Question
A 6 cm diameter arrow rotates at 3,000 rpm in a 20 cm long chumacera with a uniform clearance of 0.2 mm. In the stationary operating conditions, both the chumacera and the arrow in the neighborhood of the oil gap are at 50°C and the viscosity and thermal conductivity of the lubricating oil are 0.05 Pas and 0.17 W/m•K. By simplifying and solving the continuity equations, the momentum and the energy, determine the following:
A) The maximum temperature of the oil.
(B) The reasons for the transfer of heat to the
Chumacera and the arrow.
C) The mechanical power lost by dissipation
Viscose in the oil.
