- Abstract
- This paper deals with the effect of an adjacent viscous fluid on the torsional vibration of a Circular rod. The rod is in contact with the viscous fluid at one end face, and the other end face is torsionally excited by a transducer. The interaction between the torsional vibration of the rod and the fluid has been studied theoretically. Expressions for the natural frequencies and damping rate of the torsional vibration have been obtained through exact and approximate solutions.
