Modelling of mass transfer in film flow of shear thinning liquid on a horizontal rotating disk

A mathematical model for the mass transfer in radial nonwavy film flow of shear thinning power law liquid on a horizontal rotating disk has been assumed. Numerical simulations of the model are compared with experimental results for oxygen desorption from two water polymer solutions. It is established that the model underestimates the experimental mass transfer coefficients within the limits of the safety coefficients usually employed in the design of industrial equipment. Both the numerical and experimental data demonstrate a “synergetic” effect of the increase of disk revolutions and decrease of liquid rheology index in intensifying the mass transfer process.
