Overview
abstract
The Krauklis wave is a slow dispersive wave mode that propagates in a fluid layer bounded by elastic media. There are indications that Krauklis wave plays a significant role in a variety of wave propagation phenomena in seismology, acoustics, engineering and hearing physiology. This is defined by its large amplitudes, high dispersion and confinement to the fractures filled with fluid. In the prospecting seismology Krauklis wave might be an important component of the hydro-fracturing, seismic wave propagation in fractured reservoirs, and fracture detection. The obtained asymptote solutions revealed good coincidence with the exact solutions. The found analytical conditions accurately evaluate the transitions between different asymptote. Resonance conditions for the Krauklis wave predict existence of resonances within the seismic frequency range at a laboratory scale. If verified, this will allow experimental studies of the Krauklis waves in a variety of realistic models that simulate fractures filled with fluids.
