Pressure wave damping in branched pipes with arbitrary angles

Strong pressure waves may occur frequently as undesired phenomena leading to high loading on piping systems of nuclear power plants and chemical industries. This is occasionally observed when piping systems of different pressures are suddenly and unforeseenly connected together producing pressure or...

Description
Summary:Strong pressure waves may occur frequently as undesired phenomena leading to high loading on piping systems of nuclear power plants and chemical industries. This is occasionally observed when piping systems of different pressures are suddenly and unforeseenly connected together producing pressure or even shock waves. For an unsymmetrical branched channel, as a simple geometrical model of a complete piping system, the attenuation of shock waves is calculated. This calculation is based on the fluid-in-cell method for an unsteady, two-dimensional flow. The results agree with experiments and serve as a check for the applicability of earlier models.
