NEW COURSE: How to Review a Pulsation Study
Recently Dynaflow Research Group together with online training platform EngineeringTrainer.com released “How to Review a Pulsation Study” training course. The course objective is to explain what the non-specialist reviewer or project lead should focus on when reviewing a pulsation analysis study. Pulsation studies can result in quite elaborate and complex reports with large output data […]
BOSpulse 5.0: New heat exchanger element type
The BOSpulse element collection has been extended with a new element type for modeling shell and tube heat exchangers.
BOSpulse: (Preview) Save time modelling with the new PSD generator
In the next release of our pulsation analyses software BOSpulse, version 5.1, we will introduce a new modelling tool to generate the elements that make up a complete Pulsation Suppression Devices (PSD) based on a limited number of input parameters.
BOSpulse: New node type for modeling end caps
BOSpulse offers a new Cap node type with which you can more accurately model Pressure Suppression Devices and therefore perform more accurate API 618 and API 674 analyses.
BOSpulse 5.0 released
DRG is pleased to announce the next release of BOSpulse, version 5.0.
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 […]
