Study on Cavitation Effects in Elastic Cylinder Displacement and Bubble Morphology: Modeling, Reliability, and Behavioral Analysis

Year: 2025

Type: article

Abstract: The shape of a bubble changes near an elastic boundary, and this alteration also influences the boundary itself. This study investigates bubble shape and boundary displacement near an elastic cylindrical boundary through an electric spark bubble experiment. Three parameters—dimensionless distance, elastic cylinder tension, and dimensionless size—are discussed and analyzed in relation to bubble shape. For studying elastic cylinder boundary displacement, a displacement formula is proposed by establishing a motion model, and impulse is used for verification. Furthermore, the elastic cylinder tension employed in this study has negligible impact on boundary displacement. Understanding how bubble shape changes near an elastic boundary, along with the corresponding boundary displacement, provides valuable insights into the stability and durability of materials and structures under similar conditions. The elasticity of the cylinder and its displacement response to external forces can help predict long-term behavior, contributing to the reliability assessment of engineering systems involving elastic boundaries and fluid dynamics.
