表面换热系数 meaning in Chinese
surface coefficient of heat tra fer
surface(film)thermal conductance
surfacethermal conductance surface coefficient of heat transfer
Examples
- The results denote that the sand layer can greatly enhance heat transfer in high temperature region because it changes film boiling to liquid film evaporation in the sand layer
在高温金属面上覆盖砂层后，可将高温面上的膜沸腾转化为砂粒表面的液膜蒸发，从而大幅度提高表面换热系数，强化冷却能力。 - The heat transfer enhancement is different under different oscillator . there is the optimum oscillation intensity under which the heat transfer coefficient will be increased by about 30 percent . the change of outlet structure size of a resonance chamber shows little effect on the strength of heat transfer : the pressure of the optional heat transfer coefficient always is between 0 . 4mpa and 0 . 6mpa , and the optional heat transfer coefficient is enhanced by 30 percent or so
不同的振荡强度，强化换热的效果也不同，存在一个最佳强度，此时的强化换热效果最好，可以将表面换热系数提高30 %左右；对于同一共振腔，配合以不同的出口结构尺寸，对于换热效果的强化的影响变化不大：出现最佳强化效果时的压力基本都在0 . 4 - 0 . 6 ，最佳的强化效果也都是将表面换热系数提高30 %左右。 - 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。
