The Collapse of a Cloud of Bubbles
نویسنده
چکیده
A numerical simulation of the collapse of a cloud of bubbles has been used t o demonstrate the development of an inwardly propagating shock wave which grows rapidly in magnitude. The fully non-linear nonbarotropic homogeneous flow equations are coupled with single bubble dynamics aud solved by a stable numerical scheme. The computational results demonstrate khe structure of the shock wave as well as its strengthening effect due t o the coupling of the single bubble dynamics with the global dynamics of the flow through the pressure and velocity fields. This appears to confirm the speculation of Morch and his co-workers that such shock formation is an important part of cloud collapse.

Numerical Computation of Shock Waves in a Spherical Cloud of Cavitation Bubbles
The nonlinear dynamics of a spherical cloud of cavitation bubbles have been simulated numerically in order to learn more about the physical phenomena occurring in cloud cavitation. A finite cloud of nuclei is subject to a decrease in the ambient pressure which causes the cloud to cavitate. A subsequent pressure recovery then causes the cloud to collapse. This is typical of the transient behavio...
متن کاملShock waves and noise in the collapse of a cloud of cavitation bubbles
Calculations of the collapse dynamics of a cloud of cavitation bubbles confirm the speculakions of M#rch and his co-workers and demonstrate that collapse occurs as a result of the inward propagation of a shock wave which grows rapidly in magnitude. Results are presented showing the evolving dynamics of the cloud and the resulting far-field acoustic noise.
متن کاملSome Current Advances in Cavitation Research
Several recent experimental and allalytical investigations of cavitating flows have revealed new phenomena which clearly affect how we should view cavitation growth arid collapse and the strategies used t o ameliorate its adverse effects. On the scale of individual bubbles it is now clear that the dynamics and acoustics of single bubbles are severely affected by the distortion of the bubble by ...
متن کاملInvited Lecture Cloud Cavitation: The Good, The Bad and the Bubbly
In many cavitating liquid flows, when the number and concentration of the bubbles exceeds some critical level, the flow becomes unsteady and large clouds of cavitating bubbles are periodically formed and then collapse when convected into regions of higher pressure. This phenomenon is known as cloud cavitation and when it occurs it is almost always associated with a substantial increase in the c...
