Load density model with parameters circularly amending is used to draw the calculation of partitioned areas.

By introducing a p-dimensional linear space the parametrized cyclic representations are constructed.

For studying the method of cycle parameters design optimization of turbofan engine,an integrated optimization design model of multirole fighters and turbofan engines is presented,and the computer program based on the model is developed.

In the research,the outputs of different cycle parameters,PCR buffer and reaction volumes are compared.

As an example,the development of a high bypass ratio turbofan engine was used to demonstrate how the constraints restrict design cycle parameters.

A performance simulation program for inter-turbine burner(ITB) turbofan engine was made with the variable specific heat components method,the influence of cycle parameters such as fan pressure ratio,compressor pressure ratio,bypass ratio,turbine inlet temperature on engine performance was analyzed comparatively.

Based on code analysis of particle simulation programs and loop optimization techniques,the computing code of a typical particle simulation program,3D macroscale pseudo-particle simulation program is optimized on by optimized compiling and code rebuilding in this paper.
