In this example, the simulation was used to determine the total force exerted by the passing slug on the individual piping sections. The slug breaks up as it passes through each fitting, reducing the peak loads and distributing the liquid.
The time history of the individual XYZ force components can be determined, providing accurate data for piping stress analysis, mechanical and structural design. The forces can be accurately determined for a range of flow regimes avoiding excessive conservatism associated with traditional assumptions.
The total force exerted by the passing slug at each section is plotted against time. The slug breaks up as it passes through each fitting, reducing the peak loads and dispersing the liquid.
