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 […]
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 […]
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 […]
Release ISOtracer 2.2
The next release of ISOtracer, version 2.2, is available. With ISOtracer you can model and mark up isometric drawings in a single operation. Simply trace along the piping on the drawings to create a 3-D model and position markers at the same time. This new version of ISOtracer includes the following improvements: New support for […]
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 […]
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 […]
BOSfluids 6.2 released
DRG is pleased to announce the next release of BOSfluids, version 6.2. 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 2021 version 6.2. New features include: New support for simulating […]
