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 determinant of a triangular matrix is the product of the diagonal entries. Eigenvalues of triangular matrix are the entries on main diagonal. If A is an m x m triangular matrix, then its eigenvalues are the entries on its main diagonal.
