Dynamic behavior of the cavitation bubbles collapsing between a rigid wall and an elastic wall

چکیده
There are various bubble cavitation phenomena in daily production and life, near-wall is the most common one. This paper studies dynamics between a rigid wall an elastic wall, by changing distance two walls initial position of bubble, several different collapse patterns obtained. Then, we discuss changes migration distance, gravity, maximum radius during cavitation. Finally, numerical simulation used to successfully acquire satellite bubbles appearing process which good agreement with experimental results. We obtained pressure from explained formation bubble.

Fission of Collapsing Cavitation Bubbles
High-speed observations (for example, Lauterborn and Bolle 1975, Tomita and Shima 1990, Frost and Sturtevant 1986) clearly show that though a collapsing cavitation bubble approaches its minimum size as a coherent single volume, it usually reappears in the first rebounding frame as a cloud of much smaller bubbles or as a highly distorted single volume (see, for example, figure 2). This paper exp...
متن کاملDynamic Behavior of an Oil Droplet Adhered to the Wall Surface in a Channel Flow by the Lattice Boltzmann Method
The Lattice Boltzmann Method is used to simulate the dynamics of droplet deformation in a channel flow under various conditions. The droplet behavior has been investigated under transient conditions. For cases where the droplet remains attached to the surface, the shape deformation of the droplet during crawling is captured. It has been shown that there is a limiting value for the droplet volum...

15 صفحه اولDynamic Interaction between a Rigid Body and an Elastic Ring
Dynamic interaction between two bodies, where one is significantly more flexible than the other, is common (e.g. rotor-casing contact). This paper presents a linear model for simulating contact between rigid and flexible bodies. The motion between contacts is predicted by modal superposition, using separate models for the two components. During contact, the models are coupled via a linear conta...
