柴油机掺水燃烧性能评估及决策仿真平台研究

Research on Assessment and Decision Making Simulation Platform for Performance of Diesel Engine Mixed with Water

针对柴油机掺水燃烧中不同掺水比例的性能评估及最优决策问题,基于灰色决策和灰色关联分析建立了柴油机最佳掺水比例决策及评估模型,为最佳掺水比例的选择提供了理论支持;并通过MATLAB语言和(图形用户界面)GUI开发实现了具有关联分析、最优决策等功能的柴油机掺水燃烧性能评估及决策仿真平台。通过仿真实例表明,仿真平台能够有效地实现柴油机最佳掺水比例决策以及性能评估,具有良好的可行性和有效性。

Focusing on assessment and decision making of the performance of diesel engine mixed with water under different water blending proportion, the grey decision making model for the best water blending proportion and evaluation model were established and implemented with the language of MATLAB based on grey decision making and grey-correlation analysis at first, which can offer theory supporting for the decision making of the best water blending proportion. The assessment and decision-making simulation platform was designed by GUI, which has the function of correlation analysis, decision making of the best water blending proportion, etc. The simulation platform case shows that, the platform can effectively realize decision-making for best water blending proportion and performance evaluation of diesel engine, and owns good feasibility and effectiveness.
