چکیده
With increasing level of polymer solution involvement in multiphase microdevice for for‐ mation of emulsion and fabrication of functional materials, it is of paramount importance to systematically understand the relevant physics of droplet formation in non-Newtonian fluids and how the material formation process may be affected due to the complex rheo‐ logical effect. The chapter aims to review and discuss the recent advances in technologies that enable fabrication and application of functional materials formed from non-Newtoni‐ an microfluidic multiphase system. Rheological behavior of polymer solutions and the mathematical models are reviewed. The influence of microstructure on rheological be‐ havior of polymer solutions and the fundamental physical phenomena driving non-New‐ tonian microfluidic multiphase system are discussed. Shear thinning and viscoelastic effect on breakup dynamics and droplet formation are presented. The microfabrication process of the device and synthesis of emulsion-templated materials with potential indus‐ trial and biochemical applications are elucidated.

متن کاملFinite Integral Transform Based Solution of Second Grade Fluid Flow between Two Parallel Plates
The importance of the slip flow over the no-slip condition is widely accepted in microscopic scaled domains with the direct impact on microfluidic and nanofluidic systems. The popular Navier Stoke’s (N-S) flow model is largely utilized with the slip flow phenomenon. In the present study, the finite integral transform scheme along with the shift of variables is implemented to solve the equation ...

Although there are many excellent ways presenting the principle of the classical calculus, the novel presentations probably leads most naturally to the development of the non-Newtonian calculus. The important point to note is that the non-Newtonian calculus is a self-contained system independent of any other system of calculus. Since this self-contained work is intended for a wide audience, inc...
