英语翻译
If different capillary diameters are used to study the mixture flows at the same temperature and the same wall shear rate conditions,the same viscosity values will be measured for the same mixture.
One needs only to regulate the applied pressure in different cases to maintain this rheologic condition.
To verify the mass conservation,one can obtain two curves in the μs-μf coordinate.
Each curve represents the possible choices for its own case.
The valid choices of viscosity values for solid and fluid phase in both cases are the intersections of the set of curves,see Fig.4.
Due to the mirror effect in formulation,only half of the curves corresponding to μs>μf is physically valid.
It is noticed that all the curves for different capillary diameters (or gaps)pass the same point if the temperature and wall shear rate remain in the same state.
So the intersection represents a valid choice for the viscosity values of solid and fluid phase in this specific rheologic state.
By a number of capillary tests under different rheologic states,collaborated with this analytical model,the variation of the corresponding viscosity values can be obtained according to the temperature and shear rate conditions.
These values are then the viscositv behaviours to be applied for each phase in a bi-phasic simulation on the basis of mixture theory.
This analysis shows also that the choice of viscosity values for different phases is generally independent of the value of interaction coefficient k.
One can observe that different curves change their shapes but pass always the same point.
So we can identify the viscosity parameters for each phase in an independent manner with respect to the interaction term k.
The method for determination of the bi-phasic viscosities may be furthermore modified in rheologic aspect.
Experimental data showed the so-called the slip phenomena at the wall in MIM injection .
The relevant research was carried out with a mono-phasic flow model and introduced into the simulation software .
These slip phenomena may be introduced in bi-phasic modelling with a new method for determination of the constitutive parameters.
