Mathematical modelling of Love waves propagation in viscoelastic waveguide loaded with complex fluids

Love waves propagation in a viscoelastic waveguide loaded on its surface with fluids of finite thickness is investigated this paper. The Maxwell and Kelvin-Voigt constitutive equations are employed order to describe the fluid viscoelasticity. By solving motion different media (viscoelastic fluid, elastic substrate) imposing suitable boundary conditions, an accurate simple generalized complex dispersion equation established for waves. Subsequently, comparison made published literature some particular cases, very good agreement showed. A detailed study was conducted by varying key parameters such as operating frequency, thickness. subjected various glycerol concentrations, wide range dynamic viscosity, representing both Newtonian behaviors. Theoretical analysis shows that reasonably predict characteristics responses waves, more appropriate low concentration and, high at frequency. Results also evaluated influence layer curves. obtained results can be useful design optimization wave sensors.
