Wall Viscosity in Flow inside tubes Formulas

Wall viscosity is the viscosity of fluid in near wall during the turbulent flow. And is denoted by μ_wall. Wall Viscosity is usually measured using the Pascal Second for Dynamic Viscosity. Note that the value of Wall Viscosity is always positive.

FAQ

What is the Wall Viscosity?

Wall viscosity is the viscosity of fluid in near wall during the turbulent flow. Wall Viscosity is usually measured using the Pascal Second for Dynamic Viscosity. Note that the value of Wall Viscosity is always positive.

Can the Wall Viscosity be negative?

No, the Wall Viscosity, measured in Dynamic Viscosity cannot be negative.

What unit is used to measure Wall Viscosity?

Wall Viscosity is usually measured using the Pascal Second[Pa*s] for Dynamic Viscosity. Newton Second per Square Meter[Pa*s], Millinewton Second per Square Meter[Pa*s], Dyne Second per Square Centimeter[Pa*s] are the few other units in which Wall Viscosity can be measured.
