Heat and mass transfer in annular liquid jets: I. Formulation
Heat and mass transfer phenomena in annular liquid jets are analyzed at high Reynolds numbers by means of a model derived from the governing equations that takes into account the eects of surface tension and boundary conditions at the gas± liquid interfaces and the large dierences between the thermal and mass diusivities, densities, dynamic viscosities, and thermal conductivities between gas...
متن کاملHeat and mass transfer in annular liquid jets: II. g-jitter
The eects of g-jitter on heat and mass transfer in underpressurized, annular liquid jets are analyzed numerically as a function of the amplitude and frequency of the gravitational modulation by means of a mapping technique that transforms the timedependent geometry of these jets into a unit square and a conservative ®nite dierence method. It is shown that the pressure coecient, gas concentra...
متن کاملBreakup of Liquid Jets
For fundamental analysis of the transport of mass or heat in a dispersed system, accurate knowledge of behavior of jet is prerequisite. For generation of high interfacial area breaking of liquid jet in to small droplet is necessary. Liquid jet breakup is a complex phenomenon and dependent on many factors like velocity of jet, pressure difference, geometry of nozzle, temperature of both fluid, p...
متن کاملPhysics of liquid jets
Jets, i.e. collimated streams of matter, occur from the microscale up to the large-scale structure of the universe. Our focus will be mostly on surface tension effects, which result from the cohesive properties of liquids. Paradoxically, cohesive forces promote the breakup of jets, widely encountered in nature, technology and basic science, for example in nuclear fission, DNA sampling, medical ...
متن کاملElectrospinning of liquid jets
A very thin liquid jets can be obtained using electric fields. The electrically-driven bending instability of the jet enormously increases the jet elongation path and effectively leads to its tinning by very large ratios and can be used to produce nanofibres. The mechanism of electro-thinning of liquid jets, discovered almost one century ago, is yet not fully understood. In the following study ...
