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 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 […]

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 […]

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 […]

BOSfluids: Improved pump model and user interface

Pump failure is a common cause of problematic transient flow conditions in piping systems. Simulation of pump failure is therefore an effective way to assess the robustness of a piping system before actual damage can occur. The pump model implemented by BOSfluids uses built-in pump curves to simulate the operating conditions of a pump after […]

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 […]

BOSfluids 6.2: Improved and more efficient user interface

The BOSfluids user interface has been improved in many visible and invisible ways in this new release. Although many changes are relatively small, together they make the user interface significantly more efficient when creating and modifying piping models. One change concerns the Piping tab page that requires less screen space so that more screen estate […]

BOSfluids: New support for simulating control systems

Piping systems frequently involve automatic control systems that adjust flow elements in response to changes in the flow conditions or to external events, such as timer switches. Setting up such control systems is a non-trivial task as the optimal control parameters tend to depend strongly on the piping system properties. Simulation is a very helpful […]
