Popis:	An experimental study was performed on the effect of forced convection of heated air on the velocity inside a hanging drop of salt solution. It is shown that when modeling the convection velocity inside the droplet, it is necessary to take into account the determining key factors: forced air flow velocity U1 (dynamic factor); the thermal (thermal factor) and the solutal Marangoni numbers (MaT and MaC). The velocity component of the thermal factor can either exceed or be less than the velocity component of the dynamic factor. The convection velocity in the drop is proportional to the radius of the drop to the power of 0.5. Velocity in a drop of salt solution measured using the Particle Image Velocimetry method.
