Abstract : When gas is sheared in torsional flow between two discs, one stationary and the other rotating, and when the distance between both discs is very small so that the velocity gradient is large, then the gas is drawn inside between the discs and a thrust bearing pressure is developed between them. The pressure at the centre of rotation, determined experimentally, was found to be independent of the speed of rotation and of the thrust on the rotating disc; its value was equal to the ambient pressure of the instrument. The values of the rigidity parameters of the gas were calculated. (Author)
