An attempt has been made to form a qualitative correlation between the nozzle shape and issuing jet shap茅. The following points can be made: 1. (i) The major requirement of a nozzle is the efficient conversion of potential energy to kinetic energy. This is best achieved by a sudden, ...
Large-eddy simulations of chevron jet flows with noise predictions Hybrid large-eddy type simulations for chevron nozzle jet flows are performed at Mach 0.9 and Re = 1.03 × 10 6. Without using any subgrid scale model (SGS... X Hao,PG Tucker,S Eastwood - 《International Journal of Heat ...

It is proven that the ducted propeller has a fixed ratio between the velocity through the nozzle and the velocity downstream. This is comparable to the behavior of a waterjet, and consequently different from an open propeller. Thrust of the propulsion unit can be determined from a direct ...
Analysis of turbulent underexpanded jets. I - Parabolized Navier-Stokes model, SCIPVIS A new computational model (SCIPVIS) is described which predicts the multiple-cell wave/shock structure in underexpanded or overexpanded turbulent jets. SCIPVIS solves the parabolized Navier-Stokes jet-mixing ...
Elbow-Jet Air Classifier • Particle classification Functional • Simultaneous fine and coarse particle classification.• Capable of classifying particles of very small size range (0.5–10 μm). [170] Froth flotation devices • Separation Spatial and temporal • Very rapid process (1 s vs....
(Fig.2b). In detail, a polymer solution is placed into the capillary tube and then a high-voltage electric field is applied between the tip of the tube and collection plate. The polymer solution will be drawn out of the tip and form a jet of fluid in the form of a twisted Taylor ...
ElectroHydroDynamic Atomization (EHDA) is a physical process of liquid dispersion to fine droplets by electrical force and shear stress on the liquid surface. Under these forces, the jet at a capillary nozzle outlet elongates and breaks up into fine droplets at its end. EHDA technique allows produ...
SSE forms a 3D structure with the layer–by-layer extrusion of semi-solids through a nozzle using air pressure or screw gear rotation [143]. In FDM, on the other hand, the filaments of the starting material are softened and melted using a heated nozzle. The 3D object is then built up ...
The glass industry is part of the energy-intensive industry posing a major challenge to fulfill the CO2 reduction targets of the Paris Climate Agreement. The segments of the glass industry, e.g., container or flat glass, are quite diverse and attribute to different glass products with different...
