This project aimed to develop an accurate CFD model for a full-scale pneumatic wave generator which would create waves of up to 2m in height for surfing. Developing such a design by taking into account all the constraints and limitations of the mechanical component is extremely challenging and requires conducting a detailed and careful parametric study. Another challenge associated with such full-scale projects is the computational cost of running domains with tens of million of cells in a transient mode. This project utilised our team’s exclusive High Performance Computing (HPC) facilities, which enabled running several simulations on hundreds of CPUs, resulting in a much shorter turnaround time, representing an essential aspect of this particular project. This successful design will be built in multiple locations in the world in the near future.
