Deformable-drop dynamics near an airfoil surface in viscous air. (English. Russian original) Zbl 1161.76409

Fluid Dyn. 37, No. 5, 825-833 (2002); translation from Izv. Ross. Akad. Nauk, Mekh. Zhidk. Gaza 2002, No. 5, 180-190 (2002).
Summary: A locally monodisperse “air-supercooled water drop” flow past an airfoil is studied. The influence of the viscous boundary layer on the force exerted on the drops by the carrier gas and the effect of deformation of the drops on (i) their trajectories, (ii) the water mass flux density over the airfoil surface, and (iii) the wetted-surface length are considered. The effect of an airfoil electrostatic field on the dynamics of charged atmospheric drops is estimated. The role of the governing parameters, i.e. the airfoil angle of attack, the radius of the undisturbed spherical drop, and the drop charge is investigated.
The possible origins of the discrepancy between the numerical and experimental results of foreign researchers are indicated.
