Abstract
This work investigates and analyzes the performance of
conventional slip models among various regimes of Knudsen number
and developes a new multicoefficient slip-velocity model, by using
Taguchi quality control techniques and numerical analysis. A
modified Reynolds equation is also derived based on the new
slip-flow model. The multicoefficient slip model and its
slip-corrected Reynolds equation are suitable to a wide Knudsen
range from slip to transition regime. In comparison with other
conventional slip models, it is found that the current results
have a better agreement with the solution obtained from the
linearized Boltzmann equation and direct simulation of Monte Carlo
method (DSMC).
