本文应用一元定常气体动力学理论,讨论了缓变截面圆管中绝热摩擦流动问题。在摩擦系数ξ为常数时,得到了问题的积分解。并引出了b(λ)或b(m)函数。给出了计算缓变截面圆管中绝热流动的能量损失的基本公式。
In this paper, the uniaxial steady gas dynamics theory is used to discuss the problem of adiabatic frictional flow in a slowly varying cross-section tube. When the coefficient of friction ξ is constant, the integral solution of the problem is obtained. And leads to the b (λ) or b (m) function. The basic formula for calculating the energy loss of adiabatic flow in circular tube with slowly varying section is given.
