National Combustor Code (NCC)–new software from NASA

Based on contacts made during the UFTO visit last year to NASA Lewis, we received an early notice about this soon-to-be announced Technology Opportunity. NASA has developed a major new combustion modeling code, and is looking for new areas that it can be applied. Private companies can submit problems. Terms and scope of an agreement would then be negotiated, giving the company a one year head start in evaluating the merits of seeking a commercial license.

A new software program – the National Combustor Code (NCC) – has been developed for aerospace and non-aerospace engineers and designers to enhance their understanding of physical and chemical processes which occur during continuous combustion. The NCC provides insight – for the first time – to the entire combustion process using a versatile and comprehensive set of tools. The National Aeronautics and Space Administration (NASA) seeks to transfer this multidisciplinary combustor design system to U.S. companies for advanced liquid and gaseous continuous combustion applications. The NCC utilizes computer-aided design (CAD) tools for geometry creation, advanced mesh generators for creating solid model representations, a common framework for fluid flow and structural analyses, and powerful tools for post and parallel processing. The National Combustion Code: A Multidisciplinary Combustor Design System

Potential Commercial Uses

• Evaluate the performance of current liquid and gas combustion systems leading to product improvement.

• Optimize the design of future liquid and gas combustion systems leading to increased performance and reliability.

• Examples of relevant liquid and gas combustion systems are:
– Aviation gas turbine engines
– Industrial/ground power gas turbines
– Industrial combustion devices involving continuous burning of liquids and gaseous fuels
– Hazardous waste incinerators
– Steel treating furnaces
– Domestic gas fired appliances


• Product improvement for current combustion devices with respect to efficiency and durability
• Reduced time and costs for the design cycle of future combustion devices
• Optimized performance and reliability for future combustion devices

The Technology

The development of the National Combustion Code was pursued under a NASA/Department of Defense/ Department of Energy/U.S. industry partner-ship. Recent efforts have been focused on developing a computational combustion dynamics capability that meets combustor designer requirements for model accuracy and analysis turnaround time, incorporating both short–term and long–term technology goals. As a first step, a baseline solver for turbulent combustion flows was developed under a joint modeling and code development effort between the Aero-Industry and the NASA Lewis Research Center. This baseline solver is a Navier–Stokes flow solver based on an explicit four-stage Runge– Kutta scheme that uses unstructured meshes and runs on networked workstations. The solver can be linked to any computer-aided design system via the Patran file system. Turbulence closure is obtained via the standard k–e model with a high Reynolds number wall function. The following combustion models have been implemented into the code: finite– rate reduced kinetics for Jet–A and methane fuels, turbulence–chemistry interactions via an assumed probability density function for temperature fluctuations, and thermal emissions of nitrogen ox-ides. The solver can switch between a parallel virtual machine (PVM) interface and a message-passing interface (MPI) by using compiler flags. Its parallel performance on several platforms has been analyzed, and on the basis of the results, several improvements have been made. To date, the baseline solver has been used in the following applications: simulation of swirling flow experiments, computation of a generic swirling flow can combustor, computation of a multi-shear low NOx fuel nozzle and calculation of a multi-walled production fuel nozzle, and calculation of a flame holder/Cyclone 1-cup sector.

Options for Commercialization

The executables of the National Combustor Code, Beta Version 2.0, and the corresponding nonproprietary source code will be available for release to the non-aerospace industry by summer 1999. Beginning in the summer of 1998, NASA would be willing to demonstrate the accuracy and reliability of the NCC by applying it to a wide range of areas where it would be helpful to have accurate predictions of the combustor process.

NACE – Int’l Corrosion Society

NACE Annual Conference and Exposition — CORROSION/98
March 22 – 27, 1998 San Diego, CA

See website at

A brochure for this conference came in the mail recently.


In the unlikely event that there could be people in your company who ought to be involved with NACE and aren’t, some background information is included below. (I checked with the NACE membership office, and several UFTO companies do have individuals who are members, though some have only one or two, and some have none.)

NACE is to corrosion what IEEE is to electrical engineering, and is one of those exceptional independent resources in a particular technical area of importance to the industry.

UFTO is developing information on other such resources as well.

New combustion system MERIT has smooth burn

Nikkei English News via Individual Inc. : (Nikkei Industrial Daily, May 6, 1997)

The Agency of Industrial Science and Technology’s National Institute for Resources and Environment reports progress in the design of a next-generation combustion system dubbed MERIT, for Mediator Recirculation Integrating Technology.

MERIT combines oxidation and reduction steps to minimize energy loss and the release of polluting emissions during fuel combustion. Fuel is not burned directly, but exposed to a circulating metallic mediator.

The method is said to be as much as 10% more energy efficient than conventional combustion systems which directly burn fuel. Moreover, no nitrogen oxides are released and pure carbon dioxide is easily recovered.

In the latest development, the institute succeeded in running smooth continuous combustion reactions in a small prototype system. The next step is to design larger facilities, with the aim of eventually introducing the technology to power-generating turbines and boilers.

The prototype system comprises a pair of reaction columns connected at the top and bottom. Metal particles are exposed to air in the first column and undergo a sudden oxidation reaction, generating heat of 1,000 C.

The now-oxidized metal particles are then moved to the second column, where they mix with fuel and undergo a reduction reaction. Once reduced, they can be transferred back to the first column and oxidized again. In this way, the circulating metal particles act as a mediator for an overall combustion reaction.

In the tests, nickel was used as the metal mediator, and both the oxidation and reduction reactions were completed in less than one-tenth of a second. By circulating the nickel particles at a high enough speed it was possible to run a continuous oxidation-reduction reaction.

The challenge now is to find metals with higher durability and to develop a way to control the oxidation reaction. With these research topics in mind, the institute said it plans to work with other research institutes and private concerns to develop a practical technology.
