The Future of CFD Engineering and Its Potential for Advancements

CFD engineering, an acronym for Computational Fluid Dynamics engineering, has come a long way since its birth in the 1940s. It involves solving problems that involve fluid flows through numerical methods and computer simulations. Given its extensive applications in various fields ranging from aerospace to automotive to energy, it is apparent that this area of engineering possesses substantial potential for advancements.

Integration with Artificial Intelligence and Machine Learning

The integration of artificial intelligence (AI) and machine learning (ML) promises to revolutionize CFD engineering by improving the accuracy and speed of simulations while reducing human error. A particular application of AI in CFD engineering is the use of reinforcement learning techniques to develop optimized control policies for dynamical systems such as aircraft or engines under different operating conditions.

Additionally, ML algorithms trained on vast amounts of simulation data can help identify complex nonlinear relationships between variables that can be challenging to detect analytically. By automating many tedious and time-consuming tasks involved in setting up and running numerical simulations, AI and ML will free up engineers’ time to focus more on discovering new solutions rather than just analyzing results.

“Machine learning’s ability to capture non-intuitive correlations between different physical phenomena may result in discoveries about existing manufacturing processes or materials science not possible using classical physics-based modeling techniques,” says Alexander Titus, CEO at LiquidPiston Inc., a Connecticut-based engineering company specializing in engine design optimization and research.

Increased Use in Medical and Biological Applications

The healthcare sector is gradually embracing CFD engineering technology as researchers look for ways to perform better fundamental research into biological fluids—blood flow, airflows in lungs—and understand pathophysiology. Research involving medical devices, implants, prosthetics or drug delivery systems, requires an understanding of fluid dynamics to ensure efficacy and safety.

Moreover, CFD technology has been utilized in the design of prosthetics that can improve patient independence. “We’re able to run simulations using data from a particular patient’s imaging scans to create negative casts of what their limb is actually shaped like,” says Dan Reznik MD, clinical co-director of the UCLA Biomechanics Research Laboratory. “We use those casts to build custom-designed sockets for their artificial limbs to accommodate any irregularities in the shape or volume of the tissue.”

Advancements in High-Performance Computing and Cloud-Based Simulations

The advances in high-performance computing (HPC) infrastructure and cloud computing have enabled the processing and storage capacity required for large-scale numerical simulations. HPC clusters equipped with GPUs accelerate calculations hundreds of times faster than traditional CPU servers. Companies such as Amazon Web Service (AWS), Microsoft Azure, IBM, Google, and Alibaba are investing more heavily into cloud-based computational resources allowing users to harness these powerful systems, even on personal devices.

“CFD simulations require intensive computations and heavy memory usage that only possible with supercomputers,” says Dr. Jie Hu, senior research scientist at the National Renewable Energy Laboratory (NREL). “Accessing cloud-based parallel computation would significantly streamline projects, making it comparatively easy and affordable for smaller organizations to adopt these technologies when necessary.”

HPC not only makes simulations faster but also allows scientists to solve increasingly complex problems by dividing them into smaller pieces called domains and solving each one simultaneously. It further negates the need to solve all sections continuously rather single snapshots where small shadows portray thousands, hence making predictiveness more exact and extensive.

We see that CFD engineering integrates numerous disciplines, involving physical, chemical, biological, mathematical principles, which are perhaps the most important domain of engineering. Its future looks bright, with expanded applications and integration with other cutting-edge technologies that promise to enhance the accuracy, speed and scope of CFD simulations.
