This paper focused on numerical computation in solid conveying theory,non-plug solid conveying theory was introduced to improve the precision of plug solid conveying theory and finite element method was used to solve the model.

Analyzed the flow characteristic of plastic particles in feeding zone while screw operating, introduced the basic calculation method on the theory of plug flow solid conveying and unplug flow solid conveying and taken the pressure formula.

This paper studied the plug flow characteristic of Medium-Consistency pulp suspensions in the pipeline based on the high pressure gas delivery and virtual instrument technology,and measured the hydrodynamic parameters of MC pulp under the different external conditions.

Study on secondary combustion chamber air-inlet scheme of unchoked solid rocket ramjet;

Numerical computation of after burner flow in unchoked solid rocket ramjet;

The altitude characteristics and velocity characteristics of three types of solid ducted rocket, which are choked solid ramrocket with fixed mass flow rate of fuelrich gas generator, unchoked one and the one working under fixed mass ratio of air to fuel, were numerically studied.

A non-close,non-block and low-overhead checkpointing algorithm is proposed for computational grid service system which provides computation function for mobile agents.

Based on P2P and half-sync/half-async architecture, we implemented the streaming media server, which uses EPOLL as the asynchronous event notification facility and handled the network events in a non-block way.
