For the reliable design of dense-phase pneumatic conveying systems, an accurate estimation of the blockage boundary condition or the minimum transport velocity requirement is of significant importance.
For the reliable design of fluidized dense-phase pneumatic conveying systems, it is of paramount importance to accurately estimate blockage conditions or the minimum transport boundary.
An existing method of representing minimum transport criteria (based on superficial air velocity and solids loading) has been found inadequate for accurately predicting the unstable boundary, especially under diameter scale-up conditions.
The physical significance of Froude number in representing the minimum transport boundary is also discussed.
These transport conditions also influence generation of shear forces.
Transport conditions of clinical samples (4°C, no transport medium, 24 48 h) are not restrictive.
Unfortunately, information regarding transport conditions is missing (average time, temperature).
Szpunar's assessment is that Uber "exerts control over all the relevant aspects of an urban transport service" — from price, to minimum safety conditions, to accessibility of transport supply, to conduct of drivers and access to the service.
Reynolds number at minimum fluidizing condition.
