Terms of presence of liquid friction conditions

Abstract
The engineering practice shows that there are many bearings designed to operate in the field of hydrodynamic friction, but sometimes the oil film breaks and symptoms of wear appear on surfaces. We are interested in the possibility of determining these friction conditions under which the oil film effectively separates the two friction surfaces, and at the same time has a high load capacity and low friction. Parameters describing the selected range of hydrodynamic friction that interests us are as follows: pressure, sliding velocity, temperature and length of the slide at which the oil film not only is not interrupted, but still has a high load capacity and low friction. In this paper, we assume the boundary for the occurrence of hydrodynamic friction to be conditions under which a type of fluid friction changes into a kind of boundary friction. Establishing conditions in which one type of friction takes place helps to make conscious use of this fact to design a plain bearing with low friction and high strength non-interrupting film, and possible wear processes will occur only at moments of start-up and stop.
