Environments

FluidGym provides 35+ environments across four fluid physics domains, each available in easy, medium, and hard difficulty levels.

Flow Past Cylinder

Active flow control around a cylinder via jet or rotational actuation. The goal is to suppress vortex shedding and reduce drag.

Easy (Re = 100)

Medium (Re = 250)

Hard (Re = 500)
Cylinder Easy Cylinder Medium Cylinder Hard

See Flow Past Cylinder for the full environment list and API reference.

Flow Past Airfoil

Flow past a NACA 0012 airfoil with the goal of improving aerodynamic efficiency by maximizing the lift-to-drag ratio.

Easy (Re = 1×10³)

Medium (Re = 3×10³)

Hard (Re = 5×10³)
Airfoil Easy Airfoil Medium Airfoil Hard

See Flow Past Airfoil for the full environment list and API reference.

Rayleigh-Bénard Convection (RBC)

Thermal convection driven by buoyancy between a heated bottom plate and a cooled top plate. Heaters along the bottom wall are controlled to enhance heat transfer.

Easy (Ra = 8×10⁴)

Medium (Ra = 4×10⁵)

Hard (Ra = 8×10⁵)
RBC Easy RBC Medium RBC Hard

See Rayleigh-Bénard Convection (RBC) for the full environment list and API reference.

Turbulent Channel Flow (TCF)

3D wall-bounded turbulent channel flow with blowing/suction actuation on the bottom or both walls to reduce skin-friction drag.

Easy (Re = 180)

Medium (Re = 330)

Hard (Re = 550)
TCF Easy TCF Medium TCF Hard

See Turbulent Channel Flow (TCF) for the full environment list and API reference.
