The impacts of both the velocity head and momentum distribution in the t - junction of a tailrace surge tank on the critical stable sectional area of the tank were analyzed by using gardel ' s empirical equations for t - junction flow . based on thoma ' s theory , a formula of the critical stable sectional area is derived . 5 基于gardel关于三通管水头损失的经验公式,研究分析了连接管处的速度水头以及进出调压室水体与尾水隧洞水体之间的动量交换,对有连接管的尾水调压室稳定断面积的影响,并在托马( thoma )假定基础上,推导出相应的调压室稳定断面的计算公式; 5
The fifth chapter sum up the article and view the work . the simulation results indicate : ( 1 ) exchanging of sea - air and force of dynamical and thermodynamic processes is very important to bring and maintain sea surface wind . shf is mostly energy sources and lhf is negative effect in some area 模拟结果充分表明: ( 1 )感热和潜热的海气交换和动量交换(摩擦作用)对于海面风的发展和维持起着重要作用,潜热加热是海面风中最主要的能源,感热通量在一武汉理工大学硕士学位论文定区域对海面风风场有负面影响。
