The condensation of humid air is a crucial step in air conditioning and process engineering. However, the models that describe the condensation of vapour in the presence of a non-condensable gas require time-consuming numerical calculations that go beyond the Nusselt film theory. Only a small number of publications exist, where Read more…
Existing capillary tube models rely heavily on friction factor correlations, which enable the specification of the relative surface roughness. However, measuring the surface roughnesses of capillary tubes is a time consuming task, which requires specialized equipment. In this research we have developed a friction factor correlation, which does not Read more…
