振荡管流换热的理论解

THEORETICAL SOLUTION ON HEAT TRANSFER IN OSCILLATORY PIPE FLOW

  • 摘要: 本文从流体在管内振荡的运动方程和流体及管壁的能量方程出发,经过变量转换对常微分方程组进行求解,得到了计及管壁影响的振荡流体轴向换热的一般理论解。由这解,可以导出各种特殊条件下的表达式,包括已有的各种解析解。本解经数字化而制成各种图线,它们与已有的实验数据基本吻合。

     

    Abstract: Starting from the equations of motion of the oscillatory pipe flow, together with the energy equations of the fluid and of the pipe wall, by solving the set of ordinary differentia equations using variable transformation and taking pipe wall effect into account, a general analytical solution of the axial heat transfer of oscillatory flow is obtained. Based upon this analytical solution, formulae for heat transfer in various special cases can be derived, some of which reduce to known analytical results. The...
