Computational Fluid Dynamics

Computational Fluid Dynamics (CFD) is a powerful tool for modelling complex flow physics relevant to air, surface and underwater platforms and weapon systems. This modelling can be performed for conceptual studies of new systems or for engineering analysis of system modifications.

There are many applications of CFD to maritime platform systems, including::

  • Impact of hull/appendage design changes on resistance and manoeuvring coefficients
  • Optimisation of propulsor/hull interaction for improved efficiency and reduced signatures
  • Detailed hydrodynamic assessment of propulsor design
  • Performance and manoeuvring of ultra high-speed underwater projectiles
  • Thermal plume dispersion and assessment of impact on flight operations
  • Superstructure aerodynamics and impact on flight operations
  • Minimisation of risk of exhaust re-ingestion into air intakes
  • Suppression of infrared signature
  • Dispersion of toxic gases in compartments
  • Compartment cooling and ventilation

CFD is becoming increasingly important in air vehicle and weapons aerodynamic analysis; to complement, or to an extent replace, conventional wind tunnel testing. Applications include:

  • Aerodynamic optimisation of configurations
  • Estimation of aerodynamic loads
  • Obtaining force and moment coefficients for flight modelling
  • Stores separation analysis

AVT engineers have significant experience in CFD modelling applicable to air and maritime systems, and can add significant value to your project through:

  • More optimal designs
  • Reduced reliance on costly experimental testing
  • Reduced design risk
  • Shorter product development cycles
  • Root cause analysis of in-service problems
