Abstract Clustering of small rigid spherical particles into particle accumulation structures (PAS) is studied numerically for a high-Prandtl-number (Pr = 68) thermocapillary liquid bridge. The one-way-coupling approach used calculation the motion, modeling PAS as an attractor single particle. created by dissipative forces acting on near boundary due to finite size These can dramatically deflect...

to evaluate the flour quality 10 flour plants were selected in iran, tehran province. two kinds of flour were sampled from each plant (flour with 87% extraction named straight-run- flour as well as patent flour). samples were analyzed for their moisture content, ash, maximum viscosity of dough, particle size, falling number and the amount of damaged starch, which was determined through maltose ...

The stringency of vehicle exhaust emissions regulations resulted in a significant decrease particulate matter (PM) over the years. Non-exhaust particles (i.e., from brakes and tyres) account for almost half or more road transport-induced ambient PM. Even with internal combustion engine ban 2035, electrified vehicles will still emit PM brake tyre wear. Consequently, non-exhaust cannot significan...

ABSTRACT: Solid particle number emissions have been regulated in a wide range of automotive fields. Its technical regulations require annual calibration counting system because standard like span gas with known concentration does not exist. However, the fully ensure validity measurements during usage interval. This paper proposes methodology on-site checks generator so that its measurement valu...
