Damkohler number calculation
The Damköhler numbers (Da) are dimensionless numbers used in chemical engineering to relate the chemical reaction timescale (reaction rate) to the transport phenomena rate occurring in a system. It is named after German chemist Gerhard Damköhler. The Karlovitz number (Ka) is related to the Damköhler number by Da = 1/Ka. In its most commonly used form, the Damköhler number relates the reaction timescale to the co… WebNov 2, 2024 · The reaction kinetic rate and mass transport play an important role in the sizing and scale-up of reactors. The Damköhler's dimensionless number (D a) is the quotient of these effects.A new interpretation of D a as a local property is introduced D a (x, y, z, t).A new graphical methodology is proposed for the sizing and scale-up of …

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.
