We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Is it possible to model Cavitation-Ignition Bubble Combustion in Fluent or ANSYS CFD tools?

      All the machinery to do this is in Fluent, but this simulation is not practical on an industrial scale. The bubble collapse ( implosion part of the cavitation lifetime) will lead to an abrupt reduction of the bubble volume. The gas inside dissipates explosively into the surrounding liquid, along with a large heat release and pressure increase. This will lead to the propagation of an acoustic wave and generation of light. The latter part of this process is not manageable from a CFD perspective. The study of a individual bubble could perhaps be done as with an extremely fine mesh, but this is not an industrially practical solution.
