Application: CFD Leads to Successful Design of Gas-Fired Preheater

ANSYS FLUENT by Serguei Nester, Principal Combustion Engineer, and Joseph Rabovitser, Assistant Director
Gas Technology Institute
Des Plaines, Illinois

Computer simulation saved more than $100,000 dollars in the design of a new coal preheating technology for low NOx burners by making it possible to get the design right the first time. The Gas Technology Institute (GTI) is developing a NOx reduction process under a cooperative agreement with the Department of Energy to provide a cost effective, combustion-based alternative to selective catalytic reduction (SCR). Development targets include NOx reduction to below 0.15 pounds per million Btu, reduced CO2 emissions, and a 55% electricity cost reduction compared to SCR. The technology combines GTI’s Methane de-NOX reburn technology with a pulverized coal (PC) preheating approach developed for utility pulverized coal combustors by the All-Russian Thermal Engineering Institute (VTI). Many variations of the initial burner design were evaluated using computational fluid dynamics (CFD), making it possible for engineers to determine an optimized design concept. As a result, the initial prototype met the design objectives, eliminating the need to build and test additional prototypes at a cost that would have probably run into six figures each.

New Software: IcePro 3.0 is Released

Fluent Inc. has announced the release of IcePro 3.0, its Pro/Engineer®-to-Icepak interface. The interface builds on its successful integration of CAD software with the thermal modeling software Icepak.

This release is an advance in the CAD integration paradigm introduced in the previous versions of the interface. By allowing the user to use simplification tools available in Pro/Engineer itself, the time required to get thermal models from CAD systems is reduced dramatically. The philosophy of the integrated Pro/Engineer CAD interface is to take advantage of design engineers' expertise in using Pro/Engineer to define the thermal model,
-- Icepak Product Manager, Dr. Rajesh Nair.

The IcePro user can take advantage of many of Pro/Engineer's CAD and database features, such as single instance exporting of repetitive features. The interface allows the user to load an assembly, and export specific parts or sub-assemblies to Icepak. The export mechanism also allows the user to capture non-geometric information.

IcePro 3.0 is now available from Fluent Inc for Windows NT/Windows 2000 platforms only, for Icepak users worldwide for an annual license fee of $2,500. The product will be made available on UNIX platforms at a later date. Visit the Icepak web site and the Fluent web site for a listing of worldwide offices and distributors.

New Software: Unified Process Management System for CFD codes
Posted Thu April 18, 2002 @05:54PM

NASA Khaled S. Abdol-Hamid writes:

The Unified Process Management System (UPMS) is a valuable CFD tool that utilizes NASA’s CFD codes: PAB3D, CFL3D and TLNS3D.

Each of these CFD codes has a specific format for input files. So far, the choice of a particular CFD code depends upon its reliability, its ease of use and the availability of technical support. However, it is difficult to find a CFD code that combines all of these requirements. Simple modifications in problem definition often require extensive alterations to these formats. Often, users must be trained by CFD code suppliers to enable them to model the problem correctly, and to use the available options in the code efficiently. Familiarization with more than one code becomes difficult.

The UPMS alleviates these difficulties with the use of an expert Graphical User Interface (GUI) system. The system also includes interactive adaptive grid capabilities and grid modification processes. The significance of this work is its flexibility in allowing these CFD grid structured codes to be coupled with the UPMS without any modifications whatsoever to the CFD solvers. It automatically generates documentation of code-independent project/ problem setup in engineering terms.

The UPMS was written in the object-oriented and highly portable JAVA programming language. The project is completed under fund from SBIR. You can get your copy of UPMS from
