Damkohler number calculation
WebThere are several Damköhler numbers, and their definition varies according to the system under consideration. For a general chemical reaction A → B of n-th order, the Damköhler number is defined as where: k = kinetics reaction rate constant C0 = initial concentration n = reaction order t = time and it represents a dimensionless reaction time. WebFor large values of the Damkohler number then there is complete conversion along the streamlines off the center streamline so that the conversion is determined along the pipe axis. 4A.3 Segregation Model …
