Print version Email story Tweet story
Hardware IBM has delivered the world's second fastest computer (and the world's fastest unclassified computer) to the National Energy Research Scientific Computing Center (NERSC). The machine, second only to IBM's own ASCI White computer, will be used for modeling internal combustion engines, global climate change, and developing new materials.

Application: CFD Analysis of a Commercial Plasma Reactor

Application CFD Canda and CFDRC, in conjunction with KyungWon Tech of Korea, have simulated [pdf file] two commercial high-density plasma reactors of the type used in integrated circuit wafer production. The study concentrated on flow and temperature distribution in the chemical vapor deposition (CVD) process.
In recent years considerable amount of research was devoted to plasma and electromagnetic modeling of process chambers, however thermal aspects were often omitted by assuming constant chamber temperatures. Variation in temperature distribution leads to variation in precursor and intermediate concentrations, which in turn changes surface adsorbtion and surface reaction rates.

News Fluent has released a major new version of their airflow modeling software Airpak.

Designed for HVAC, Health & Safety, and Environmental engineers, the latest version of Airpak has several enhancements including better CAD integration, a macro function for building simple models of diffusors, a detailed solar loading model, an animation capability, and several speed enhancements.

"The demand for airflow modeling to be done upfront in the design process for ventilation systems is heating up," says Airpak Product Manager Walter Schwarz, "and more and more firms are selecting Airpak as their tool of choice. The features that we've added with this new release are our response to the continuous market demands for faster model building, faster solutions, and easier ways to produce effective pictures, plots and animations from simulation results."

CFD and Sinking Tea Leaves - A Mystery Solved

Application Fluent previously used CFD in it's investigations into confounding bubble movement in beer, now AEA Technology has used CFD to determine why heavy tea particles collect at the center and not the perimeter of a cup of stirred water.

Both are fun and informative articles.

Application: Optimizing Waste Incinerators and Gas Scrubbers with CFD
Posted Wed June 13, 2001 @09:22AM
Print version Email story Tweet story
Application By utilizing extensive customizations in the STAR-CD user source routines, NOELL KRC-ENERGIE-UND-UMWELTTECHNIK, were able to simulate an entire waste incinerator and a single loop flue gas scrubber.

Waste incinerators have become an attractive alternative to landfill sites. By burning the waste, municipalities get the double benefit of waste volume reduction and generation of electrical power. NOELL used CFD to optimize flow patterns for mixing and cooling purposes.

To ensure reliable functioning and availability of the plant, it is essential to avoid hot regions near the wall that might damage the refractory material. It is also necessary to ensure good mixing and a complete as possible burn up, which is achieved by optimising the geometry, air supply configuration and operational conditions.
"Comparisons with measured data and observations in existing plants are very encouraging, confirming that STAR-CD is capable of providing realistic simulations and valuable insight into the operations of these incinerators."

Flue gas scrubbers are used to capture harmful substances from coal and waste fired power plants. Two phase Lagrangian tracking of spray droplets, with interphase heat and mass transfer, was utilized to model a parallel-flow single-loop HCl scrubber.

For accurate modelling, the absorption of harmful substances into the evaporating drops must also be handled, requiring inclusion of inter-phase heat and mass transfer in the simulation. A model describing the separation was implemented in STAR-CD via user subroutines, and a droplet-wall model was introduced to describe the behaviour of droplets splashing into wall films.
