Benjamin Franklin & CFD - Cham

Philadelphia CFD ConferenceCombustion, turbulence and CFD;the population analogy (continued)April 2010Benjamin Franklin was a methodical man, andhe liked to express his ideas graphically.I. On the right, for example, is how herecorded each of his lapses from the strictmoral standards which he required ofhimself.[T=Temperance; S=Silence; O=Order; etc]I therefore imagine that he might have deviseda two-dimensional diagram so as to representinstructively the population of gas states,members of which might be found in acombustion chamber.It could have taken the triangular form on the left,with vertices representing pure air, fuel andcombustion products, respectively, with allpossible gas states, i.e. population members,between them.
