This paper presents mainly a new HPC/CFD numerical simulation for airflow around the rigid sail for Lupo90 boat in Constanta harbor conditions. The first part of the work displays the performed numerical simulation in turbulent flow based on the 3D sail. The presented model has high capacity of towing and it can be installed onboard existing ships. This is the result of the HPC (high performance computing) and CFD (computational fluid dynamics) which is a mixture of actual hardware and software at high level computing power applied to Lupo90 boat. All data for rigid sail is analyzed in a turbulent flow in commercial fluid dynamics ANSYS module CFX available at Naval Academy and the work was supported by Romanian Ministry of Defense. Sail performance studying in turbulent flow for the rigid sail onboard ships was always a huge computational difficulty and the HPC/CFD analysis available can solve tricky tasks. The most common unconventional systems are hybrid propulsion systems are using fossil fuel and wind energy, this type of HPC/CFD method for propulsion investigation is now implemented by craft constructor CirusPlast SRL.
