Beneath the Surface

Signs of a ship's passage can persist long after it's gone. The churn of its propellers and the oil leaked from its engines leave a mark on the water's surface that, in some cases, is visible even from orbit. (Image credit: A. Calado and E. Balaras) Read the full article

A class of curves

During my thesis, researching ways of flow around rocks and ships near the surface of water, I found a set of equations that can be used to model these weirder shapes. One example was the lemon curve, which you saw as the cricket ball simulation I showed earlier. The other is a generalised version of these that allows one to customise the location of bumps on the surface of the solid. The following plots were made in python.

Lemon curves (name courtesy of my fabulous sister @mrunmione) - the shape used to model a cricket ball

Crocodile curves (because they literally look like crocodiles)

Why are they important? ↓

It is important that when you model obstacles, you do so with at least second-differentiable functions, which means that they can be differentiated at least twice without behaving badly.

This is due to the nature of equations used to model fluids, called the Navier Stokes equations, which is based on Newton's 2nd law of motion, the force applied on an object is proportional to the acceleration (which is where the 2nd derivative comes into play).

Unveiling the Power of Computational Fluid Dynamics: Enhancing Engineering Solutions

In the realm of engineering and scientific simulations, Computational Fluid Dynamics (CFD) stands as a pivotal tool revolutionizing the way we understand fluid flows and their intricate behaviors. With its unparalleled precision and versatility, CFD has transcended mere mathematical calculations to become a cornerstone in optimizing designs, predicting performances, and propelling innovation across various industries.

The Essence of Computational Fluid Dynamics

At its core, Computational Fluid Dynamics revolves around the numerical analysis of fluid flow phenomena. This includes studying the interaction of liquids or gases within a defined space, unraveling complex patterns that would be otherwise unattainable through traditional experimental methods. By utilizing computer algorithms and mathematical equations, CFD enables engineers to simulate and comprehend fluid behaviors under diverse conditions, contributing to the creation of more efficient and effective systems.

Applications Across Industries

Aerospace Advancements

Boldly pushing the boundaries of aviation, CFD plays a pivotal role in aircraft design and performance enhancement. By comprehending airflows over wings, tail sections, and fuselages, engineers can refine aerodynamic profiles, thus reducing drag, improving fuel efficiency, and even minimizing noise emissions. This technology has paved the way for the development of sleeker, more fuel-efficient airplanes that are environmentally conscious and economically viable.

Automotive Innovation

In the automotive realm, CFD has redefined vehicle design paradigms. From optimizing the cooling systems to enhance engine performance to analyzing airflow around vehicles for improved aerodynamics, CFD aids in crafting automobiles that are not only aesthetically pleasing but also fuel-efficient and high-performing. The result? Cars that seamlessly marry form and function, delivering exceptional driving experiences.

Architectural Ingenuity

Even in the realm of architecture, CFD's impact is palpable. Designing structures that can withstand complex wind patterns, ensuring optimal ventilation within buildings, and predicting indoor air quality are all facilitated by CFD simulations. As a result, architects can construct buildings that are both aesthetically striking and environmentally sustainable, providing spaces that harmonize with the natural world.

The Future Beckons

As technology continues to advance, so too does the prowess of Computational Fluid Dynamics. With the increasing capabilities of supercomputers and more refined algorithms, the simulations are becoming faster, more accurate, and consequently, more accessible. This opens doors for smaller enterprises to harness the power of CFD Software, democratizing innovation across industries.

In conclusion, Computational Fluid Dynamics is not merely a tool; it's a transformative force driving progress in diverse sectors. Its ability to unravel the intricacies of fluid behaviors, optimize designs, and predict outcomes is reshaping the landscape of engineering and beyond. From aviation to architecture, the ripples of CFD's influence are evident, promising a future where innovation knows no bounds.

So, as we stand on the precipice of endless possibilities, let us acknowledge the role of Computational Fluid Dynamics in shaping our world – a world where fluid dynamics are no longer just a mystery, but a realm of exploration and innovation.

Chemical processes are all about separation and mixing using unit operations. Chemical processes have always been a major user of computational fluid dynamics more so than ever. In this context, the oil and gas industry are the largest consumer of CFD services. Novel reactor technologies, advanced separation systems, innovative mixing techniques, complex internals such as baffles, static mixers, blades, impellers, sieve trays and distributors, multiphase systems (gas-solid-liquid), reaction driven flows, flow through porous media, flows with diffusion and advection, complex non-Newtonian flows, fluidization bubble dynamics are some of the processes where Paanduv is an excellent choice.

Factor's New O2 VAM - The Evolution of Light and Aero

With the Tour hitting the mountains, Factor officially releases the next O2 VAM, the brand’s climbing bike. It’s not just an instance of a few minor tweaks and slapping a new paint job on it though, Factor worked with their sponsored teams to find out where they could help their riders gain time, and went to work. The result is a new 02 VAM that is not only lighter, but also faster, stiffer, and…

Reapproaching Supersonic Air Travel

Before the Concorde even began regular flights, protests over its sound levels caused the U.S. and many other countries to ban overland commercial supersonic flight. Those restrictions have stood for fifty years. (Image credit: NASA; via Physics Today) Read the full article

Aorta: structure to rupture

Regular readers have probably already realised that I have very broad interests in engineering from aircraft and power stations [see ‘Conversations about engineering over dinner and haircut‘ on February 16th, 2022] to nanoparticles interacting with cells [see ‘Fancy a pint of science‘ on April 27th, 2022]. So, it will come as no surprise to hear that I gave a welcome address to a workshop on…

New understanding of how particle shape controls grain flow could help engineers manage coastal erosion

As a river cuts through a landscape, it can operate like a conveyer belt, moving truckloads of sediment over time. Knowing how quickly or slowly this sediment flows can help engineers plan for the downstream impact of restoring a river or removing a dam. But the models currently used to estimate sediment flow can be off by a wide margin.

An MIT team has come up with a better formula to calculate how much sediment a fluid can push across a granular bed—a process known as bed load transport. The key to the new formula comes down to the shape of the sediment grains.

It may seem intuitive: A smooth, round stone should skip across a river bed faster than an angular pebble. But flowing water also pushes harder on the angular pebble, which could erase the round stone's advantage. Which effect wins? Existing sediment transport models surprisingly don't offer an answer, mainly because the problem of measuring grain shape is too unwieldy: How do you quantify a pebble's contours?
