Pool boiling on horizontal tube, evaluation of ten correlations [PDF]

Archive of Mechanical Engineering, 2023
The heat transfer coefficient during the pool boiling on the outside of a horizontal tube can be predicted by correlations. Our choice was based on ten correlations known from the literature. The experimental data were recovered from the recent work, for

Plug conveying in a horizontal tube [PDF]

Granular Matter, 2006
Plug conveying along a horizontal tube has been investigated through simulation, using a discrete element simulation approach for the granulate particles and a pressure field approach for the gas. The result is compared with the simulation of the vertical plug conveying.
