Reference number : GC-2017-Q1-00533, amendment number : , agreement type : G, recipient legal name : Devaud, Cecile (University of Waterloo), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Wolf Steel Limited, parent company of Napoleon, is looking to improve existing gas fireplaces and develop_x000D_
new products to meet the continuously increasing consumer market demand of efficient and clean heating_x000D_
products with an aesthetical aspect. Current design methods rely on empirical knowledge developed over many_x000D_
years for some specific burners. However, no systematic methodology based on rigorous combustion research_x000D_
has been derived that would be valid for any kind of burners and fuels. In addition to the complex chemistry_x000D_
involved in the formation of atmospheric pollutants, the desired optimal operation of gas fireplaces strongly_x000D_
depends on the burner design and amount of air available for burning._x000D_
The objective of the proposed research is to investigate the complex relationships between the burner geometry_x000D_
and operation variables and their resulting impact on heating value, flame appearance and atmospheric_x000D_
emissions. The proposed investigation will be conducted using Computational Fluid Dynamics (CFD) that_x000D_
provides detailed information at small turnaround times with much lower costs compared to experimental_x000D_
studies. The final results will provide detailed information on the fluid flow within the combustion chamber, as_x000D_
fluid can eddy back and contaminate the air supply to the burner, causing poor combustion and flame_x000D_
appearance. Further, using the simulations, a map of optimal operating conditions for heat output, atmospheric_x000D_
pollutants (carbon monoxide (CO), carbon dioxide (CO2), soot and nitric oxides (NOx)), and luminous flames_x000D_
based on a rigorous approach will be generated._x000D_
The proposed research will provide numerical results using CFD to improve the design and fundamental_x000D_
understanding of combustion processes in the context of fireplaces. The proposed work will be key towards_x000D_
providing Wolf Steel Ltd and their customers further leading-edge simulation tools in a highly competitive_x000D_
