New Software: Airpak 2.1 Released
Posted Fri December 20, 2002 @04:00PM
Print version Email story Tweet story
ANSYS FLUENT Fluent Inc. has released the newest version of its Airpak software. Airpak 2.1 is an easy-to-use airflow modeling design tool that allows for the accurate modeling of airflow, heat transfer, contaminant transport, and thermal comfort in ventilation systems, as well as external building flows. Airpak can also reduce risk for new designs and improve the efficiency of current designs while saving time and money.

"Airflow modeling is becoming an essential tool in building design," says Airpak Product Manager Dr. Walter Schwarz, "and our customers who have selected Airpak as their airflow modeling tool-of-choice have gained a competitive advantage over their competitors in design as well as enhanced their communication with customers concerning ventilation design performance."

Application: CFD Provides Value to Solutia

Application by Dave Davidson,
Nylon Technology, Solutia Inc, USA

(Dave Davidson passed away in late October. He was an asset to the CFD community and a great friend who will be sorely missed by all who knew him.)

Early in 1995, Monsanto implemented a CFD Initiative leading to a concerted application of the technology throughout the company. By standardizing on CFX-4, we simplified the learning process and made it trivial to share models across the organization. Since then, the CFD group has been closely monitored, checking cost against economic benefits for each case. Consequently, we have a large dataset of industrial CFD applications from which we can extract performance statistics on the benefits of CFD.

Economic impact

Because of the manner in which CFD adds value, it is impossible to precisely quantify this. However, we can estimate a lower bound to be the cumulative net income derived from all projects where CFD made the difference between success and failure; a conservative estimate is $35 million. In fact, one project’s return is in excess of $10 million of cumulative net income. Total cumulative investment in CFD is about $6 million, including salaries; therefore a conservative estimate of the payback ratio is in excess of 580%. This estimate excludes any contributions from technical service work. One such project, involving CFD and structural analysis at a customer site, helped prevent loss of a key customer who provided $40 million of annual revenue. The customer was convinced that we were to blame for low yields, and was threatening to bring in a competitor. The project results showed them that their equipment was at fault, they cancelled the competitor trial and we retained the entire sales volume. Subsequently we were able to use the results to suggest process modifications aimed at improving yield.

Since 1995, we have maintained approximately 1 full-time CFD practitioner per billion dollars of annual sales and the same ratio of CFD practitioners to enterprise employees (0.035%). Both the annual net income of about $4 million per user and the rate of return are continuing to increase.

Help for MFR Pump Simulation
Posted Tue December 17, 2002 @09:28AM
Print version Email story Tweet story
Help Desk I am simulating a small centrifugal pump(a inlet and an outlet)using mutiple rotating reference frame. The model of my pump (only fluid zones and wall) consists of two parts, one is the rotating part which is set to a rotating reference frame, the other is stationary part. The result is the stationary part are ok, but the rotating part only has absolute velocity (its direction is similar to the direction of rotation, maybe wrong), and I cannot find the relative velocity along the flow paths, which is very important for me.

Expecting your help!Thanks a lots!

Print version Email story Tweet story
ANSYS CFX The first Indian CFX Conference was held between the 2nd and 5th of December at the Hotel Le Meridian, Bangalore.

Two advanced two-day workshops were held on the 2nd and 3rd. The Advanced Turbomachinery Workshop attracted about 34 people from industry and academia. The Advanced Process Workshop attracted about 40 people form industry and academia. The participants were given a comprehensive overview of CFX software technology, exposed to a wide range of applications being done using CFX around the globe and received best usage practices, error estimation and such other practical tips. The tutors included Prof. Soundaranayagam, Dr. R. Dhinagaran, Dr. Georg Scheuerer, and Andre Braune for the turbomachinery course. Dr. Phil Stopford tutored the Process Workshop. The entire team enjoyed an evening of fun filled and competitive bowling at Megabowl, the site for the course dinner on the 2nd of December.
