The nonsteady flow of fluids through expansible tubes

A digital computer solution of the equations of fluid motion predicts the pressures in an expansible tube through which liquid is flowing. To obtain a stable solution, it is necessary to assume that the rate of change of area with time is proportional to the rate of change of velocity with time. Thi...

Description
Summary:A digital computer solution of the equations of fluid motion predicts the pressures in an expansible tube through which liquid is flowing. To obtain a stable solution, it is necessary to assume that the rate of change of area with time is proportional to the rate of change of velocity with time. This assumption is shown to be a reasonable one. Calculations for the rate of travel of pressure pulses are in good agreement with experimental results.
