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.
Use of the formula to define the logarithm of complex numbers. Now, taking this derived formula, we can use Euler's formula to define the logarithm of a complex number. To do this, we also use the definition of the logarithm (as the inverse operator of exponentiation) that.
