- Abstract
- The current study analyzes Langmuir slip boundary condition theoretically and
it is tested in practical numerical analysis for separation-associated flow.
Slip phenomenon at the channel wall is properly implemented by various numerical
slip boundary conditions including Langmuir slip model. Compressible backward-facing
step flow is compared to other analysis results with the purpose of diatomic gas
Langmuir slip model validation. The numerical solutions of pressure and velocity
distributions where separation occurs are in good agreement with other numerical
results. Numerical analysis is conducted for Reynolds number from 10 to 60 for
a prediction of separation at T-shaped micro manifold. Reattachment length of flows
shows nonlinear distribution at the wall of side branch. The Langmuir slip model
predicts fairly the physics in terms of slip effect and separation.
