The Reynolds number for Couette flow is a dimensionless quantity used in fluid mechanics to characterize the flow regime in a specific type of flow known as Couette flow. Couette flow is a type of laminar flow that occurs between two parallel plates when one plate is moving and the other is stationary.
- Re: Reynolds number.
- ρe: Density of the fluid at the edge or at the boundary layer.
- ue: Velocity of the moving plate at the edge or at the boundary layer.
- D: Distance between the two plates.
- μe: Dynamic viscosity of the fluid at the edge or at the boundary layer.
