Arc pressure and weld metal fluid flow whilst using alternating shielding gases Part 2 : arc force determination [PDF]
, 2013 The transient variation of the shielding gas present in the alternating shielding gas process produces a dynamic action within the liquid weld metal. Flow vectors opposite in direction have been reported due to the various forces acting on the weld metal

The calculation of multiphase flows in flowing parts of centrifugal pump
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The effect of gas content on the changing of head of a centrifugal pump is researched. The method of numerical hydrodynamic modeling is used for solving this problem. The using mathematical models are described and compared. The results of the simulation of fluid flow, which are depended on the air content, are presented.
