BOSfluids 7.0 released

DRG is pleased to announce the next release of BOSfluids, version 7.0. BOSfluids is our powerful fluid dynamic simulation tool to perform surge analyses, simulate pump failures and analyze waterhammer events in an interactive and visual way. The video below shows the highlights of the 2022 version 7.0. New features include: Support for building 2-D […]

BOSfluids capabilities in handling large models

One of the features that makes BOSfluids stand out from other surge analysis applications is its ability to deal with 3-D piping models. This, however, does not limit the size and complexity of the models that can be handled by BOSfluids. By employing a range of optimisation techniques you can comfortably build, view, modify and […]

BOSfluids 7.0: Support for building 2-D piping models

switch-between-2d-3d klein

The ability to work with 3-D piping models has always been one of the fundam ental features of BOSfluids. This not only sets BOSfluids apart from similar software, but also makes it possible to obtain more accurate results, especially if the flow conditions of interest are affected by the geometry of the piping system. On […]

Firewater Deluge Layout Design

Dynaflow Research Group has performed the design and analysis for the firewater deluge layout of two large production modules of a floating production storage and offloading system (FPSO). The objective was to design a safe, efficient and code compliant system, providing complete spray coverage by monitors and sprinkler nozzles for all areas and equipment that […]

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 […]

Upcoming BOSfluids release offers a steady state license option

BOSfluids is mostly known and used for transient flow analyses. However, it also provides a robust, fast and accurate steady state flow solver that can handle systems filled with liquids or gases. The upcoming BOSfluids 7.0 will offer a steady state license option that makes BOSfluids a very capable and cost-effective solution for the analysis […]

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 […]

BOSfluids: Two-phase flood and drain analyses

When an empty, or gas filled, piping system is rapidly filled with a liquid, then significant forces can be exerted by the liquid on the system, especially when the liquid hits a significant flow restriction or the end point of a pipeline section. Indeed, there have been multiple incidents involving firewater systems in which these […]

Coupled Thermodynamic BOSfluids-Jive Simulations

BOSfluids Thermodynamic Module BOSfluids is known for its steady state, quasi steady state and transient flow solvers and the more recent interface to the structural solver of ANSYS. Recently the steady state solver of BOSfluids has been extended with a thermodynamic module. That is, given thermal boundary conditions, BOSfluids calculates the temperature profile within the […]
