“…There is an absence of volcanological data with which to compare the modeled condensation dynamics. The most appropriate comparison available is to experimental data in the engineering field of direct contact condensation (DCC) (Aya & Nariai, 1991; Chun et al., 1996; Hong et al., 2012; Mazed et al., 2018; Meng et al., 2019; Xu et al., 2018; Zhao & Hibiki, 2018). Direct contact heat transfer focuses on the condition when two fluids, typically immiscible, exchange heat directly rather than through a wall or boundary (Zhao & Hibiki, 2018).…”

Both subaerial and submarine explosive volcanic eruptions have the capacity to produce high velocity gas jets where fragmented particle-gas mixtures are ejected with significant inertia inherited from conduit processes (e.g. Woods, 1995). In this jet-thrust region, the particle-laden gas rises and loses kinetic energy through drag, gravitational deceleration, and turbulent mixing with the ambient fluid. Subaerial jet-thrust dynamics have been extensively studied through remote observations, experiments, and numerical simulations (

“…They assumed that the transport modulus and critical steam mass flux at ambient pressure were constant values in the semiempirical penetration length correlation. This correlation has been widely used by other researchers in recent decades, Chun et al [4], Kim et al [5], Sun et al [6] and Meng et al [7]; these have adaptively modified the correlation fit coefficients according to their measurements. Weimer et al [8] suggested a more complex model, which considered the behavior of various liquid fluids, obtaining a correlation of the penetration length that further depended on the density ratio but redefined the value of condensation driving potential.…”

A very efficient method of condensing the steam in various industrial applications is the steam direct discharge into pools with subcooled water. This kind of condensation is known as Direct Contact Condensation (DCC), by providing high heat transfer and mass exchange capacity, the steam condenses quickly. In the past few decades, many experiments have been carried out on the submerged jets of non-condensable gases and pure steam in pools, supplying much information of interest, but efforts are still being made to obtain more information. In particular, the research of steam and non-condensable gas mixtures is of great interest to the chemical, energy, and nuclear industry. Consequently, this study investigates the discharge behavior of air-steam mixtures in a pool with subcooled water by direct visualization techniques using a high-speed camera. To know the behavior of the dimensionless momentum length, tests were carried out considering several initial discharge conditions such as nozzle diameter, percentage of mixture, and flow rates. After image acquisition, a series of complex processing, filtering, and post-processing procedures are applied using a subroutine in MATLAB. The momentum length of the jet was measured and found to be heavily influenced by the nozzle diameter, the jet velocity, and the mixture percentage. A correlation is obtained for the dimensionless momentum length of the horizontal jet that depends on the Froude and Mach numbers.
