Abstract
A new modification of the asymptotic interpolation method is put forward, which uses the known two-sided asymptotics of the solution of a problem and the values of the function in an intermediate region. Special switching functions are suggested for joining the asymptotic solutions. Their constants are determined from their values at specified reference points. By way of an example, this method is applied to some problems of chemical hydrodynamics and mass transfer that have no exact analytical solution. Approximate solutions are obtained for the entire variation range of the characteristic dimensionless parameter. Their accuracy was estimated by collating them with the results of numerical computation.
