Abstract :
This research delves into the complex
dynamics of high-pressure, hot, and dynamic liquids
flowing through piping systems. To better understand
the various factors that affect the torsional vibration of
these liquids, the study uses a coupled nonlinear partial
differential equation to analyze generating variables
such as fluid flow heat flux, mass ratio, pipe thickness,
internal pressurization, vertical motion, longitudinal
direction kinetic energy of the inner fluid, and crosssectional area change. The ANSYS CFD R2022a
software is used to simulate the model, and a threedimensional model is used to investigate the dynamic
behavior of the thin pipe. The numerical modal analysis
is performed in the configuration of fluid-structure
interaction, and the study also examines the vibratory
behavior of the fluid-conveying pipe. The results indicate
that the velocity was 7.5% lower in the pipe with plaque
model than in the normal pipe model, while pressure and
WSS were 94.9% and 74.41% higher, respectively. The
study also conducts parametric studies on the effect of
temperature, pressure drop, and velocity change on the
frequencies. Additionally, the research suggests that a
gas column input signal exists in the pipe, which can
cause severe vibration when it comes into contact with
unreasonable vibration. This study highlights the
importance of determining the ideal design for pipes to
restore their usual functions and avoid excessive
vibration.”
