โฆ Synopsis
A tube of circular cross section whose radius is a function of a slow variable Z = (1/R)z, where z is the co-ordinate in the axial direction and R is a large streamwise Reynolds number, may be designated a slender tube. An elementary approximation to the flow in such,tubes is obtained and results compared with an approximation based on the profiles obtained by Daniels and Eagles [7] for exponential slender tubes.

The effect of applying external pressure fluctuations on slender flux tubes is studied as a nonlinear initial value problem. Large amplitude velocity oscillations are seen to be produced when the frequency of the imposed fluctuations matches the natural frequency of the tube. Radiative cooling does
