Computation of nozzle flow fields using the PARC2D Navier-Stokes code [PDF]

Supersonic nozzles which operate at low Reynolds numbers and have large expansion ratios have very thick boundary layers at their exit. This leads to a very strong viscous/inviscid interaction upon the flow within the nozzle and the traditional nozzle ...

Effect of melt tip taper angle on atomization process in gas atomization

Fenmo yejin jishu
Atomizing nozzle is the core component of the gas atomization process, which structural parameters, especially the melt tip taper angle of the delivery tube, have the great impact on the gas atomization results.

An experimental investigation on the role of the operating time of the mist device on the thermal performances of a water-sprayed air-cooled condenser and on the energy consumption of the cooling system

International Journal of Thermofluids
Water spraying upstream of an air-cooled condenser enables high heat dissipation. Meanwhile, a good control on the spray-heater parameters is crucial to avoid excesses of water and heat transfer destruction.
