In this work, the authors study the influence of the Reynolds number on the heat and mass transfers in an interface air- water of a parabolic pond of retention full of water in forced convection. The free surface of the pond is crossed by a forced warm air. In the water, the vorticity-stream function is adopted. To resolve the equations in the air which are constituted by a mixture dry air and of steam, the hypotheses of laminar boundary layers thermal, mass and dynamic are adopted. The dimensionless equations are resolved by the finite difference method with an implicit scheme for the time. The author has analyzed the influence of the Reynolds number on the parietal value. The obtained results are calculated for numbers of Reynolds varying from 200 to 2000.
