โœฆ Synopsis


The characteristic equation for the growth rate of a disturbance on a viscoelastic jet is derived by paralleling the classical development for the Newtonian liquid. For the particular viscoelastic model examined. the theory predicts the viscoelastic jet to be less stable than a Newtonian jet, under identical dynamic conditions.

A finite viscoelastic shaft whose model is based on the spring and dash-pot (Keluin element) is asymptotically stable as long as its angular speed is less than or equal to the square root of the least eigenvalue of the system. We construct numerically the least eigenvalue by using an iteration metho
