The stability characteristics of a premixed, swirl-stabilized flame were studied to determine the. effects of hydrogen addition on flame stability under fuel-lean conditions. The burner. configuration consisted of a centerbody with an annular, premixed methane/air jet.
eigenvalue - (mathematics) any number such that a given square matrix minus that number times the identity matrix has a zero determinant. characteristic root of a square matrix, eigenvalue of a matrix, eigenvalue of a square matrix. value - a numerical quantity measured or assigned or computed; the value assigned was 16 milliseconds.
The word charge is often used as a synonym for both the generator of a symmetry, and the conserved quantum number (eigenvalue) of the generator. Thus, letting the upper-case letter Q refer to the generator, one has that [Q, H] = 0 implies that the eigenvalues (lower-case) q are time-invariant: dqdt = 0.
