中文摘要：
依据核心流传热强化原理,设计了一种新型粗杆-细杆组合式折流杆换热器,建立了相应的物理和数学模型,并对其传热与流动特性进行了计算模拟,并将计算结果和相同杆径的折流杆换热器进行了比较。结果表明,该新型换热器壳程的对流换热系数与折流杆换热器相当,但流动阻力远远小于折流杆换热器,综合性能优于折流杆换热器,而且Re数越高,优势越明显。
英文摘要：
On the basis of the concept of heat transfer enhancement in the core flow,a new type of shell-and-tube heat exchanger with a combination of different diameter rod was designed.Corresponding mathematical and physical model on the shell side about the new type heat exchanger were established,and the fluid flow and heat transfer characteristics were numerically investigated.Simulation results showed that the heat transfer coefficient of the new type of heat exchanger approximates that of rod baffle heat exchanger,but the flow pressure drop is much less than the latter,which indicated that the comprehensive performance of the former is superior to that of the latter,especially under high Reynolds numbers.
