Gas Turbines

Flowmaster V7 Gas Turbine is a dedicated product developed specifically for your industry.

Gas Turbine tailored components and modelling toolsFlowmaster V7 Gas Turbine catalogues & components

Flowmaster V7 Gas Turbine provides you with an industry tailored catalogue of gas turbine components on top of the existing comprehensive library of standard fluid and thermal components available in Flowmaster. These components include labyrinth seals, rotating cavities, annular passages and specialised orifices, all of which are customisable.

You will also benefit from having the specialised secondary air graphical interface. This wizard has been specifically designed to aid in the input of the complex geometrical characteristics required to model the rotating flow that occurs in cavities formed in the rotor and stator disks.

Advanced analysis tools for the Gas Turbine industry

By investing in Flowmaster V7 Gas Turbine you not only have access to Flowmaster’s existing set of powerful analysis tools which include steady state, transient, incompressible and compressible, you also benefit from additional advanced Gas Turbine specific analysis tools:

Swirl Solver

Flowmaster V7 Gas Turbine has an integrated swirl solver in its analysis capabilities. This solver calculates the swirl generated by rotating components in a gas turbine engine and geometrically induced swirl such as is generated by preswirl nozzles. It also tracks how the swirl is propagated downstream and how it is either enhanced or degraded by the other components downstream.

Secondary Air

Through the use of complex cavity components and cavity wizard Flowmaster utilises the swirl solver to simulate the secondary air systems of gas turbine engines. This is the air flow through and between the rotating and stationary disks that are attached to the rotor and stator blades. This capability is also flexible enough that it allows individual companies to customise the software to use their proprietary correlations for the flows through these rotating passageways.

Fluid Mixing

Model the mixing of multiple liquids or gases. Flowmaster will calculate the fluid properties of the mixture during the analysis. This is useful when modelling steam injection in combustors and fuel systems of power generation turbines utilising syngases.

Many of today’s leading gas turbine manufacturers use Flowmaster to test designs and run simulations earlier in the development process to reduce prototyping costs, improve quality, promote repeatability of designs and ultimately speed up gas turbine system development. Customers include: Kawasaki Heavy Industries, GE, Siemens, Mitsubishi Heavy Industries, Hitachi and Alstom. Typical systems analysed include:

  • Turbine Blade Cooling
  • Secondary Air Systems
  • Atomising Air Systems
  • Combustion Liner Heat Flow
  • Lubrication Systems
  • Fuel Supply System

Case Studies

Siemens and Flowmaster working together - for enhanced secondary air systems

Flowmaster is successfully applied for the prediction of flow rates, pressures and temperatures in Siemens' gas turbine secondary air systems. Calculation methods and correlations were developed for the secondary air flow through the rotating blades. Flowmaster has been extended by writing ECMs to make it applicable for this. This work has resulted in a design model that enables complete cooling and sealing air flows to be studied.
