Flownex Simulation Environment 2023.1 v8.15.1.5364
Flownex Simulation Environment delivers technology that enables you to study how systems will behave in the real world, where fluid is the driving factor. Flownex system simulation relays the overall effect of changing specific properties on components, allowing clients to examine extensively all possible variations of a system in the design and optimization of systems.
Flownex Simulation Environment provides turbomachinery engineers with an easy to use, off-the-shelf tool for modelling combustion chambers, secondary air systems, blade cooling flows, lubrication systems with oil-air mixtures, as well as overall cycle integration and operation.
Blade Cooling By coupling 1D flow Flownex models with 3D heat transfer models in ANSYS Mechanical or CFX, a detailed turbine blade cooling simulation can be conducted. Flownex contains industry-standard pressure drop and heat transfer correlations for typical turbine blade features such as turbulator strips and pedestals. This allows designers to rapidly see the effects of their design changes on the maximum blade temperatures and cooling airflow rate.
COMBUSTION CHAMBER Preliminary combustor design requires that an extensive number of geometrical and operational conditions be evaluated and compared. Especially during this phase, Flownex is an essential tool for combustor design engineers as it accurately captures important parameters such as the mass flow rate distribution through air admission holes, associated pressure losses as well as liner wall temperatures. Networks can be easily configured and solved within a few seconds. This result in substantial development cost savings because of the reduction in the number of detailed 3D simulations and rig tests required. A further advantage is the ability to use the Flownex results as boundary conditions for subsequent localized 3D models.
LUBRICATION SYSTEM The primary use of Flownex in lubrication systems is used to determine optimum drain line sizes given the limited space inside the engine. This requires two-phase pressure drop calculations in lines with oil-air mixtures. In parallel with this engineers can determine whether or not scavenge pumps are required for fluid transportation in the drain lines and, if so, what the pumping requirement will be.
SECONDARY & COOLANT FLOW Flownex includes a comprehensive rotating component library for analysing the secondary air system of a gas turbine engine. This enables engineers to quantify the bleed air consumption and flow distribution through the entire system. Furthermore, coupling Flownex with Ansys Mechanical enables engineers to perform detailed thermal studies of critical rotating components. Flownex includes:
- Real gas models.
- Windage power calculation.
- Choking calculations.
- User-defined HTCs.

Thunderhead PyroSim 2023.3.1206
PyroSim – это пользовательский интерфейс для программы Fire Dynamics Simulator (FDS). Полевая модель FDS может предсказывать распространение дыма, температуры, угарного газа и других опасных факторов во время пожара. Результаты моделирования используются для обеспечения безопасности зданий при проектировании, определения безопасности существующих зданий, реконструкции пожаров при расследованиях, и помощи в тренировках пожарных. FDS – мощный инструмент для моделирования пожара, разработанный Национальным институтом стандартов и технологий (National Institute of Standards and Technology – NIST). FDS моделирует сценарии пожара с использованием вычислительной гидродинамики (CFD), оптимизированной для низкоскоростных температурно-зависимых потоков. Такой подход оказывается очень гибким, и может быть применен к различным пожарам, начиная от горения в печах и до пожаров на нефтяных танкерах. Также с помощью FDS может быть выполнено моделирование, не включающее горение, например, работа вентиляции в зданиях. Расчетная модель FDS и программа для визуализации Smokeview тесно встроены в PyroSim.
