In this study, we numerically simulated nitrogen injection for oil reservoir development and explored the oil–gas two-phase flow model its finite difference solution method. A mathematical incorporating both gas phases was constructed, which fully considered compressibility along with Darcy's law gravitational effects in flow. The discretized using method, implicit pressure explicit saturation (IMPES) approach employed to obtain numerical solution, analyzing variation patterns of saturation,...
Spontaneous combustion of residual coal in the goaf is one main disasters mines. Understanding law spontaneous can effectively prevent mine fires. This paper establishes a dynamic evolution model overburden caving and porosity using PFC numerical simulation software, compares analyzes changes zone at advancing distances 50m, 70m, 100m. The results show that when working face advances 100m, decreases from 0-0.6 to 0.16-0.3. range on return air side expands 42m-50m 39m-61m, inlet side, it 0...
Influenced by the complex environment and nature of process materials in goaf, prevention control spontaneous combustion coal (CSC) deep part goaf were facing many difficulties. To investigate performance ultrasonic atomized aerosols, a series atomization experiments conducted using self-developed device. The main conclusions are as follows: under same conditions, particle sizes several inhibitors (except PAS-W) concentrated <8 μm range, with content more than 88%, indicating that aerosol...
