Abstract

In this research, fluid-structure interaction including transient flow in a viscoelastic  pipe has been studied in the frequency domain. The main purpose was to investigate the  water hammer problem using extended transfer matrix method in a typical reservoir-viscoelastic pipe-valve system. One of the generally expected advantages of frequency domain analysis is that the integral form of equations in the time domain would be transformed into algebraic form. Here it would be  more beneficial to utilize frequency domain methods since convolution integral which appears in viscoelastic models in time domain will also vanish. Transfer matrix method has been adopted to the transient flow in a viscoelastic pipe to derive field matrix where a non-oscillating valve is considered as a boundary condition. The generalized Kelvin-Voigt model was used to simulate the viscoelastic behavior of the pipe wall. The proposed model has been explored to solve two well-known case studies of fluid-structure interaction in the frequency domain. Results of both cases confirm the good agreement between analytical and experimental data. To investigate the simultaneous effects of viscoelasticity and fluid-structure interaction in the frequency domain a sample problem has been analyzed. Results for different conditions including interactional and non-interactional system together with both viscoelastic and elastic pipe material have been illustrated and compared. Also, a comparison among 3-element, 5-element, and higher order Kelvin-Voigt models has been performed based on which one may deduce the appropriateness of 3-element model.
