Simulation and experimental estimation of the free wavenumbers for helically grooved tubes
Simulation and experimental estimation of the free wavenumbers for helically grooved tubes
The dynamic characterisation of tubular elastic structures is relevant
to many fields in the industry. They are a vital component for many processes
involving fluid flow, heating, or cooling, etc., where grooves are frequently
introduced to alter flow, and thus enhance heat transfer. Thin-walled tubes with
helical features have been previously studied numerically and analytically, but
experimental validation is still lacking or limited. In this paper, the wave
propagation characteristics of a cylindrical tube with helicoidal grooves are
investigated experimentally. The Wave Finite Element method is applied to a 3D
model of this structure and a correlation method is used on a real tube to
experimentally estimate and validate these results. In comparison to a tube without
grooves, both numerical and experimental methods show that the helicoidal
grooves cause two distinctive but closely valued bending wave branches to appear
in the dispersion curves. Being a finite structure, the effect of the grooves is also
visible in the mode shapes of the tubes which will also be presented, where
bending modes become unrestricted to lying in a single preferential direction.

Abstract
The dynamic characterisation of tubular elastic structures is relevant
to many fields in the industry. They are a vital component for many processes
involving fluid flow, heating, or cooling, etc., where grooves are frequently
introduced to alter flow, and thus enhance heat transfer. Thin-walled tubes with
helical features have been previously studied numerically and analytically, but
experimental validation is still lacking or limited. In this paper, the wave
propagation characteristics of a cylindrical tube with helicoidal grooves are
investigated experimentally. The Wave Finite Element method is applied to a 3D
model of this structure and a correlation method is used on a real tube to
experimentally estimate and validate these results. In comparison to a tube without
grooves, both numerical and experimental methods show that the helicoidal
grooves cause two distinctive but closely valued bending wave branches to appear
in the dispersion curves. Being a finite structure, the effect of the grooves is also
visible in the mode shapes of the tubes which will also be presented, where
bending modes become unrestricted to lying in a single preferential direction.
