The lubricant in the bearings of ships can be easily polluted by sea water. Too much water may deteriorate bearing performance and result catastrophic failure; therefore, should changed regularly to prevent this. It is important investigate effect adding mineral oil on tribological these bearings. In present study, different amounts 1, 2, 3 per cent (by mass) were mixed with a typical viscosity 46 mm 2 /s at 40 °C tested 12 identical journal under operation conditions rotational speed load. For each case, temperature within film, loci shaft centre, power consumption, emulsion measured. parallel measurements, CFD simulation was performed for test estimate friction force load capacity. experimental measurements computational predictions compared. A maximum amount that tole-rated established normal working bearing.
