Sub-Oceanic Volcanic Activity ANSYS Fluent Training

Description

The present project investigates the volcanic activity under the oceans. The eruptions occurring under the water surface can have various applications in oceanography and ocean engineering. Predicting the oceans’ behavior can be of great importance. Predicting the oceans’ behavior under such extreme conditions can provide huge data for meteorological, and weather forecasting sciences while preventing natural disasters such as tsunami.

This product is the third chapter of the VOF Multiphase Model Training Course.

The geometry is designed in ANSYS Design Modeler software. In addition, an unstructured mesh grid is generated using ANSYS Meshing software. As a result, 42,751 cells were generated.

Sub-Oceanic Volcanic Activity Methodology

In this project, the multiphase VOF model has been used to model an ocean under which multiple volcanos are erupting. Open channel flow along with Open channel wave boundary submodel is enabled to model the waves moving on the surface of water by enabling shallow/intermediate waves submodel.

One type of wave has been introduced into the domain using fifth order stokes wave theory.  Evaporation and condensation mass transfer using Lee model is also enabled to predict the volume of vapor generated to due immense temperatures that occur on the time of volcanic eruption and the hydrodynamic effects of such eruptions and vapor generation is investigated over the oceans’ wave pattern.

Conclusion

In this project, the interactions between the volcanic activity under the ocean’s surface with the passing waves over the water surface has been examined. It is shown that the dynamics of the vaporized water influence the hydrodynamic of existing waves and disrupt their pattern.
