CFD in Marine | CAEbridge Simulation Approach


CAEbridge performs accurate and fast turn-around CFDi simulations of sea vessels to address the following design concerns:

  • Fuel efficiency
  • Endurance
  • Passenger comfort & security
  • Payload handling

In essence, our simulations aid designers with the optimization of hull shapes, better design of propulsion and steering systems, and detailed sea keeping analysis.
 
In contrast with towing tank experiments and empirical methods, CFDi provides significant insight into the flow physics helping to obtain optimal results in fewer design iterations. In the past decade, the industry has relied on PANEL methods which are severely limited in their ability to model realistic sea conditions. With significant advancements on geometry handling, flow modeling and computational resources, there is significant shift towards more accurate and complete CFDi models.
 
In the above regard, CAEbridge utilizes the Complete Modeling approach coupling of the following modules:

  • Unsteady RANSi (Reynolds Averaged Navier Stokes) Flow Solver
  • VOFi (Volume of Fluidi) Method for keeping track of the two fluid media, i.e. air and water
  • 6-DOFi (Degrees of Freedom) Motion Solver for modeling the motion of the vessel
  • Mesh Deformation Solver for accommodating the motion of the vessel

In contrast with PANEL methods, we are able to model viscous effects and turbulence, atmospheric wind profiles and sea-wind-vessel interactions as a complete system with no compromise on the geometric representation quality.
With access to customized solvers, CAEbridge's efforts include:

  • Numerical model validation & enhancements
  • Design analysis & optimization

On the validation side, we are assessing our solvers' ability to represent accurate wake patterns and force profiles around known ship hull shapes. In addition, we are enhancing our dynamic floatation models that incorporate mooring line forces alongside their fluid force counterparts for offshore platform applications.
 
On the design analysis and improvement end, we are developing innovative analysis and optimization approaches on the simulation results of realistic yacht geometries and water sports equipment.
 
Since CAEbridge has a special interest in marine applications, we are eager to hear from you about your design goals, processes and bottlenecks, so that we can provide you with the most effective solutions possible.
