Future Work

The findings of this thesis could lead to several further investigations which would increase the understanding of the flow regime around surface piercing masts and decrease the plume structure generated by a submarine mast.

As shown in Chapter 5, streamlined bodies and double mast configurations can offer a significant advantage over conventional cylinders. Thus, the numerical investigation can be extended to cover streamlined body masts and mast fairings, to further reduce the plume structure and understand the limitations of using streamlined bodies instead of bluff bodies. However, additional experimental data would be required to validate the non-cylindrical mast sections. The loads calculated in this project during the experimental and numerical analysis can be used to develop experimental set-ups to validate the double mast

configurations, thus increasing the certainty of the numerical predictions.

Furthermore, the knowledge obtained through the CFD predations can be applied to other high Froude number situations, such as vertical rudder struts or foils, to optimise and increase performance of vessels with surface piercing configurations, such as hydrofoilers.

In addition to studying different mast configurations, analysis on the transition point of laminar to turbulent flow on bluff bodies at the respective Froude numbers has the potential to improve the accuracy of the plume structure and bow wave height.

Finally, an investigation into the performance of different numerical models could decrease the simulation time or increase the accuracy of the results. In particular, the URANS models discussed in Chapter 3 to determine the reasons for the limitations in capturing the full plume structure could be examined more accurately.
