Preferential Concentration of FreeFalling Heavy Particles

We present a sweepstick mechanism for heavy particles transported by a turbulent flow under the action of gravity. Direct numerical simulations show that these particles preferentially explore regions of the flow with close to zero Lagrangian acceleration. However, the actual Lagrangian acceleration of the fluid elements where particles accumulate is not zero, and has a dependence on the

Negative mass

In theoretical physics, negative mass is a type of exotic matter whose mass is of opposite sign to the mass of normal matter, e.g. 1 kg. Such matter would violate one or more energy conditions and show some strange properties, stemming from the ambiguity as to whether attraction should refer to force or the oppositely oriented acceleration for negative mass.

Measuring Cleaning Chemical Concentration CTG Clean

Jul 23, 20130183;32;pH and specific gravity are two common parameters that can be used to determine the concentration of cleaning chemistries in water. This blog explores ways in which pH and specific gravity can be measured to determine chemical concentration. pH pH as described in an earlier blog, is a measurement of the acidity or alkalinity of a liquid.
