Example Sentences:

	1.	The end show that coefficient of convective heat transfer at thermal boundary condition is higher than that at definite heat flux boundary condition . if according to dimensionless equation of heat convection , nu number of the latter almost is mutiplied 1 . 47 times of the formal , but the coefficient of convective heat transfer in tube between this two condition is almost equal 研究结果表明:在实验室中电加热方式得到的管外对流换热系数低于工程中传热条件下的管外对流换热系数,若按传热准则式关系,后者的努谢尔特数约为前者的1 . 4倍;而管内的对流换热系数在两种边界条件下的差别不大。
	2.	In this paper , the working fluid is air . experimental study of the nine different structure parameters of 3 - d ift with staggered arrangement fins in the reynolds number range of 250 to 30000 is performed to investigate the characteristics of heat transfer and flow friction behavior . analyses and reduces the experimental data by the least square method , obtains the nusselt and fanning friction fitting criterion equations 本文以空气为工质，在re 250 30000范围内对九根具有不同肋形结构尺寸的肋叉排三维内肋管的换热及流动特性进行了研究，并运用最小二乘法分析和处理实验数据，获得努谢尔特数，范宁摩擦系数与雷诺数，肋几何参数的准则方程式。
	3.	It is found that , the heat transfer coefficients in the area after at stagnation point is higher than that of common jetting although the heat transfer coefficients are smaller at stagnation point , and , comparing to common jetting , rotary jetting contributes to the even distribution of heat transfer coefficients near stagnation point 结果表明，尽管旋转射流的努谢尔特数在驻点附近低于普通射流的努谢尔特数，但在壁面射流区高于普通射流的努谢尔特数。与普通射流相比，旋转射流导致驻点附近区域的换热特性趋于均匀化。
