Conducting practical experiments to improvise the design can be time and resource-consuming, in many cases, it is impossible to perform.
CFD tools can accurately predict and analyze the performance of vessel/equipment with low cost and time.
The following are some of the marine and aerodynamic design optimization
Optimization of marine vessel hull design
Optimization of wind turbine
Evaluation of aerodynamic design for vehicles
The fishing trawler built by JJ Marines has 350hp engine and an average speed of 10knots but even after upgrading the engine to 450 hp the trawler couldn't reach the desired speed of 12knots...
