Question:
A journal bearing may be idealized as a flat plate with another flat plate moving parallel to the first and the space between the two filled by an incompressible fluid. Consider such a bearing with the stationary and moving plates at 10?C and 20?C respectively, the distance between them 3 mm, the speed of the moving plate 5 m/s, and engine oil between the plates.(a) Calculate the heat flux to the upper and lower plates, and(b) Determine the maximum temperature of the oil.GIVENJournal bearing: Two flat plates, one stationary, one moving with oil between themStationary plate temperature (Ts) = 10?CMoving plate temperature (Tm) = 20?CDistance between plate (H) = 3 mm = 0.003 mSpeed of the moving plate (Up) = 5 m/sASSUMPTIONSSteady stateConstant physical propertiesNegligible edge effectsOil isincompressible
