1.
Investigations were carried out, under uniform wall temperature and constant heat flux boundary conditions,on heat transfer and frictional characteristics of transverse tube with large roughness for laminar and turbulent flow of oil in a condensation test facility.
在凝结换热实验台上 ,采用恒壁温法和恒热流法对油品在大粗糙度横肋管中的层流与湍流摩擦阻力与传热特性进行了实验研究 。
4)  low fin tube
低肋管
1.
For petal-shaped fin tube oil-cooler with helical baffle s, as the oil pressure drop in shell side is 90 kPa , the overall heat transfer coefficient of oil_cooler is 3200 W/(m2·K), which is 15% higher than that of low fin tube oil-cooler with helical baffles, and is 5 times as large as that of smooth tube oil-cooler with segmental baffles, so it is an efficient oil-cooler.
对于螺旋隔板花瓣管润滑油冷却器, 当壳程油侧压降为90 kPa时, 其总传热系数可达3200 W/(m2·K), 比螺旋隔板低肋管油冷却器高15%以上, 为普通弓形隔板光滑管油冷却器的5倍左右, 因而它是目前国内外传热效能最高的水冷壳管式油冷却器。
5)  orthogonal traverse rib tube
直角横肋管
6)  cross-fin(ned) tube
横向肋片管
