Markus Anders, Stefan Holst, Jim Ippolito, Malcolm McGilp – CD-adapco Regulatory efficiency requirements for electric machines and the tremendous price rise in material costs of permanent magnets are two important motivators for analyzing the thermal performance of electric machines in greater detail. For a detailed, more accurate thermal simulation, a complete 3D-CAD model needs to be built and multiphase flow calculations are performed. A process where CD-adapco can now offer a more streamlined simulation approach is by combining SPEED and STAR-CCM+. Dynamics 33 - Read more...
In this report, the performance of the Standard Cirrus glider is simulated using STAR-CCM+. To calculate the important transitional boundary layer ow, the γ-Reθ transition model is used. The study is performed to test the quality of the transition model and to create a validated reference model of the glider’s performance in steady level flight. The validated model will in future studies be used to improve the performance and handling quality of the glider and serve as a reference model for other simulation tools. Dynamics 33 - Read more...
Fred Mendonça & Deborah Eppel, CD-adapco One of the greatest challenges facing the aerospace industry is improving the aeroacoustic noise generation of their products to meet today’s more and more stringent noise pollution standards. As flow-induced noise makes a significant contribution to the overall output decibels, it seems essential to understand how to optimize the aircraft design in order to minimize the flow-induced noise without impairing the general performance of the air-vehicle.

Prashanth Shankara, CD-adapco This article details results from the numerical simulations on the NASA Trapezoidal Wing geometry, focusing on the high lift prediction using the CD-adapco solver STAR-CCM+. Computations and validation were based on the guidelines and experimental data provided for the 1st AIAA High Lift Prediction Workshop (HiLiftPW-1) to assess the numerical prediction capability of STAR-CCM+ for high lift configurations.

Justin Smothers, JSC Engineers Jon Thornham & Chris Thornham, FLO Cycling Prashanth S. Shankara, CD-adapco In the grand theater that is modern competitive sports, the equipment is as crucial as the competitor. The advent of cutting-edge engineering technologies has pushed the boundaries of competition far and beyond what one could have envisioned a decade ago. In this multi-billion dollar industry, to stay ahead of the competition, high-end engineering plays a critical role in improving equipment constantly. Dynamics 33 - Read more...
Geneviève Dutil, Lx R&D inc. & Titus Sgro, CD-adapco As anyone who has ever ridden a bicycle on a windy day will testify, aerodynamics play a big part in cycling. Perhaps more than any other sport, competitive cycling is dominated by aerodynamics, as cyclists, clad in aerodynamic clothing and helmets, are forced to adopt uncomfortable crouched position on their bikes, minimizing their frontal area and reducing their exposure to the oncoming air.

Stephen Ferguson, CD-adapco The Lotus T128 is set to revolutionize the LMP2 category of the World Endurance Championship. Borrowing heavily from a process perfected in Formula 1, the T128 will be the first LMP2 car to be designed using an intensive engineering simulation process. I spoke with Stéphane Chosse, who is in charge of the design and engineering office at ADESS AG, to find out exactly how CFD has influenced the aerodynamic design of this exciting new racecar.
