An unsteady numerical simulation method was used in order to explore more efficient atomization methods for liquid fuel scramjet combustors and study the influence of different shock wave incident positions on characteristics kerosene crossflow. The wedge compression surface generate wave, position jet controlled by changing angle surface. inlet Mach number 2.01; total temperature 300 K, moment...

A compact static mixer for gas–liquid dispersion in pipelines is studied this paper with a Reynolds averaged two fluid model approach. procedure based on the lumped parameter solution of population balance applied to obtain bubble Sauter mean diameter needed interphase forces. The gas distribution pipe analyzed different operative conditions and efficiency assessed terms homogeneity section, lo...

conveying velocity, pipe wear, and particle degradation. An experimental study has Yuji Tomita addressed the characteristics of swirling flow pneumatic conveying (SFPC) for the Professor, total pressure drop, solid flow patterns, power consumption, and additional pressure Department of Mechanical Engineering, drop. Polystyrene, polyethylene, and polyvinyl particles with mean diameters of 1.7, K...

Cryogen spray cooling allows removing large amounts of heat in short periods of time. Previous investigations have shown that stainless steel wire meshes placed between spray nozzle and target surfaces effectively increase uniformity in lateral heat extraction while reducing cooling efficiency. In this study we used phase Doppler particle analysis to assess the effect of a wire mesh on the diam...

For developmental competence of porcine embryos in vitro, it is important to improve the culture environment. The present study was performed to evaluate four different culture systems for in vitro matured porcine oocytes following intracytoplasmic sperm injection (ICSI); drop, well and two sizes of the well of the well (WOW) systems (500 and 1,000 microm in diameter). The cleavage rate on Day ...

Spray atomization is a common process found in different industries, where sprays under high injection pressure are widely recorded in the literature. Nonetheless, research on spray breakup mechanism under low pressure in pharmaceutical industry is still relatively rare. Numerical model in the Lagrangian approach was modified for simulating the spray formation from a nasal spray device in the c...

The viscosity of adiponitrile waste liquid is as high 1000 cp. It challenging to spray and atomize the normally. Based on coaxial three-channel pneumatic atomizer, a two-stage supersonic steam atomizer proposed in this paper, atomization process simulated by Fluent software. Compared with traditional simulation method, Volume-of-Fluid Discrete-Phase-Model (VOF-DPM) bi-directional coupling model...
