1、 Principles and Characteristics
1. The working principle is that when a particle with a mass of m moves at a velocity of υ in a pipeline rotating at an angular velocity of ω on the p-axis, the particle experiences acceleration and force from two components.
a、 Normal acceleration, also known as centripetal acceleration α r, has a magnitude equal to ω 2r and is oriented towards the P axis;
b、 The tangential acceleration α t, also known as Coriolis acceleration, has a magnitude of 2 Ωυ and is perpendicular to α r. Due to composite motion, Coriolis Fc=2 Ωυ m acts on the particle in the α t direction, and the pipeline exerts a reverse force - Fc=-2 Ωυ m on the particle.
When a fluid with a density of ρ flows at a constant velocity υ in a rotating pipeline, any section of the pipeline with a length Δ x will experience a tangential Coriolis force of Δ Fc.
