Effect of Shear on Ultrasonic Flow Measurement Using Nonaxisymmetric Wave Modes

Effect of Shear on Ultrasonic Flow Measurement Using Nonaxisymmetric Wave Modes

Nonaxisymmetric wave propagation in an inviscid fluid with a pipeline shear flow is investigated. Mathematical equation is deduced from the conservations of mass and momentum, leading to a second-order differential equation in terms of the acoustic pressure. Meanwhile a general boundary condition is...
