DEVELOPMENT OF A MATHEMATICAL MODEL FOR THE STUDY OF THE DYNAMICS OF CHANGING THE CHARACTER OF INTERACTION OF AIR FLOW AND DUST FLOW AT COLLISION WITH A DUST ASYLUM WALL
Abstract and keywords
Abstract (English):
The article deals with a mathematical model to study the dynamics of changes in the nature of the interaction of air flow and dust flow in a collision with a dust intake wall. Mathematical modeling of the behavior of air flows on the territory of the port open coal warehouse will give an idea of the dynamics of the behavior of coal dust. This will allow more accurately take into account all the meteorological features of blowing: wind speed, altitude distribution of velocities, turbulence, various geometric parameters of warehouses. As a result of the numerical implementation of this model by the control volume method, we are able to analyze the structure of the flow flowing around the coal warehouse and draw conclusions about the nature of dust formation, separation of coal dust particles, displacement of coal dust particles.

Keywords:
coal dust, open coal warehouse, bulk cargo dusting, mathematical model
