Ultrasonic Tomography of Nonmixing Fluid Flows
Résumé
An ultrasonic method for simultaneous measurement of two-dimensional distributions of compositions and flow velocities in a system of two nonmixing fluids is proposed and implemented. The method is based on tomographic reconstruction of images of scalar and vector objects using a rectangular system of stationary transceivers. Images of simple objects (a vortex in a homogeneous fluid and a standing gravitational-capillary wave in a system of two nonmixing fluids) are obtained by this method.
