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.
What does Eigen mean? I keep hearing about Eigen-things. It's the German word for own, as in its own, but that doesn't really explain much. An eigenvector is a vector that a linear operator sends to a multiple of itself (i.e. an element of its own span), and the specific multiple is called the eigenvalue. Everything else that's called an eigen-whatever is so called because it's either an eigenvalue or eigenvector of some linear operator.
