The flow of oil (k=0.145 w/m. k, µ= 0.605 kg/m. s = 0.605 n. s/m2 ) in a journal bearing can be treated as parallel flow between two large isothermal plates with one plate moving and the other stationary. consider two such plates are separated by 0.7 mm thick oil film. the upper plate moves at a constant velocity 8 m/s, while the lower plate is stationary. the temperatures of the upper and lower plates are 40°c and 15°c, respectively. a. obtain relations for the velocity and temperature distributions in the oil. b. determine the maximum temperature and where it occurs, and c. the heat flux from the oil to each plate.
