Struct Fluid 

pub struct Fluid {
    pub density: Density,
    pub kinematic_viscosity: Diffusivity,
}

A Newtonian fluid.

Fields

density: Density

Density.

kinematic_viscosity: Diffusivity

Kinematic viscosity, μ/ρ, in m²/s.

The one that appears in the equations above and in every closed form below. Tables quote the dynamic viscosity as often as this one and the two differ by a factor of a thousand for water, which is the sort of error dimensions cannot catch and a name can.

Implementations

impl Fluid

pub fn water() -> Fluid

Water at 20 °C.

pub fn air() -> Fluid

Air at 20 °C and one atmosphere.

pub fn new(density: Density, kinematic_viscosity: Diffusivity) -> Fluid

A fluid with whatever properties, for a test that wants a convenient Reynolds number.

pub fn dynamic_viscosity(&self) -> f64

Dynamic viscosity, ρν, in Pa·s.
