Study on droplet transfer behavior and porosity defects in narrow-gap laser–arc hybrid welding of titanium alloy

Hanjie xuebao
In narrow-gap laser–arc hybrid welding, the droplet transfer behavior indirectly affects the formation of porosity defects by influencing the molten pool disturbance and keyhole stability.

Jumping droplet condensation in internal convective vapor flow

, 2022
© 2020 Condensation is an important process in the Rankine cycle that significantly affects overall efficiency. Condensate typically forms a liquid film due to the high surface energy of industrial condenser materials; by engineering the condenser ...

Numerical Investigation of the Main Characteristics of Heat and Mass Transfer while Heating the Heterogeneous Water Droplet in the Hot Gases

EPJ Web of Conferences, 2016
The processes of heat and evaporation of heterogeneous water droplet with solid (by the example of carbon) inclusion in hot (from 800 K to 1500 K) gases were investigated by the developed models of heat and mass transfer.

Heat transfer to bouncing droplets on superhydrophobic surfaces

International Journal of Heat and Mass Transfer, 2019
Abstract This study experimentally and theoretically investigates the dynamics and heat transfer to impinging water droplets on superhydrophobic surfaces heated below the boiling temperature. Different from impingement on hydrophilic substrates, the droplets rebound from the surface after the spreading and retraction stages. Experiments are performed

Effect of droplet characteristics on heat transfer of mist/air cooling in a pin-finned channel

, 2019
Effects of droplet characteristics of mist/air cooling on heat transfer for three pin-fin structures are investigated. The round-tip pin-fin structure is newly proposed with partial detachment from one endwall with a round-shaped tip structure.

Characteristics of droplets formed on the outer surface of the rotating packed bed [PDF]

EPJ Web of Conferences
A rotating packed bed (RPB), as a device for mass transfer enhancement, can be divided into three main parts. An eye of a rotor, a packing, and an outer cavity.
