Abstract Liquid droplet impingement (LDI) erosion can never be caused when there is not any liquid droplet in a piping system. In this study, the liquid droplet generation from l iquid film formed downstream an orifice in a pipe was studied experimentally and visualized by using a high-speed camera. Water-air two-phase flow was supplied to the orifice and liquid film was formed in the recirculation region downstream the orifice. It was found from the experiment that the liquid film was entrained by the fas...

Visualization Experiment of High-speed Gas-liquid Two-phase Flow and Liquid Droplet Generation from Liquid Film downstream of an Orifice

In order to clarify the solid particle behavior in a piping flow, especially to that in the vicinity of channel wall, a water-circulation loop was fabricated for the evaluation of solid particle -liquid two-phase flow. Firstly, the inflow condition upstream into an elbow was evaluated by a flow visualization experiment adopting PIV method and almost fully-developed turbulent velocity profiles have been realized by inserting perforated plates in the flow straightener tank installed upstream of the elbow. Hou...
