For the present two les models , adopting the subgrid eddy viscosity concept and introducing the transport equation of turbulence energy k , the subgrid scale turbulence is parameterized by the turbulence energy k and the length scale of turbulence / ( k - 1 model ) . in addition , vegetation is considered as an internal source of resistant force and turbulence energy 在应用大涡模拟方法求解数值计算模型控制方程时,亚网格雷诺应力项沿用了亚网格涡粘性系数思路,引入亚网格紊流脉动动能k的输运方程,建立了关于亚网格紊流脉动动能k和紊流特征长度l的k - l模型求解。
This paper takes the independent power enterprise " huaan power corporation " as its analysis objective , and by introducing the concept of competitiveness and analyzing the internal source and external climate of the huaan power , the paper offers detailed analysis and discuss concerning the cultivation , elevation and administration of huaan power ' s competitiveness based on the theory of competitiveness . the paper also proposes the implementation plan , in order to offer a strategic reference for huaan power ' s sustainable development 本文以独立发电企业华安电力公司为分析对象,在简要介绍竞争力概念、来源的基础上,通过分析公司内部资源和外部环境,运用竞争力有关理论对华安电力公司竞争力的培育、提升与管理进行了详细的分析和探讨,并提出了相应的实施方案,以期为华安电力公司的可持续性发展提出战略性的参考。
