Numerical Analysis of Helical Spiral Micromixer of Non-Newtonian Fluid

In numerous industrial applications, high-performance micromixers find extensive usage, particularly in processes where mixing at low Reynolds numbers and within the laminar regime is crucial. To enhance mixing efficiency, the physical principle of chaotic advection is often employed. This study is numerically investigating the helical spiral passive-micromixer (HSTM), with fast mixing at low axial length with the help of chaotic advection. Characteristic of flow ‘mixing index’ results compared with the helical spiral micromixer. Blood is the working fluid that has the rheological characteristic of non-Newtonian fluids. HSTM gave a higher mixing efficiency of 98.5% at a low blood flow rate, i.e., 0.00004 kg/hrs and 79.5% at ṁ = 0.014 kg/hrs. Also, we have analyzed pressure drops of the HSTM to anticipate the energy demands necessary to propel the fluid. Thus, HSTM has a wide application in fields like biochemistry and biomedical.
