“…The modeling of reaction jets has been undertaken using either locally homogeneous flow (LHF, Chen and Faeth, 1983;Chan and Shen, 1990), two-fluid model (TFM, Zhang et al, 2002) or the multifluid model (MFM, Chan and Abou Ellai, 1991). Chan et al (1988 reported that the plume dimension predictions, using the locally homogeneous flow (LHF) with probability density function (PDF) approach and the k-e-g turbulence model, were reasonable for the reactive jets.…”

“…The nonlinear equations of imperfect gases, solutes, and solvent of nonideal electrolytic as well as nonelectrolytic solutions were solved by a modified Newton-Raphson iteration scheme using partial molal (or molar) enthalpy, activity coefficient expression, thermodynamic data and chemical potential expressions. 21 The instantaneous scalar thermodynamic properties at each point in the flow correspond to the state reached when injected and ambient fluid at their initial states, having proportions given by the mixture fraction, are adiabatically mixed and brought to thermodynamic equilibrium at the ambient pressure of the flow. Therefore, the scalar thermodynamic properties of the flow were determined, as a function of the mixture fraction (termed as state relationships), by simple adiabatic mixing calculations for given injector exit and ambient conditions and pressure.…”

Gas-liquid jet reactors are widely used in commercial applications such as condensing jets for direct contact feedwater heaters and steam jet pumps, because of their efficient heat-and mass-transfer characteristics. These are also used for the blowdown of primary nuclear boiler systems into a water bath, without releasing fissionable materials into the atmosphere. Reacting jets are of major interest in metal processing and thermal energy sources that involve submerged injection of an oxidizer into a liquid metal bath. The design of gasliquid jet reactors is strongly dependent on the plume dimensions and the flow pattern in the liquid phase. In the present review paper, a critical analysis of the published literature on the fluid dynamics and heat transfer for gas-liquid jet reactors has been performed. The analysis has been extended for the empirical, semiempirical, and analytical attempts for the correlations of experimental observations. The published works on the computational fluid dynamics (CFD) simulations have also been critically analyzed. A comprehensive discussion has been presented and an attempt has been made to arrive at a coherent theme that clearly describes the present status of the published literature. Furthermore, recommendations have been made that are expected to be useful for the design engineers as well as researchers, to improve the reliability in the design of this important class of reactors.
