Above all , the surface of the gas turbine blade including stator and rotor heat transfer coeficience with no film cooling hole was studied with the main stream reynolds number of 150000 , 200000 50000 , 300000 , 350000 , 400000 . then , the heat transfer coefficience when all cooling holes opened and only one cooling hole opened was studied partly . and it ' s studied how the mainstream reynolds number , blowing ratio and the position of holes affect the heat transfer coefficience of the surface of blade 对导叶和动叶，都是先研究了在150000 ， 200000 ， 250000 ， 300000 ， 350000 ， 400000雷诺数下，没有气膜冷却时的表面换热系数分布，然后研究了气膜孔全打开和只打开单排孔时的表面换热系数分布曲线，重点研究来流雷诺数，吹风比和不同孔位出流对换热系数分布的影响规律。
In fact , the outlet flow of vane in the hydroelectric set is non - uniform flow for a variety of possible reasons . the flow is unsteady flow relative to vane and blade , and it is the main factor that affect self - excited vibration and dynamic characteristic of guide vane and hydraulic - turbine , which affect directly the power set to run safely and stably 非均匀来流相对于导叶、叶片必然是一种非定常流。这种非定常流造成导叶和转轮叶片的激振，是产生导叶和叶片动应力，改变它们频率的最主要因素，而导叶和叶片的动力特性直接影响水轮机的稳定性。
The main research outcomes were as follows : ( 1 ) the paper applied quasi - three dimensional design model and optimization design model based on si flow surface that was effected by runner ( impeller ) and guide vane jointly . the vortex flow , blade thickness limitation and runner ( impeller ) blade force functions were taken into account . the paper got the improved runners of hl240 type , which were runner hlx240d and runner hlx240e 主要成果有： ( 1 )应用考虑转轮来流有旋、叶片有限厚及转轮(叶轮)叶片力作用的转轮(叶轮)与导叶联合作用的基于s _ 1流面的准三维设计模型和优化设计模型，研究出了hl240的改进型转轮： hlx240d和hlx240e 。
Scramjet combustor may realize the subsonic - combustion mode and supersonic - combustion mode respectively based on the control of fuel in variable flight conditions . isolator has great effect on mode transition and preventing unstart of inlet . inlet can be unstarted by raising the back pressure result from chemical energy release in the combustor 计算研究表明，在相同的来流条件下，供油规律对燃烧室的工作模态有着重大的影响；在不同的来流条件下，可以通过调节供油规律使燃烧室分别实现亚燃模态和超燃模态；隔离段对防止燃烧引起的压力升高对进气道的干扰和燃烧室的模态转换具有重要的作用。
Numerical simulation and analysis of wind environment in an urban residential district are carried out , based on the theoretical research conclusions mentioned above . airflow fields distributions of pressure and turbulent quantities are obtained and laid out . statuses of wind environment with two different inflowing - azimuths are discussed 基于上述基础理论研究对住宅小区风环境(住宅小区热环境的主要组成部分)进行了数值模拟及分析，讨论了两种不同角度来流的风环境状况：气流组织、风压分布、湍流量分布等。
