The Krauklis waves are slow guided waves generated in fluid-filled fractures and are characterized by their dispersive and resonating nature. We have developed an unconventional experimental apparatus to study the effects of fluid viscosity and fracture geometry as two import factors on the velocity of Krauklis waves. Our apparatus is based on the dynamic photo elasticity technique that is used to visualize the stress field generated by the propagation of the Krauklis waves. We consider two fluids with different viscosities and two fracture geometries of flat and saw-teeth. Based on our results, with the increase of the fluid viscosity, the velocity of the Krauklis wave decreases. In addition, we note that the fracture geometry strongly affects the characteristics of the Krauklis waves.
