach on Equilibrium Theory of Cavitation Nuclei in Liquid-Gas Solutions
(The American Society of Mechanical Engineers (ASME), 1990)The availability of a single bubble-droplet system is derived from energy conservation and the principle of entropy. The equilibrium and critical conditions are determined by minimizing the ... -
Flow Through an Orifice From a Transverse Stream
(The American Society of Mechanical Engineers (ASME), 1990)Flow through orifices has been investigated thoroughly and a large amount of information on discharge coefficients and losses is available. Almost all of these results presuppose that the ... -
