Abstract:
V praksi se pogostokrat uporablja proces mešanja za najrazličnejše vrst tekočin, ki so lahko newtonske ali nenewtonske. Pri dimenzioniranju naprav za mešanje je pomembno določevanje potrebne moči za mešanje. Za nenewtonske tekočine, kot so dilatantne tekočine, je značilno, da je potrebna moč za mešanje odvisna od števila vrtljajev in tudi od viskoznosti, ki se pod vplivom strižnih napetosti spreminja. Predmet raziskave v tem delu je določevanje moči mešala za mešanje zmesi škroba in vode po postopku Rieger Novak. Meritve so pokazale, da je za različne gostote dilatantnih zmesi potrebna različna moč mešanja. Obravnavana zmes je izkazala lastnosti dilatantnih snovi.

Title:
Determination of the mixing power for non-newtonian fluid cornstarch-water mixture
Abstract:
In practice the mixing process is often used with different kinds of liquids, Newtonian or Non-Newtonian. The dimensioning of stirrers is important for the mixing power determination. Typical for the Non-Newtonian liquids, such as shear thickening fluids, is that the mixing power determination depends on shaft speed and viscosity, that depends on the influence of the shear stress. Subject of the research is determining the power of impeller for mixing the mixture of corn starch and water following the Rieger-Novak procedure. The measurements show that different mixing power determination is needed for different densities of shear thickening fluids. The mixture has shown the characteristics of shear thickening fluids.
