I performing combustion in two different atmosphere I want to observe the affect of replacing N2 with CO2 in combustion in solid fuels
I am dividing my research into three parts:
1- Kinetic study ( Different kinetics approach)
2- Synergistic affects
3- Heat and Temperature profile affect ( CFD modeling)
I am just wondering if I want to study the effect of CO2 to oxygen. ( oxygen diffusion, oxygen activity). What is the best computational modelling approach can help me with this and how I can relate this to kinetics and CFD modeling.
I already performed expirrement in pure CO2, O2/N2 and O2/CO2
Is DFT and MD is suitable options?

Hey there Ahmad Alsuwaidi,
That's a fascinating research direction you're pursuing! Let me break down your questions and approach them systematically.
1. **Kinetic Study:**
For examining different kinetics approaches, you Ahmad Alsuwaidi might want to consider using computational methods such as quantum chemistry calculations or transition state theory to investigate reaction mechanisms and rate constants. Density functional theory (DFT) could be a suitable option here for providing insights into reaction pathways and energy profiles.
2. **Synergistic Effects:**
Understanding the synergistic effects of replacing N2 with CO2 in combustion reactions could involve molecular dynamics (MD) simulations. MD simulations can help elucidate how molecules interact and influence each other's behavior in complex systems like combustion.
3. **Heat and Temperature Profile Effect (CFD Modeling):**
Computational fluid dynamics (CFD) modeling is an excellent choice for studying heat and temperature profiles in combustion processes. By simulating fluid flow, heat transfer, and chemical reactions, CFD can provide valuable insights into the thermal behavior of your system.
4. **Effect of CO2 on Oxygen (Oxygen Diffusion, Oxygen Activity):**
To study the effect of CO2 on oxygen diffusion and activity, a combination of computational techniques may be beneficial. DFT calculations can help predict oxygen diffusion rates and assess the impact of CO2 on oxygen activity in the system.
5. **Relating Computational Modeling Approaches:**
Integrating DFT calculations with MD simulations and CFD modeling can offer a comprehensive understanding of the combustion process. DFT provides atomic-level insights into chemical reactions and energetics, while MD simulations capture molecular dynamics and interactions. CFD complements these by simulating macroscopic flow and heat transfer phenomena.
Regarding your question about the suitability of DFT and MD, both are indeed viable options depending on the specific aspects you Ahmad Alsuwaidi aim to investigate. DFT can provide electronic structure information and reaction energetics, while MD can offer insights into molecular dynamics and thermodynamics.
In conclusion, leveraging a combination of computational modeling techniques like DFT, MD, and CFD can provide a robust framework for studying the effects of CO2 on oxygen in combustion reactions, as well as understanding kinetics and temperature profiles. It seems like you're on the right track with your research. Keep up the excellent work, and feel free to reach out if you Ahmad Alsuwaidi need further assistance or insights!
