Numerical model of electrode induction melting for gas atomization

Numerical Model of Melting Problems

In the present study, a finite volume method is employed to model the advection-diffusion phenomenon during a pure substance melting process. The exercise is limited to a benchmark problem consisting of the 2D melting from a vertical wall of a PCM driven by natural convection in the melt. Numerical results, mainly the temporal evolution of average Nusselt number at the hot wall and the average ...

Atomization Uniformity in Gas -

There are two important aspects to good injector performance in rocket engines—the atomization performance (droplet size and distribution, for example) and uniformity of operation (even distribution of droplets in time and space). In general, both of these aspects are affected by the geometry and operating conditions of the injector. In studying atomization performance, prior work has largely f...

Numerical Models for Viscoelastic Liquid Atomization Spray

Atomization spray of non-Newtonian liquid plays a pivotal role in various engineering applications, especially for the energy utilization. To operate spray systems efficiently and well understand the effects of liquid rheological properties on the whole spray process, a comprehensive model using Euler-Lagrangian approaches was established to simulate the evolution of the atomization spray for v...

Hybrid Gas Atomization for Powder Production

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
