Determination of Parameters That Control The Shear Thickening of Polymeric Fluids Containing Nano Particles
Shear-thickening ﬂuid (STF) is a novel colloidal dispersion whose viscosity can increase with increasing shear rate or applied stress. Under high shear rate, the viscosity of STF increases dramatically and the STF starts to behave as a solid-like colloid or material. The shear thickening phenomenon is fully reversible process, meaning that upon the removal of the external effects, namely the applied shear rate or stress, the STF returns back to its liquid-like natures instantly. Shear thickening is a non-Newtonian ﬂow behavior often observed in concentrated colloidal suspensions.
Control parameters of shear thickening behaviour is investigated in order to understand the origin of the shear thickening behavior, increase the processing performance of polymeric nanocomposites and design the optimized liquid armor system. Parameters that control sheaer thickening such as particle type, size, size distribution, shape, concentration, surface chemistry is being studied. Computational study with CFD (computational flow dynamic) methods is being studied to investigate the parameters effect shear thickening fluid during pipe flow and compare this results with experimental study.
