Parallel calculational methods were used to analyze incompressible turbulent flow through hydraulic machinery. Two parallel methods were used to simulate mulate the complex flow field. The space decorrposition method divides vides the computational domain into several sub-ranges. Parallel discrete e...

To simulate the phenomena in the mold region of continuous casting by coupling fluid flow and solidification, a three-dimensional mathematical model has been developed based on the K-ε turbulence equations and the SIMPLER algorithm. A pseudo source term was introduced into the energy equation...

A method to model and analyze the hybrid systems is presented. The time to. be considered in the plant is taken as an explicit parameter through the constrained predicated net (CPN). The CPN' s basic structure is a Petri net with predicated transition. All components of the net are expressed by anno...

With the rapid development of electricity production, SO2 from coal-fired power stations causes severe air pollution problem. In 1997, the SO2 emitted from thermal power plants reached 7.,0 Mt, accounting for about 33% of the national emissions. At present and in the future, th...

There has been an increasing interest in integrating decision support systems (DSS) and expert systems (ES) to provide decision makers a more accessible, productive and domain-independent information and computing environment. This paper is aimed at designing a multiple expert systems integrated dec...
