The purpose of this work is investigation changes in hydrodynamic parameters (absolute pressure, mass flow rates solution and secondary steam, steam velocity, irrigation density, pressure loss) along the length heat exchange tube a vertical falling film evaporator. obtained data distribution were used design evaporators.

Steel-tube grouting technology has been widely applied in the slope control engineering. While anti-sliding performances of different connection modes grouted steel tubes still needs further investigation. In this paper, a large-scale model test was used to study influence three types pile connections, namely whole without connection, with reinforcement welded and casing on performance multi-st...

We discuss annular confinement for electrons on liquid helium surface induced by a tubular electrode submerged beneath the surface. For shallow layer above tube resulting potential has minimum off axis of tube. The symmetry transitions in ground-state driven external magnetic field can be resolved microwave spectroscopy provided that radii first and second Rydberg subbands vertical quantization...
