Flow control with artificial intelligence

Fluid control has been one of the great engineering challenges for decades. The Navier-Stokes equations, turbulence, and the interaction between multiple scales make modeling and mastering flow extraordinarily complex. In this context, platforms like HydroGym represent a qualitative leap by offering a standardized environment where artificial intelligence and, in particular, reinforcement learning can be applied to discover control strategies that were previously only possible with extremely costly ad hoc simulations. HydroGym provides more than 61 validated environments, from laminar to turbulent flows, with systematic variations of the Reynolds number reaching up to 400,000, including 2D and 3D configurations. Most notably, agents trained on this type of infrastructure manage to transfer knowledge to unseen cases, such as a 38% reduction in aerodynamic drag on a three-dimensional wing without the need for retraining. This demonstrates that AI for businesses can be applied to solve fundamental physical problems and not just classification or prediction tasks.

For a technology company like Q2BSTUDIO, specialized in custom applications and custom software, the HydroGym example illustrates how integrating AI agents with physical simulators can revolutionize entire sectors. In practice, developing flow control solutions for aeronautics, energy, or industrial processes requires robust and flexible simulation environments. HydroGym supports multiple backends —finite volumes, spectral elements, lattice Boltzmann, etc.— and allows gradient-based optimization. This versatility is similar to what we offer when we combine AWS and Azure cloud services with business intelligence tools such as Power BI, creating scalable platforms that handle large volumes of simulation and control data. HydroGym agents' zero-shot transfer capability reduces exploration costs by four orders of magnitude, savings that any engineering company would value when implementing intelligent control systems.

From a business perspective, the lesson from HydroGym is clear: standardization and shared infrastructure accelerate innovation. However, each industry has its particularities. That is why, at Q2BSTUDIO, we offer custom application development to integrate artificial intelligence algorithms into production processes, adapting the capabilities of platforms like HydroGym to specific needs, whether in fluid simulation, logistics, or manufacturing. Furthermore, cybersecurity is crucial when handling sensitive simulation data or connecting control systems to the cloud; our pentesting and cybersecurity services ensure that the infrastructure is protected. Finally, the analytics of these agents' results is enhanced with Power BI and business intelligence, transforming terabytes of flow data into operational decisions.

In short, HydroGym is not just an academic advancement, but a success case showing how the combination of artificial intelligence and robust simulation environments can generate transferable solutions. Companies that bet on AI for businesses with specialized platforms and technical support will be better positioned to solve the most complex challenges of fluid dynamics and beyond.
