In a theoretical point of view, a stagnation flow is characterized by its viscous flow-like behavior due to its very low inertial contribution.53,54 The flow stagnation can be quantified by comparing the inertial term, ρa(u·∇u)⁠, and the viscous term, μa∇2u⁠, in the Navier–Stokes equation, yielding the inertial-viscous ratio as where ρa is the air density, u is the flow velocity, and μa is the air viscosity.
