MICRO PULSE MIXING- AN EFFICIENT MIXING METHOD OF SMALL QUANTITIES OF POWDERS

Mixing in crossflowing jets: Turbulence quantities

Simultaneous planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) yield measurements of two-dimensional jet fluid concentration and velocity fields, both the mean and fluctuating terms, in turbulent crossflowing jets. The jet-to-crossflow velocity ratio is r = 5.7 and the jet exit Reynolds number is approximately 5000. The measurements concern the developing region of t...

Numerical Investigation of Fluid Mixing in a Micro-Channel Mixer with Two Rotating Stirrers by Using the Incompressible SPH Method

Fluid mixing is a crucial and challenging process for microfluidic systems, which are widely used in biochemical processes. Because of their fast performance, active micromixers that use stirrer blades are considered for biological applications. In the present study, by using a robust and convenient Incompressible Smoothed Particle Hydrodynamics (ISPH) method, miscible mix...

Gas Mixing Simulation in a T-Shape Micro Channel Using The DSMC Method

Gas mixing in a T-shape micro mixer has been simulated using the Direct Simulation Monte Carlo (DSMC) method. It is considered that the adequate mixing occurs when the mass composition of the species, CO or N2, deviates below 1 % from their equilibrium composition. The mixing coefficient is defined as the ratio of the mixing length to the main channel’s height. As the inlet Kn increases, while ...

Standardized Micro-Scale Mixing Evaluation

The field of microfluidics has become increasingly important with the development of micro-fuel cells, DNA arrays, and various advancements towards the labon-a-chip concept. While researchers have proposed many methods of mixing, there has been no standardized comparison on the mixing efficiency of the proposed methods in literature. In this paper, the students implemented an image-based techni...
