The Kutta-Joukowski theorem determines lift as the product of upstream velocity, fluid density, and circulation. Flow visualization experiments of cylinders in a cross flow demonstrate this effect. For comparison purposes, a classical potential solution is presented with the same parameters (with the Reynolds number of 920). The present study assumes that similar effects can be created by means of a non-symmetrical heat/mass transfer from a section of the bluff body. A theoretical model was derived, based on equations of momentum, mass, and energy balance.
