Study on the Centrifugal Atomization Process of Molten Slag with the Coupled Algorithm of Three-Dimensional SPH-FEM

Abstract:

The SPH method was introduced to simulate the centrifugal atomization process between molten slag and rotary disc since the traditional method based on grid cannot effectively solve the large deformation problem. Coupling the SPH method with FEM was realized through the coupled algorithm based on penalty function. The effectiveness of coupling algorithm used for calculating the centrifugal atomization process was affirmed. Under the condition that speed of rotary disc and molten slag flow are 1500rpm, 0.1m/s, respectively, the speed of molten slag particles that are directly colliding with the rotary disc is in a range from 2.5m/s to 3.0m/s as soon as that of molten slag particles disturbed by stress wave is in a range from 0.25m/s to 0.8m/s with the characteristics of volatility. This study is helpful for optimizing atomization process design and energy-saving efficiency.
