Hi everyone,

I am currently investigating an operational problem with the drain line of high pressure feedwater heater in power station. It vibrated with high amplitude during operation.

This drain line is from high pressure heater working at pressure 1.8 MPa, drains to deaerator at 0.6 MPa, there are bend, T-shape welds, gate type isolation valve, control valve.

I suppose there are flashing at some point along the pipe, because the problem arise when the heater deteriorate following by the rise of drain water temperature.

I would like to be suggested how to build a model to investigate the flashing potential, specific with openFoam.

I appreciate your recomendations.
