Analysis of Coriolis Effect in a Curved Pipe Conveying Hydrogen Using Timoshenko Beam Element
Coriolis flow meters are widely used in hydrogen flow measurements. The low molecular weight and low density makes it difficult for conventional techniques to measure hydrogen flow. Many researchers have worked on the FE analysis of Coriolis mass flow meter. Here, a three-node Timoshenko beam element is formulated to model the curved pipe conveying hydrogen in three-dimensional configuration. Paidoussis and Issid (J Sound Vibr 29(3):267–294, 1974) derived the equations of motion for the combined structure and fluid domain including added mass effect, Coriolis effect, centrifugal effect, and the effect of pressure on the walls of the pipe. These equations are converted to the FE formulation using Galerkin technique and are validated.
