![]() DETERMINATION OF THE CRITICAL VELOCITY OF A FLUID FLOWING IN A PIPELINE RESTING ON VISCOELASTIC FOUNDATION
Dimitar Lolov In this paper is investigated the stability of a pipeline resting on viscoelastic foundation. The viscoelastic foundation is represented through the generalized Kelvin-Voigt model. Numerical investigations for a particular pipeline are carried out. Conclusions are drawn on the influence of the parameters of viscoelastic model on critical fluid velocity.
