Print version Email story Tweet story
CD-adapco The CD adapco Group invites you to a free workshop:

Predicting fuel cell behavior with CFD
October 11th, 10:00 am -- 3:00 pm
Bellevue Hilton
Bellevue, Washington

The keynote speaker will be Professor John Van Zee, of the University of South Carolina. Prof. Van Zee will discuss application of CFD coupled to electrochemistry modeling to PEM fuel cell design and analysis. By coupling electrochemistry models with the advanced CFD capability in CD adapco Group's solver STAR-CD, it is possible to get significant insight into issues such as heat transfer, fluid flow, membrane saturation and electrical current density.

Print version Email story Tweet story
ANSYS FLUENT Fluent Inc is pleased to announce two one-day seminars, held October 28 and 29, 2002 in our Evanston, IL office intended for those who are new to CFD and/or those who would like to learn more about the application of CFD in the process equipment design industries.

The main goals of these seminars are to make you more successful using CFD by having a more thorough knowledge of the underlying physics and numerical techniques in our software, as well as to teach engineers, scientists, and managers about the latest technical developments and how they can be used to model and improve process unit operations.

New Software: Fluent Delivers Indoor Environmental Airflow Modeling
Posted Wed September 04, 2002 @03:36PM
Print version Email story Tweet story
ANSYS FLUENT Fluent Inc. announces the availability of Airpak/RSF - a new service that significantly reduces the entry cost for using engineering simulation software in the design of buildings and other facilities. This new subscription-based service delivers Airpak airflow modeling software through a secure internet portal. The user pays for simulation time, rather than having to purchase additional hardware and software. This pay-as-you-go option lets building designers get started with powerful airflow modeling tools for less than $6,000 allowing costs to be scaled to project needs. Airpak helps building designers to better understand and visualize the performance of various ventilation systems. It quickly and accurately simulates room airflow patterns, temperature distribution, contaminant distribution, ventilation effectiveness, and thermal comfort so designers can optimize their ventilation systems design and minimize risk exposure well before construction begins.

"I saw the value of airflow modeling years ago, but couldn't manage the upfront costs of the better simulation packages. The Airpak/RSF lets me have the best of both worlds. Now, I can scale my airflow modeling usage and costs to fit my project workload, and get all the computing horsepower I need from any location, at any time. My clients appreciate being able to visualize how the design will perform, and I value the competitive advantage it gives me in the proposal process," says Paul Martin of Sigma Psi Consulting.

Application: Passenger Thermal Comfort Model Helps Optimize HVAC Systems

Application Lin-Jie Huang
Senior Staff Research Scientist
Delphi Harrison Thermal Systems
Lockport, New York

By developing a novel vehicle thermal comfort model, Delphi Harrison Thermal Systems has been able to evaluate the performance of many more heating / ventilation / air conditioning (HVAC) system designs than was ever possible in the past. By using this model a more thorough investigation of the design parameters space brings the final design closer to optimum. Traditionally, HVAC design alternatives have been evaluated by testing prototypes in wind tunnels, a very time-consuming and expensive process. Though automotive OEMs and suppliers have developed many cabin climate prediction models over the last several years, Delphi’s new virtual thermal comfort engineering model goes considerably farther than it’s predecessors by integrating a 16-zone human physiology model that predicts human comfort by calculating skin temperatures. The model uses computational fluid dynamics (CFD) to predict local thermal comfort as a function of air temperature, surrounding surface temperatures, air velocity, humidity, direct solar flux, as well as the level of activity and clothing type of each individual. This technology is currently being used to design and optimize HVAC systems and in the future its use is to be extended for the development of control algorithms and the calibration of electronic controls.

CFD Review by Nick Wyman

On August 1st I visited CFX Engineering Software in Waterloo, Ontario Canada and was given previews of several upcoming software packages from this tier-1 CFD vendor.

The Waterloo office is home to CFX's software development teams for CFX-TASCflow, CFX-TurboGrid, CFX-Post and the largest portion of the CFX-5 team, in addition to a portion of the sales and support group for North America. There are approximately 60 employees in the office, half of whom are involved in software development.

My visit was hosted by Dr. Jeff Van Doormaal, product development manager for CFX-TurboGrid, CFX's grid generation software tool for turbomachinery applications.

Note: For your chance to ask CFX Engineering Software about CFD development, add your question to this discussion.
