ATZ - A Digital Approach to the Aeroacoustic Evaluation of HVAC Blowers

OEMs are increasingly focusing on the acoustic efficiency of components and subsystems in search for an overall reduction of the main noise contributors in passenger cars. This is particularly true with rotating machinery. Exa Corporation and Mahle Luxembourg investigated the prediction of an automotive HVAC module blower using a three-dimensional compressible and unsteady  Computational Fluid Dynamics (CFD) solver based on the Lattice-Boltzmann Method.

Electric & Hybrid Vehicle Technology International - Shape of Things to Come

There is a century of design evolution behind the shape of modern cars- vehicles that have been built around the packaging of the powertrain and the need for a passenger cabin that seats X number of adults in comfort, while providing a driver with an acceptable field of vision. Aerodynamics has always been a part of the former requirement, providing cooling to the powertrain and latterly brining performance benefits (in most cases drag reduction and thereby improved fuel economy), evolving the aesthetic and function layout into the form seen today.

Upstream Technology - Uncracking the Code

New 3D multi-phase flow simulation technology makes it possible to predict the flow of both oil and water through rocks using only rotary sidewall cores

Doing less with more is a mantra in low-price environments. Reducing reservoir uncertainty is simultaneously a driving need when devising production plans, so its vital to know as much as possible about how much oil is in the ground and how fluids will move through the reservoir rocks.

JPT - Need a Faster Measure of Relative Permeability? Take a CT Scan and Follow with Digital Rock Analysis

BP is working to push digital rock testing into the mainstream of conventional development.

The latest step in its decade-long journey was a deal with Exa, a software firm that partnered with BP to develop a program modeling two-phase flow in conventional reservoirs based on data from virtual 3D images of small samples of reservoir rock.

Compared with methods used by traditional core labs, this approach significantly reduces the time and cost required, and offers the processing software in a form that could help broaden the use of this disruptive technology.

Exa, BP Sign Multi-Year Commercial Agreement for Exa DigitalROCK

As a result of three years of cooperative research and validation, Exa is now bringing to market the first predictive computational solver for relative permeability, a goal that has long been elusive for the oil and gas industry.  This new capability will help engineering teams make more informed decisions on wells, production facilities and resource progression, including enhanced oil recovery.

OTC 2017 - BP attains ‘holy grail’ of digital rock technology through new Exa agreement

BP's proprietary digital rocks technology program is getting a key upgrade from an agreement with Exa Corp., which will enhance BP’s ability to predict the flow of oil and water in digital images of reservoir rock.

The multi-year commercial agreement is for Exa’s DigitalROCK relative permeability software solution based on the company’s multi-phase fluid flow simulation technology.

SAE - Exa simulation aims to keep ADAS sensors clean

Looking "backwards" will soon become increasingly necessary for aerodynamics’ engineers and simulation specialists. In this case, it's about the industry's interest in abandoning exterior rearview mirrors in favor of small cameras, partly to reduce the vehicle's coefficient of drag (Cd) for improved fuel efficiency and also to enhance safety systems to provide a wide-angle view around and behind a vehicle.

Automotive World - It's time for OEMs to clean up with digital simulation

Advanced simulation tools can help enhance several characteristics of vehicle design, from aerodynamics to the way that dirt sticks to cameras 

There aren’t many car owners who enjoy seeing their vehicle covered in muck – it annoys them from both an aesthetic and a practical point of view. Filthy doors don’t look great, and dirty handles aren’t much fun to touch….subscription required

Engineering.com - PowerFLOW 5.4 Brings Dust, Dirt and Water into Aerodynamics Simulations

Product design engineers need to evaluate how their designs are affected by environmental factors, and simulations are a time- and resource-efficient way to perform these evaluations.  Exa’s PowerFLOW Computational Fluid Dynamics (CFD) simulator is one popular simulation tool, and the recent release of PowerFLOW 5.4 expands its capabilities and better models real-world factors such as dust, dirt, and water. This release improves four primary feature sets:

ATZ Off-Highway - Total Noise Solution for a Directional Drill

Off-highway machine and equipment manufacturers are working to lower their product’s noise level. Total radiated noise includes contributions from different sources including cooling fan, engine, transmission, muffler and the hydraulic system. In the following, the results of a methodology  developed by Exa and Vermeer using a simulation tool to  predict and optimise total noise for a horizontal directional  drill are presented.

Endurance-Info.com - La FIA travaille d’arrache-pied pour éviter le décollage des LM P1

Si on vous dit qu’une LM P1 peut décoller en cas de sortie de piste, on ne vous apprendra rien. La hantise des différents acteurs de l’Endurance reste le décollage d’une auto. Les ailerons de requin sont apparus il y a quelques années afin d’éviter l’envol des prototypes en perdition. La FIA ne cesse de travailler pour parer à tout souci à haute vitesse. A ce titre, elle collabore avec des spécialistes de la simulation informatique qui planchent sur des solutions qui permettront de prévenir davantage les décollages des LM P1 et autres catégories prototypes.

Truck & Off-Highway Engineering - Engineering with Simulation and Data

Companies are discovering new simulation techniques, especially optimization; the next step is to combine simulation with sensor data and predictive analytics to create even more robust off-highway equipment.

Making off-highway equipment, such as construction or agriculture machines, more efficient continues to be a priority after the final phase-in of the U.S.  EPA Tier 4 Final emmisions regulations.

FIA - Launch Experts

The FIA is working with computer simulation specialists to find solutions that will further prevent car launches in LMP1 and other high-speed categories.

A sudden spin can be disastrous in motor sport. A good result can be lost and reputations ruined in the blink of an eye. But in the case of LMP1 cars, a high-speed spin can make the risk of a violent airborne crash a distinct possibility.  page 30
