Flowmaster V7 Gas Turbine brings the first commercial product to address the needs of Secondary Air and Fluid Mixing applications to the CFD system simulation market. With an integrated swirl solver engineers are able to calculate the swirl generated by rotating components in a gas turbine engine and geometrically induced swirl such as is generated by preswirl nozzles. Through the use of complex cavity components and cavity wizard, Flowmaster utilizes the swirl solver to simulate the secondary air systems of gas turbine engines. This capability is also flexible enough that it allows individual companies to customize the software to use their proprietary correlations for the flows through these rotating passageways. In addition, Flowmaster V7 Gas Turbine enables engineers to model the mixing of multiple liquids or gases, calculating the fluid properties of the mixture during the analysis. This is particularly useful when modeling steam injection in combustors and fuel systems of power generation turbines utilizing syngases.

The product also incorporates a catalogue of industry-tailored components, including labyrinth seals, rotating cavities, annular passages and specialized orifices, all of which are customisable. Users can build and customise their own component catalogues - reducing project time and improving the quality and repeatability of initial designs.

According to Mike Croegaert, Flowmaster’s dedicated Gas Turbine Product Manager, “This new version of Flowmaster will give gas turbine users unprecedented capabilities in secondary air modelling as well as the robust modelling of all gas turbine fluid systems that Flowmaster has historically been used for. This is the first time gas turbine companies will have a fluid system analysis tool specifically tailored to their needs, as well as having the ability to customise and integrate the software with other tools to create a “Best in Class” solution that fits their design processes.”
