- Under what conditions will a premixed flame (burning a hydrocarbon) be yellow?
- Under what conditions will a premixed flame have an inner and outer envelope?
- What is an approximate flame speed for a premixed stoichiometric methane flame?
- What is an approximate flame thickness for a premixed stoichiometric methane flame?
- Why are laminar premixed Bunsen flames triangular?
- How is the shape/angle related to the flame speed?
- For a given detailed premixed flame solution (for example, from Cantera/Homework), if you have the heat release and temperature profiles given, label Zone I (prheat) and Zone II (reaction).
- What is something you learned from the USBM video?
- What is the relationship between flame thickness and flame speed from the simplified analysis?
- Was this from the analysis using zone I or zone II or both?
- If have a fuel with double the reaction rate, by what factor do you expect the flame speed to change?
- By what factor do you expect the flame thickness to change?
- Does a smaller flame thickness correspond to a higher or lower flame speed? Why?
- Does pressure or temperature have a larger effect of flame speed?
