News It's not on their web site yet, but Flow Science has elected two new vice presidents.
[John] Ditter joined Flow Science in 1992. He will be responsible for software engineering, hardware needs and customer support & training. Prior to joining the company, he worked at McDonnell Douglas Space Systems Company. He graduated from the Milwaukee School of Engineering with a B.S. in Mechanical Engineering and earned a master's degree in theoretical and applied mechanics from the University of Illinois in 1986.
[Robin] Berry joined Flow Science as financial manager in January 2001. Prior to joining the company, she worked with the public accounting firm of Betts, Bishop & Loggains and worked as financial manager at Sol y Sombra. She will be responsible for Flow Science’s accounting, financial planning, budgeting, tax planning, and human resources matters.
With Dr. C.W. Hirt, Chief Technologist and founder of the company, Ditter and Berry form the core of the company’s planning and development efforts. All report to the president of the company, Mr. Thomas S. Jensen.

Stereo Display Without Glasses

Hardware Yes you read right - no bulky eyewear! StereoGraphics (makers of the popular CrystalEyes 3D stereo visualization technology) has introduced an autostereoscopic display.

The system uses a digital flat panel display to yield true depth perception provided by Stereo3D technology. The system works by separating the left and right eye frames for display on even and odd pixels. By lighting the pixels at an angle from behind, the correct frame is viewed by each eye delivering the same effect as the bulky glasses.

By several accounts this technology works well and gives the user a realistic 3D experience. By removing the requirement for eyewear, the new system allows several people to share the experience at once. Until I get mine, I'll have to rely on 3D "perspective" viewing.

Application: CFD for Chemical Mixing
Posted Wed July 25, 2001 @10:23AM
Print version Email story Tweet story
Application Chemical Online has posted a couple of articles which relate the use of CFD in the chemical process industry. Specifically, CFD is applied to optimize mixing in a batch reactor (a large tank used for mixing chemicals - much like a kitchen blender).

The first article uses CFD to match tank, impeller, and baffle geometry as well as additive feed location. The simulations were performed to determine the mixing time which is critical to mixing efficiency. The case is particularly interesting due to the use of three different impeller models. One, a simple velocity data method, does not explicitly model the impeller, but enforces known velocity and turbulence values (taken from experiment) in the impeller region. The other methods model the impeller explicitly, but differ in their treatment of the frame of reference change. One uses the true transient sliding-mesh interface and the other employs averaging at the interface. In addition, the accuracy of k-e and RSM turbulence models for this geometry was examined. Accuracy is quoted to be within experimental error.
