..., stability and breakup dynamics. Design/methodology/approach A numerical model coupling incompressible two-phase Navier–Stokes equations with electrostatic forces and charge transport is developed and experimentally validated. A comprehensive parametric study is performed over a wide range of operating...

...Karol Kaczmarski Purpose The purpose of this paper is to develop a numerical model of a steam pipeline connecting a boiler with a turbine, with an insulated outer surface. The temperature distribution inside the pipeline wall was compared when was perfectly insulated and when used real insulation...
