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.
Charges are often denoted by the letter Q, and so the invariance of the charge corresponds to the vanishing commutator [ Q , H ] = 0 {\displaystyle [Q,H]=0} , where H is the Hamiltonian. Thus, charges are associated with conserved quantum numbers; these are the eigenvalues q of the generator Q.
