Abstract
The questions of theory related to the study of viscous fluid flow in a small clearances at large pressure differentials are remarkably interesting for practical implementation. These are studies of operation of devices with an uncompressed piston, hydroextrusion with an uncompressed press-washer, hydroextrusion with an uncompressed shank, processes of continuous hydraulic pressing with viscous fluid, analysis of leaks in hydraulic drive elements and other technological spheres. The article presents the results of analytical study of the nonisothermal flow of a viscous fluid in a thin clearance with one movable boundary. The mathematical model takes into account the change of the fluid viscosity caused by pressure and temperature in accordance with the exponential law, as well as the elastic deformations of the walls which limit the clearance, directly proportional to the fluid pressure in a layer.
