The upcoming version of BOSpulse will offer a new Cap node type with which you can more accurately model Pressure Suppression Devices (PSDs) and therefore perform more accurate API 618 and API 674 analyses.
Modeling the acoustic length and volume of the piping system is of great importance for an API 618 or API 674 analysis, especially when it comes to the modeling of PSDs. PSDs are often composed of large-diameter cylinders and ellipsoidal or dished end caps. These caps extend the volume of a PSD and thus affect the acoustic resonance modes of the PSD.
In earlier versions of BOSpulse one had to calculate and add the cap volumes manually to the model by inserting or elongating elements. This manual procedure is no longer necessary in the upcoming BOSpulse 5.0 as it will provide a new Cap node type that can model both ellipsoidal and dished caps. The Cap node automatically increases the length and volume of the attached PSD based on the specified geometry of the cap. It can also impose a reflection coefficient to account for acoustic losses at an end cap. The Cap node can therefore increase the accuracy of your API 618 and API 674 analyses.
