讨论了内置螺旋叶片转子换热管内不可压缩黏性流体的流动及传热问题,建立了描述其流动的数学模型,给出了换热管横截面上定常流动的解的存在唯一性。
The boundary problem of an incompressible viscous fluid in a plain tube inserted with helical blade rotors has been investigated.The corresponding mathematical model was established.The existence and uniqueness of the velocity for time-periodic flow were proved in the cross section of the rotor-inserted tube.
