The influence of the compressibility of a viscous gas 
flowing around a cylinder with a circular cell on the mechanism of 
decreasing the drag of the cylinder by suction of air through the 
withdrawing slot channel in the cell was estimated based on the solution 
of the stationary Reynolds equations closed using the model of shear-stress 
transfer, the continuity equations, the energy equation, and the equation 
of state.
