Palierne equation
Palierne equation connects the
viscoelastic solid particles in viscoelastic fluids.[1] The equation is named after French rheologist Jean-François Palierne, who proposed the equation in 1991.[2]
For the dilute emulsions Palierne equation looks like:
where is the dynamic modulus of the emulsion, is the dynamic modulus of the continuous phase (matrix), is the volume fraction of the disperse phase and the is given as
where is the dynamic modulus of the disperse phase, is the surface tension between the phases and is the radius of the droplets.[1]
For the suspension of solid particles the value of is given as[1]
The Palierne equation is usually extended for the finite volume concentrations of the disperse phase as:[1]
