Development of Computational Fluid Dynamics (CFD) Analysis Dealing with Combustion

Through CFD analysis on chemical reaction, heat transfer, and flow, Tokyo Gas is making contributions to understand and improve the state of combustion, which leads to make gas appliances more energy-efficient and environmentally-friendly.

 

Combustion analysis-based equipment design

 
In order to encourage environmentally-friendly, energy-efficient use of commercial and industrial gas-fired equipment, Tokyo Gas performs computational fluid dynamics analyses based on combustion reaction, heat transfer and flow data. This practice helps to ascertain combustion conditions so that they can then be improved.
 
The use of CFD analysis allows us to conduct careful examinations and obtain data that is difficult to measure such as:
  • Temperature distribution inside the combustion chamber
  • Location and size of flame
  • Emission of CO and NOx

Incorporation of supercomputers and cloud computing

 
A multitude of physical phenomena must be taken into consideration when performing combustion analysis, and this can result in the calculations taking an enormous amount of time. Tokyo Gas makes use of outside computational resources, in the form of supercomputers and cloud services, to enable it to perform large-scale combustion analysis.

Perspective


In order to move towards the establishment of a low-carbon society, an increasingly higher level of technology is required in terms of combustion. Tokyo Gas has put in place a safe and energy-efficient combustion system which takes full advantage of combustion analysis technology to enable it to reduce carbon dioxide emissions derived from the combustion of city gas. For the future, Tokyo Gas is also developing new  combustion technologies that utilize hydrogen and ammonia, thus eliminating carbon dioxide emissions altogether.
