• Pressure drop showing a reversal of the value as the gas velocity decreases.
• Drag reduction occurring by the additional of a small amount of 25 to 50 μm particles.
• Reflux of solids when the pipeline is inclined and the velocity is not sufficient to fully transport the solids.
• Explosive nature of fine powder cautioning care in handling such materials.
• Unique particle motion with compliant particles and particle rotation of spherical particles in dense phase conveying.
This review will present a number of novel, unusual and new videos and picture that have been observed over the last four decades in our solids processing laboratory and others. The regimes of flow will cover both the dilute phase and dense phase pneumatic transport regions. The phenomena discussed are in general non-obvious ones. The non-obvious statement comes into play when competing physical processes interact in a non linear manner so that one's experience in solids processing of experimental observations is challenged.
