摘要： Methods and systems for detecting a plume of a first fluid in a second fluid using an acoustic wave are provided, where the first fluid has a different acoustic index of refraction than the second fluid. A horizontal array having a plurality of receiving elements receives an acoustic signal propagated through the second fluid and at least one refracted signal refracted by the first fluid. The acoustic signal and the at least one refracted signal form a received signal. An interference pattern is detected from the received signal over the plurality of receiving elements. The interference pattern is due to interference between the acoustic signal and the at least one refracted signal. A horizontal angle of refraction is determined between the acoustic signal and the at least one refracted signal from the interference pattern. The horizontal angle of refraction is indicative of a physical characteristic of the first fluid.

摘要： Simulators and methods for simulating an acoustic field of an acoustic waveguide are provided. A sound speed profile of the acoustic waveguide is generated, where the acoustic waveguide has a region of a first fluid within a second fluid, and the first fluid has a different acoustic index of refraction than the second fluid. The sound speed profile and predetermined parameters of a sound source and a receiver are applied to a parabolic equation (PE) model of sound propagation in the acoustic waveguide. The acoustic field of the acoustic waveguide is determined from the PE model. The acoustic field includes an interference pattern from interference between an acoustic signal of the acoustic source and at least one signal refracted by the region of the second fluid.
