Best Solver for Fuel Rod Bundle Subchannel Analysis?
Posted Thu February 17, 2005 @09:04PM
Print version Email story Tweet story
Help Desk Arnie writes "I have a problem regarding subchannel analysis in rod bundles, can anybody suggest a proper solver for subchannel analysis or suggest me any FVM scheme to solve it?

I would like to have the complete mass, momentum and energy equations with proper connectivity between adjacent subchannels. If there is any commercial CFD software available (my problem involves phase change), please let me know."

New Software: Fluent’s Introduces Icechip™ Software for IC Thermal Design
Posted Wed February 16, 2005 @09:31AM
Print version Email story Tweet story
ANSYS FLUENT Fluent Inc., the world leader in computational fluid dynamics (CFD) software solutions, announces the release of Icechip™, a new package-level thermal validation software for IC package designers.

Icechip is an addition to the portfolio of design simulation and verification tools from the Icepak division of Fluent Inc. These include Icepak, the system-level thermal design tool; Iceboard, the PCB-level thermal verification software; and Icemax, the parasitics extraction tool for IC packages. Icechip is designed to increase the fidelity of package thermal design by modeling details of IC package structures and it significantly reduces the turnaround time for simulations of today’s increasingly complex IC packages. The tool is developed in collaboration with Harvard Thermal, the industry expert in the use of ECAD-based interfaces to thermal simulation software.

Reaction in a Bubble Column (Ozonizer)
Posted Sat February 12, 2005 @10:38PM
Print version Email story Tweet story
Help Desk Ozone writes "Hello,

I want to study ozonization reactions and also the hydrodynamics using FLUENT. For the time being, we want to start with a simple phenomenon: Ozone-rich air will be bubbled into the water, and in the gas phase, the ozone will decompose to oxygen. Due to the increase in the number of moles, the volume of the bubbles will increase i.e. the bubble hold-up will go on increasing. We want to study how this effects the hydrodynamics.

Can you please suggest:

  1. Which reaction model I should choose? Volumetric reactions or particle surface reactions?
  2. This should be a multiphase model; but when I choose e.g. mixture model, the option for reaction does not come.
Please suggest a way out.
Ozone"
