    2009-6-25 · Once Nozzle A2 was tested and it was confirmed that the triboelectric method was an accurate way of measuring the jet boundaries of a gas–liquid jet, Nozzle A1 was tested using the triboelectric probes under the same conditions (1.5 wt.% ALR, W L = 0.0667 kg/s) to compare the effect of nozzle geometry on jet boundaries.

The effect of the nose-piece shape on the flow field under the MB die was investigated experimentally by Tate and Shambaugh [21] and theoretically by using CFD simulations by Krutka and Shambaugh [24–26].

    2018-8-15 · A compressed air is passed through the nozzle as shown in figure. Here air expands and acquires high velocity due to particular shape of the nozzle. A vortex flow is created in the chamber and air travels in spiral motion along the periphery of the hot side. Then, the rotating air is forced down the inner walls of the hot tube at
