Water maser polarization observations in the precessing jet of W43A have revealed that it is magnetically collimated. Here we present a detailed description of the physical properties of the water maser environment in the jet. We discuss the maser saturation level and beaming angle as well as the intrinsic temperatures and densities. Additionally, we show that the polarization angle of the stro...

Unconventional machining processes (communally named advanced or modern machining processes) are widely used by manufacturing industries. These advanced machining processes allow producing complex profiles and high quality-products. However, several process parameters should be optimized to achieve this end. In this paper, the optimization of process parameters of two conventional and four adva...

Physical properties of breads during baking were measured using three different heating modes of microwave plus infrared (MIR), microwave plus jet impingement (MJET) and jet impingement (JET) in two different commercially available microwave combination ovens. Breads baked in JET oven were significantly different from the breads baked in other ovens with respect to their specific volume and moi...

The transitional Reynolds numbers for different patterns are available and a proposed transitional map is also provided in this paper. The transition of falling-films on flat tubes is studied in this work. Water and ethylene glycol are used as working fluids, for falling-film experiments conducted under adiabatic conditions, without an imposed vapor flow. The flow patterns are recorded using a ...

As an alternative to ski jumps, deflectors can be implemented on spillways to generate free jets. They guide, up to a certain limit, the jet to an achieved location onto the plunge pool surface, and furthermore enhance the process of jet disintegration. The present research addresses the following aspects, derived from physical model tests: (1) length and shape of the jet black-water core and f...

Drug delivery through jet-injection opens the doors to very rapid drug dispersion by eliminating the need for needle sterilization. With this comes the need for a continuous flow of fluids from a large reservoir, currently not available to the single-piston drug delivery systems. A two-piston system in a jet injector enables the use of a cyclic motion of pistons to drive the injected fluids, as...

Water jet and Abrasive Water Jet (WJ/AWJ) are manufacturing technologies suitable for particular operations (cutting, milling, turning, surface treatment, etc.) on different types of materials. The use of water (or water mixed to abrasive in AWJ technology) allows working both soft and hard materials without damaging the interested area of the workpiece. In previous studies the authors have jus...

This paper reports on the results of experimental investigations on the performance of a jet pump operated under selected primary flows to optimize the related parameters. For this purpose a two-phase flow jet pump was used employing various profiles of nozzles as the primary device which was designed, fabricated and used along with the combination of mixing tube and diffuser. The profiles empl...

The eeect of axial and azimuthal forcing on the spreading and mixing characteristics in the near eld (x=D < 13) of a cooowing, turbulent (Re > 2000) water jet is studied by means of planar, laser induced uorescence (PLIF) visualizations. Measurements of both the initial spreading rate of the jet and the decay of the concentration along the centerline of the jet show a marked increase in the mix...
