AME 436 Assigned: 2/15/08 Problem Set #2 Due: 2/22/08 at 4:30 pm in my office mailbox (OHE 430J) (email or fax to me at 213-740-8071 if you’re off campus, DEN students can also fax to the usual number) Note: some of the special symbols on this page seem to show up properly only with Internet Explorer and not other web browsers – gotta luv Microsoft… Problem #1 Using the Zeldovich equation for burning velocity (S L ), and typical “baseline” values of ambient temperature (T ), adiabatic flame temperature (T ad ), order of reaction (n) and activation energy (E), answer the following questions: a) How does the reactant temperature T affect S L , everything else (including the product temperature T ad ) held constant? That is, will a 10% increase in T cause a more or less than 10% increase/decrease in S L ? b) How does T ad affect S L , everything else (including T ) held constant? That is, will a 10% increase in T cause a more or less than 10% increase/decrease in S L ? c) How does the activation energy (E) affect S L , everything else (including T and T ad ) held constant? That is, will a 10% increase in E cause a more or less than 10% increase/decrease in S L ? d) How does the concentration of fuel in the reactants affect S L , everything else (including T and T ad ) held constant? That is, will a 10% increase in the concentration of fuel in the reactants cause a more or less than 10% increase/decrease in S L ? e)
