The mechanism of heat transfer enhancement across solid gaseous interfaces by corona wind directed towards the heat transfer surface is investigated. Corona wind may adequately be described by the Navier-Stokes equations of motion. The Coulomb ion drag forces transferred to the neutral gas background create corona wind. The corona current is a function of the applied voltage and the electrode gap geometry. The average wind is proportional to the square root of the corona current. THe corona wind velocity distribution is bellshaped with a maximum of 5 m/s. The electrokinetic conversion efficiency is of the order of 1 percent. The enhancement of heat transfer by corona wind is significant. Heat convection enhancement by up to 90 percent are measured. The enhancement of convective heat transfer by corona wind blowing on a heat transfer surface is proportional to the 0.3 power of the corona current. Enhancement of convective heat transfer is only due to the augmentation of the hydrodynamic flow of the air.
