CFD Used to Explore Truck Platooning Technologies
Posted Sun November 10, 2019 @09:56PM
Print version Email story Tweet story
Application Pointwise has published the case study, Researchers use CFD to Help Quantify the Benefits of Truck Platooning Technologies, which is based on research done at Auburn University.

The practice of drafting – where moving objects are grouped tightly together to conserve energy by exploiting the lead object’s slipstream – has been used in motorsports, cycling, and speedskating for years. Right now, however, drafting is too dangerous on the open road.

Print version Email story Tweet story
Application The sensitivity of bacteria to physical, chemical and environmental disturbances presents a challenge to maintaining microbial nitrification in wastewater treatment plants.

Researchers at the University of New Mexico conducted a series of experiments to understand the effects of surface roughness on annular nitrifying biofilm reactors (Roveto et al., 2019). Their team used FLOW-3D to find possible explanations for their experimental observations.

Print version Email story Tweet story
Application Wild Well Control has developed a new approach to shallow-water well capping involving heavy pre-planning using CFD analysis of the well plume.

A partial list of complications for capping shallow-water well events includes large radius surface boils, and large clouds of dangerous or explosive gas/lower explosive limit (LEL) capable of igniting and creating potential fire hazards at or near the well site.

HONDA Testifies a Major Breakthrough in Meshing Speed with NUMECA’s AutoSeal and HEXPRESS™/Hybrid
Posted Mon July 29, 2019 @05:13PM
Print version Email story Tweet story
Application I'm sure you have heard it before, "80% of the time spent on CFD simulation for aerodynamics is used just for preparing the set-up of the case". Typical challenges in the simulation preparation process are still: poor quality of the available CAD, resulting in dirty geometries containing holes and cavities, complex geometries, resulting in a large amount of manual input to create a quality mesh, and difficulty to quickly create design alternatives for iterative testing.

Several Leaps Forward for CFD Simulations of Hydrofoils
Posted Mon July 22, 2019 @11:02AM
Print version Email story Tweet story
Application While discussing with Xavier Guisnel from VPLP during the last marine session of the NUMECA User Meeting, the idea of revising the hydrofoil simulation standards appeared to be a necessity. He mentioned that "the desired lift force should be an input and not just an output of the simulation".
