Standard self-propulsion simulations are performed for a fixed speed while controlling the RMP's of the propeller(s) to achieve the force balance.
Fully automated framework makes these simulations more accessible by reducing the required man-hours from our side. Check out our price list.
What do we need from you for self-propulsion simulations?
- CAD file
- Mass properties of the ship
- Open water curves (thrust and torque)
What can we calculate for you?
- Achieved RPM, thrust, torque and power
- Sinkage and trim
Self-propulsion simulations are performed using the actuator disk model that only requires open water thrust and torque curves as an input: KT(J) and KQ(J).
Thanks to the Lloyd’s Workshop on Ship Scale Computer Hydrodynamic Simulation and Uljanik Shipyard, we compared the achieved speed of a general cargo carrier and a car carrier directly to sea trial measurements, with errors smaller than 1%.
But that’s not all, we performed grid sensitivity studies for both ships, showing consistent results with grid refinement. For all the details, take a look at this paper.
