  • Numerical investigation of the influences of mixing ...

    2014-11-17 · In studying the influence of the mixing chamber length on the performance of the steam ejector, the primary, the secondary and the back pressure are fixed at 600 kPa, 15 kPa and 40 kPa, respectively. The mixing chamber length is changed without changing the convergence angle and the outlet diameter of the mixing chamber.

  • Numerical investigation of geometry parameters for …

    2009-4-1 · Converging angle of mixing section: The ejector performance is very sensitive to θ especially near its optimum value, and a slight variation of θ has a great influence on the ejector performance. When the NXP is within its optimum range, the optimum converging angle is in the range of 1.45–4.2° with the primary flow pressure from 4.5 to 6 bar.

  • Effects of Focus Geometry on the Hard Rock-Cutting ...

    Abrasive waterjets are being increasingly used in civil engineering for rock and concrete cutting, particularly for the demolition or repair of old structures. The energy of an abrasive waterjet is primarily provided by the accelerated abrasive. The momentum transfer during mixing and acceleration determines the abrasive velocity, which affects the cutting performance.

  • Effect of Rotation and Revolution on Performance of Blade ...

    In this study, flow structures and mixing performance in a blade-free planetary mixer, which combines rotation and revolution motions inside a cylindrical vessel, are numerically investigated. Flow fields in the mixer vessel are simulated in a single rotating reference frame with various revolution speeds and a fixed rotation speed. The mixing process is investigated by a Lagrangian particle ...
