Dec 01, 2008  Particle mixing measureThe method is flexible and can be used with both continuous and discrete particle distributions. A three-dimensional grid is constructed over all the particles. Local averages of a selected property (e.g. mass, density, diameter, colour) are calculated using all particles in the region centered at each grid point.

Assessing mixing characteristics of particle-mixing and ...

The mixing of particulates such as powders is an important process in many industries including pharmaceuticals, plastics, household products (such as detergents) and food processing. The quality of products depends on the degree of mixing of their constituent materials which in turn depends on both geometric design and operating conditions.

Numerical analysis of particle mixing characteristics in a ...

Mar 01, 2000  The effect of bed height on particle mixing seems considerable even though the rotational speed is the same. To make this point clearer, the mixing process is examined by tracking the tracer particles at three different regions, i.e., the top region of the bed, the middle region of the core section and the bed bottom region.

Mixing (process engineering) - Wikipedia

In industrial process engineering, mixing is a unit operation that involves manipulation of a heterogeneous physical system with the intent to make it more homogeneous.Familiar examples include pumping of the water in a swimming pool to homogenize the water temperature, and the stirring of pancake batter to eliminate lumps (deagglomeration).. Mixing is performed to allow heat and/or mass ...
