Examples
- Experimental investigation on convective heat transfer and flowing friction in risg tubes
内螺旋外棘齿管对流换热与流阻实验研究 - The experimental results of air heat transfer show that the relative fin height , relative fin width , relative fin pitch and density of 3 - d ift with staggered arrangement fins all have an effect on heat transfer and flow friction . especially , the effect of fin density is bigger
空气换热实验的结果表明：肋叉排三维内肋管的相对肋高、相对肋宽、相对肋间距以及肋密度均对其对流换热特性有影响，其中肋密度的影响较大。 - Turning the grinding machine round , driven the barrel body to rotate by the transmission , the work piece that makes in the barrel , grinding stones and adding and grinding pharmaceutical and water in right amount , mix in barrel , is it is it flow layer to produce through action of gravity to make use of , flow friction on layer grind cutting , reach the work piece and process the surface quality taken
?转研磨机，是由传动带动桶身旋转，使桶内的工件、研磨石与添加适量研磨剂和水，在桶内混合，藉由重力作用而产生流动层，进而流动层的磨擦进行研磨切削，达到工件加工所要的表面品质。 - 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
