Mass transfer with chemical reactions in fully developed turbulent pipe flows has been studied theoretically. The pipe walls are assumed to remain at a constant prescribed concentration. The effect of arbitrary reaction orders and of Reynolds and Schmidt numbers upon the transfer coefficients was investigated. Radial and longitudinal concentration profiles were obtained to show the effect of reaction orders and dimensionless rate constants. Effects of concentration levels on these phenomena were also studied and proven significant. The ratio of the transfer coefficients with chemical reactions to those without chemical reactions increases as a function of the downstream aspect ratio.
