Abstrakt:	The Navier-Stokes and heat- and mass-transfer equations are solved numerically for a sphere with uniform blowing over the surface in the Reynolds number range up to 20. A method of refining the boundary conditions far from the sphere is proposed in both problems. A difference scheme from other authors is used to solve the hydrodynamic problem, and an explicit difference scheme with a second order of approximation is used for the heat problem. It is shown that blowing diminishes the aerodynamic drag of the sphere and the temperature or concentration gradient at its surface, i.e., the heat- and mass-transfer intensity.
