CFD Analysis of Propulsion Systems and Cavitation for Marine and Shipbuilding Industry
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Achieving an optimal propulsion system early in the design phase ensures the vessel meets contract requirements while improving sea-going capacity and reducing vessel fuel consumption. Our solutions create a propeller digital twin early in the design phase, giving understanding of propulsion effects at full scale. From propeller in isolation to sub-systems to full system performance, design an optimal, innovative propulsion system that meets contractual and regulatory obligations at a lower cost.
Use our Propulsion Systems and Cavitation solutions to:
- Predict propeller performance, including the effects of cavitation and erosion.
- Optimize propeller designs for required operational efficiency.
- Simulate self-propulsion and analyze design-critical operating conditions.
- Improve existing fleet efficiency via energy saving devices and other refit options.
- Minimize vibro-acoustics, ensuring reduced environmental footprint and structural integrity.
- Provide accurate inputs to load calculations and system simulations.
Enteknograte offers a Virtual Engineering approach with CFD and FEA tools such as Ansys Fluent, StarCCM+ for flows simulation and FEA based Codes such as ABAQUS, Ansys, Nastran and LS-Dyna, encompassing the accurate prediction of in-service loads, the performance evaluation, and the integrity assessment including the influence of manufacturing the components.
CFD Analysis of Cavitation for Marine and Shipbuilding
For water pumps, marine propellers, and other equipment involving hydrofoils, cavitation can cause problems such as vibration, increased hydrodynamic drag, pressure pulsation, noise, and erosion on solid surfaces. Most of these problems are related to the transient behavior of cavitation structures. To better understand these phenomena, unsteady 3D simulations Modeling Cavitation of cavitating flow around single hydrofoils are often performed and the results are compared to experiments.
