Solar Evaporation System Using Spray Pipe Method [PDF]
Evaporation of water using a spray pipe is required to expand the contact between hot air and water surface so that the rate of evaporation of water becomes faster. Salt production in the case of solar evaporation may take weeks to obtain salt.

Numerical investigation of the effect of different parameters on emitted shockwave from bubble collapse in a nozzle [PDF]
Cavitation can be extremely beneficial for the first spray breakup and to enhance atomization quality. An Eulerian/Lagrangian approach using Reynolds average Navier-Stokes (RANS) and bubble dynamic equations was used for the prediction of cavitation ...

Molecular Dynamics Study of the Sonic Horizon of Microscopic Laval Nozzles [PDF]
A Laval nozzle can accelerate expanding gas above supersonic velocities, while cooling the gas in the process. This work investigates this process for microscopic Laval nozzles by means of non-equilibrium molecular dynamics simulations of statioary flow, using grand canonical Monte-Carlo particle reservoirs.

Effect of Nozzle Curvature on Supersonic Gas Jets Used in Laser-Plasma Acceleration [PDF]
Supersonic gas jets produced by converging-diverging (C-D) nozzles are commonly used as targets for laser-plasma acceleration (LPA) experiments. A major point of interest for these targets is the gas density at the region of interaction where the laser ionizes the gas plume to create a plasma, providing the acceleration structure.
