摘要
通过对我国空调行业常用的4种整体式翅片管热器系统的试验研究,得出了工业应用Re范围内(Re<5000)换热和阻力的综合关联式。并对翅片表面性能作了综合性评价,为优化设计提供了科学依据。
The virtual contact loading method is developed to simulate the elasto - plastic contact phenomenon be - tween the screw flanks of a screwed - pipe joint . In the conditions of elasto - plastic small deforrnationt, the load and stress concentntion factor distributions along the threads and the stress distributions in the mating screw flanks are studied and the reasonal results are found out .
