News Desktop Engineering Online has an article detailing the rise of CFD, historically associated only with analysts, in the design environment.
How do you design a racing yacht to take advantage of every puff of wind, even when another boat blocks the air current? How do you see inside an experimental fuel cell while it’s operating? How do you design ventilation fans to enable firefighter access and passenger exit in case of fire in a subway station? CFD. That’s how.

Researchers Use CFD to Examine Artificial Heart Valves
Posted Wed June 11, 2003 @08:06AM
Print version Email story Tweet story
News Numerical modeling techniques, developed at the Georgia Institute of Technology to simulate the flow of water around hydraulic structures such as bridge foundations, are being used to better understand the complex patterns of blood flow through artificial mechanical heart valves.

The research could yield the most accurate description to date of the turbulent flow environment blood cells and platelets are exposed to as they pass through an implanted mechanical heart valve — information that researchers hope will lead to improvements in current mechanical valve testing and design procedures, and help reduce the potential for thromboembolic complications.

Backed by a four-year, $1.4 million grant from the National Institutes of Health, the research is being spearheaded by Ajit Yoganathan, Regents’ professor in the Wallace H. Coulter School of Biomedical Engineering at Georgia Tech and Emory University and an internationally renowned expert on artificial heart valves and cardiovascular fluid mechanics research; and Fotis Sotiropoulos, an associate professor in the School of Civil and Environmental Engineering and a leading expert in computational fluid mechanics.

News 16th AIAA Computational Fluid Dynamics Conference
Hilton Walt Disney World
Orlando, Florida
23 - 26 Jun 2003

The 16th AIAA Computational Fluid Dynamics Conference is being held in conjunction with the 33rd AIAA Fluid Dynamics Conference to enable close synergism and interaction between CFD and a broader range of fluid dynamics research. This year marks the 30th anniversary of the conference, and a special session commemorating the event has been organized. The program consists of 28 invited and contributed sessions. Emphasis is on advances in CFD methods for steady and time resolved flow, shape optimization, and LES.

AIAA Offers Distance Learning CFD Courses
Posted Tue June 10, 2003 @09:26AM
Print version Email story Tweet story
News The AIAA is offering a series of CFD courses as part of their Distance Learning Professional Development service.

The comprehensive, three-part series of courses will prepare you for a career in the rapidly expanding field of computational fluid dynamics and fluid turbulence. Completion of these three courses will give you the equivalent of one semester of undergraduate and two semesters of graduate work. The courses are supported extensively with textbooks, computer programs, and user manuals. You can use the computer programs to develop your own code, or you may modify the existing code for assigned applications. You will need access to a computer with a PC pentium processor, FORTRAN compiler, and graphics package for the software applications. A fundamental knowledge of computer programming and familiarity with a basic graphic package are required.

  • Introduction to Computational Fluid Dynamics
  • Advanced Computational Fluid Dynamics
  • Computational Fluid Turbulence

    The courses are designed for engineers, scientists, and technical managers who are interested in learning the fundamentals and principles of CFD.

    New Software: Gridgen Version 15 Released
    Posted Thu June 05, 2003 @09:59AM
    Print version Email story Tweet story
    Grid Generation Pointwise, Inc. began shipping Gridgen Version 15, the latest release of its meshing and pre-processing software for computational fluid dynamics (CFD), today to customers worldwide.

    One major suite of new features is focused on minimizing the user's interaction with large and complex meshes. Specific tools include a CAD-style layer manager, pick masks, and grid groups. "As CFD has matured, so has the sophistication of our customers", said John Chawner, Pointwise's president. "They are applying CFD to ever larger and more complex geometries, and the tools in V15 will ensure that geometric complexity doesn't spill over to the meshing process itself."

    A second suite of new features includes enhancements to Gridgen's hybrid meshing capabilities, specifically the extrusion of near-wall prism layers. Re-extrusion is a new tool for continuing the extrusion process for a mesh, including complete recall of all attributes and the ability to back-up the extrusion as well as continuing forward.
