    Abstract

    The ultrasonic Doppler velocimetry (UVP) method is well known for the laminar flow stream in a circular tube. In many practical situations, deformed tubes or, non-parallel streamlines are involved. An improved experimental arrangement of the UVP transducer is needed to define the real velocity-vectors of the flow when the streamlines are not parallel to its wall. An experimental approach has been used with two sets of transducers in perpendicular to each other to obtain the magnitude of the real velocity vector (vreal), the direction of velocity-vector, and axial velocity component along the flow direction. The experiments were carried out using a proposed arrangement of UVP transducer for flow visualisation in a squeezed elastic tube. The results show that the 2D velocity profiling found to be more accurate using the present transducer arrangement, which is important for generating further information such as shear rate, flow rate, etc.
