knudsen number meaning in English
克努森数
克努曾数
Examples
- Electric knudsen number
电气克努森数 - Magnetic knudsen number
磁克努曾数 - 4 . the paper proved that when the cooling channel belongs to the transitional region from macro - scale to micro - scale , whether the macro - scale theory or the micro - scale theory will be used depends on the accuracy that the researcher reqired , and does not need to depend on the knudsen number
4 、当冷却通道属于宏观尺度到微观尺度的过渡区域时,求解计算是采用宏观理论还是采用微观尺度的理论,主要是看研究者对求解答案的精度要求,而不必一定按照kn数进行判断。 - The hot - dip - depth and temperature difference between fluid and platelet wall are influenced by many factors , such as the coefficient of heat conductivity of platelet and fluid , the coolant fluid , the knudsen number , and so on . high temperature make kn number become bigger , and then microscale effects become notable
3 、热浸深度、流体与层板壁面的温差大小要受层板的导热系数、冷却剂流量及流动的kn数等因素的影响。高温条件使kn数增大,微尺度效应增强;而高压条件下kn数减小,微尺度效应减弱。 - Through comparison and analysis the result gained from micro - scale theory and macro - scale theory , we can drew several conclusions as follows : 1 . as the knudsen number ( kn number ) is very small , the inaccuracy would be neglect , when the macro - scale theory is used to solve the problems which were proposed in the paper
通过对微尺度理论和宏观尺度理论研究结果的比较,可得以下几条结论: 1 、由于knudsen数( kn数)很小,用常规尺度理论求解本文所研究的微小通道内的流动阻力,其误差可忽略不计。
