According to the rock failure damage theories and gas-solid coupling method,the RFPA2D-GasFlow soft code in combination with the stress distribution in coal body and process and the result of gas outburst was applied to the analysis of the effect of ground stress on gas outburst process.

For air spring vibration-insulator design in this study,the finite element method is employed to resolve such problems as gas-solid coupling and nonlinearity.

To improve the predictive accuracy of bubble concentration distribution,numerical study of upward turbulent channel flows laden with microbubbles is carried out and the fluid-bubble two-way coupling interaction is considered.

A direct numerical simulation (DNS) technique based on two-way coupling was developed to study the influences on gas-phase jet by dispersed particles in a two-phase turbulent jet.

The vortex pairing in 2D gas-solid mixing layer is simulated considering the two-way coupling model and the interactions among the particles through the fluids.

Control and synchronization of time-delayed bidirectional coupled chaotic systems;
