BOSpulse 5.0: Improved model building user interface

The upcoming BOSpulse release, version 5.0, comes with a new set up of the first two top-level tab pages in the user interface. This change improves the distinction between the actions that operate on the main model and those that operate on a sub-scenario. This change makes it possible to skip the Scenarios tab page […]

BOSpulse: (Preview) New support for end caps

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 […]

Flow pulse of a rotary lobe blower compressor

Dynaflow performed an pulsation analysis study for a client where a silencer check was required to dampen the pulsations generated by a rotary lobe blower. A rotary lobe blower is a positive displacement pump which operates by pumping a gas with a pair of lobes. Gas is trapped in pockets surrounding the lobes and carried […]

BOSpulse support added to CSiPlant

BOSpulse support has been added to CSiPlant. As of version 7, CSiPlant is able to import the harmonic, pressure- induced forces calculated by BOSpulse. This means that you can use CSiPlant, and its non-linear transient capabilities, to assess the structural response of piping systems that are subjected to pressure pulsations resulting from reciprocating pumps and […]

BOSpulse: New support for generating torque graphs

The reciprocating compressor models implemented by BOSpulse require a substantial number of input parameters that affect the magnitude and shape of the generated flow rate. As the flow rate is the main source of the pressure pulsations, a small mistake in the input parameters can lead to an inaccurate or even invalid API assessment. To […]

BOSpulse 4.2 released

After the release of BOSfluids two weeks ago, DRG is pleased to announce the release of BOSpulse¬†version 4.2. BOSpulse is a comprehensive software solution for performing pulsation analyses of piping systems involving reciprocating equipment. Our software provides a complete solution for engineers looking for a tool to solve their acoustic and mechanical response problems for […]
