Experimental and numerical study on the flow characteristics of slug flow in a horizontal elbow

Journal of Pipeline Science and Engineering, 2022
: Elbow is one of the most accident-prone locations in multiphase flow lines, and understanding the flow field is the key to manage the risk. In the meantime, the flow characteristics of slug flow are most complicated in the flow field.

Patterns of cell movement within the Dictyostelium slug revealed by cell type-specific, surface labeling of living cells [PDF]

, 1994
There are cells acattered in the rear, prespore region of the Dictyostelium slug that share many of the properties of the prestalk cells and that are therefore called anterior-like cells (ALCs).

Thermal exchange effects on steel thixoforming processes [PDF]

, 2010
Steel thixoforging is an innovative semi-solid forming process. It allows the manufacturing of complex parts and minimises the forming load. This work aims to identify and characterise the main feature zones of a thixoforging part.
