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 eigenvalues of are the HÃ¼ckel molecular orbital energies , â¦,, expressed in terms of and , while the eigenvectors are the HÃ¼ckel MOs , â¦,, expressed as linear combinations of the atomic orbitals .
