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.

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 ...

Estimation of fan pressure ratio requirements and operating performance for the National Transonic Facility [PDF]

The National Transonic Facility (NTF), a fan-driven, transonic, pressurized, cryogenic wind tunnel, will operate over the Mach number range of 0.10 to 1.20 with stagnation pressures varying from 1.00 to about 8.8 atm and stagnation temperatures varying ...

The pressure confined wind of the massive and compact superstar cluster M82-A1

, 2007
The observed parameters of the young superstar cluster M82-A1 and its associated compact HII region are here shown to indicate a low heating efficiency or immediate loss, through radiative cooling, of a large fraction of the energy inserted by stellar ...

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.

Joule Heating Effects on MHD Natural Convection Flows in Presence of Pressure Stress Work and Viscous Dissipation from a Horizontal Circular Cylinder

Journal of Applied Fluid Mechanics, 2014
The effects of joule heating on MHD natural convection flow from a horizontal circular cylinder along the outer surface from the lower stagnation point to the upper stagnation point in presence of pressure stress work and viscous dissipation is ...
