Computational Fluid Dynamics (CFD)
Powerful Computer Modeling & Design
Airglide conducts the CFD design for our Airglide™ ALS systems in-house with our resident staff experts. The Airglide principals have been longstanding and recognized experts, with leading-edge computational fluid dynamics (CFD) analysis software and hardware tools.
Our designs routinely include CFD analysis for both global hull flow regime and localized air nozzle injection patterns. This level of detail insures that every design is optimized for your specific ship geometry and operating conditions.
Computational Fluid Dynamics
The basic steps of the CFD analysis for ALS includes:
Capture hull geometry and create CFD mesh
Determine global hull flow characteristics and flow regime
Model discontinuities, appendages and propulsive flow regimes
Locate ALS air injection points and injection criteria
Model ship resistance with ALS off and ALS on
Visualize and calculate lift and drag forces
Measure pressure distributions for required air volume and pressure
Establish static parameters for optimization analysis
Run optimization analysis iterating to maximum efficiency and fuel reduction
Create coordinates for design of ALS system
