摘要
Hydrodynamic lubrications between two plane plates with an intersection angle θ have been investigated us- ing the boundary slippage theory, and relations are obtained between dimensionless pressures and coordinate x, between bearing capacity, friction force, friction coefficient and di- mensionless slipping size factor. The results show that bear- ing capacity of two plane plates without boundary slippage significantly increases with increasing intersection angle θ when 0 〈 θ 〈 1°, whereas decreases with increasing in- tersection angle 0 when θ 〉 1°. The results also show that negative pressure occurs in fluid entrance region and bearing capacity decreases, and friction force and friction coefficient increase with the increase of dimensionless slipping size fac- tor.
