Altair Flow Simulator 19.1 x64 一款集成的流量,傳熱和燃燒設計軟件

Flow Simulator是壹款集成的流量,傳熱和燃燒設計軟件,可實現混合保真度模擬,從而優化機器和系統設計。

Flow Simulator是用於分析通過流動管道網絡(有時稱為元件或電阻器,通常稱為元件)的穩態可壓縮和不可壓縮流體流動的計算機程序。

Flow Simulator創建用於燃氣渦輪發動機的設計,包括處理旋轉和靜止參考框架中的流動以及在參考框架之間傳輸流體的能力。由於流體的旋轉速度在燃氣輪機分析中是關鍵的,因此流動模擬器包括腔解算器,其計算角動量平衡。腔解算器連同旋轉元件,在切線方向上成角度的元件,渦流元件和渦流室可用於模擬旋轉流場。

Flow Simulator可以使用可壓縮氣體和不可壓縮液體作為工作流體。可壓縮氣體選項可以使用單壹物種或2種物質的混合物,例如空氣和蒸汽。可用的流體成分選項包括:作為理想氣體的空氣,單壹真實氣體,作為理想氣體的空氣與壹種真實氣體的混合物,以及兩種真實氣體的混合物。流動模擬器與NASA的CEA庫相連,以允許更壹般的氣體混合物以及反應流。

 Flow Simulator中提供的不可壓縮液體包括水,噴氣燃料和油。用戶還可以根據需要輸入自定義流體屬性。

Flow Simulator網絡由稱為“元件”的流動管道組成,這些流動管道連接在稱為“腔室”的節點之間。網絡的邊界由“邊界腔室”定義,“邊界腔室”具有固定的流體特性,例如溫度和壓力。流通過邊界室進出網絡。各種類型的元件可用於流網絡中。元件的選擇包括孔,管,泵,彎頭,閥門,噴嘴,密封件和渦流,用於旋轉流動,膨脹,收縮。所有元件類型都具有壹個上遊室和壹個下遊室。

Flow Simulator可提供四種腔室類型:壓力室,通過將動態項固定為零來消散流入流體的流體速度;動量室,其計算來自進入流的合成室流速(包括方向),並使用與下遊限制對齊的動壓力分量來驅動出口流;慣性腔,類似於動量腔,除了它在慣性(絕對)參考系中跟蹤流體特性,例如速度和總溫度,並允許在具有不同轉速的框架之間轉移。第四腔室類型,即渦流腔室,不與前三種腔室類型的元件連接。渦流室將數據存儲在絕對參考系中,並用作渦流和空腔的參考室。示意圖形式(由Flow Simulator GUI預處理器生成)的示例網絡顯示在下圖中。

Flow Simulator由腔室和元件網絡組成,這些元件具有限定的流體壓力,溫度,速度,流動方向和邊界腔室處的混合物分數。在模型中定義每個元素的流動阻力特性。內部(非邊界)腔室規定了壓力,溫度和速度的初始猜測值。為了完成輸入,包括壹組通用數據,其指定輸出文件要求,收斂容差和解決方案控制參數。該流體系統設計工具在單壹平臺內提供跨學科建模和優化功能,用於3D設計環境中的流體動力學/熱/燃燒的機器設計。該工具允許用戶導入實際硬件和3D CAD點雲的利用率,以自動創建覆蓋在機器硬件上的計算模型。擴展的預配置元件/組件庫可用於建模/模擬各種物理現象,包括可壓縮/不可壓縮流體流動,浮力驅動流動,旋轉腔體系統流動,傳導/對流/輻射傳熱,燃燒平衡化學和物種運輸。分析模式的八種組合(穩態,準穩態和流體動力學的瞬態分析,熱,可用於在循環/任務模擬(飛行任務,功率提升,關閉等)期間預測系統/子系統運行條件。控制系統組件(比例積分微分(PID)控制器,前饋和任務)可與計算模型系統/子系統集成,以優化循環/任務分析期間的模擬機器操作。

新版Altair Flow Simulator V18R版本是壹款集成的流量,傳熱和燃燒設計軟件,可實現混合保真度模擬,從而優化機器和系統設計。


Flow Simulator is an integrated flow, heat transfer, and combustion design software that enables mixed fidelity simulations to optimize machine and systems design.

This fluid system design tool provides interdisciplinary modeling and optimization capabilities within a single platform for machine design with respect to fluid dynamics/thermal/combustion within a 3D design environment. This tool allows users to import actual hardware and utilization of 3D CAD point-cloud to automatically create the computational model overlaid on the machine hardware. An extended library of preconfigured elements/components is available to model/simulate a wide-range of physical phenomena including compressible/incompressible fluid flow, buoyancy-driven flow, rotating cavity system flow, conduction/convection/radiation heat transfer, combustion equilibrium-chemistry & species transport. Eight combinations of analysis modes (steady state, quasi steady state, and transient analysis for fluid dynamics, thermal, and combustions) are available to predict system/subsystem run conditions during a cycle/mission simulation (flight mission, power ramp up, shut down…etc). Control system components (proportional integral derivative (PID) controllers, feedforward, and mission) can be integrated with computational model system/subsystem to optimize the simulated-machine operation during cycle/mission analysis.

Key Features & Benefits:
Fast and accurate mixed-fidelity (1D, 2D, and 3D) flow simulations that handle complex geometry and long transient missions. A flexible common platform that allows different groups to perform modeling with respect to their verticals and thus be combined to create system models.

Modern graphic user interface with the ability to overlay/integrate the 3D digital CAD with the analytical models. The GUI is geared for design where the Pre/Solver/and Post are all embedded in a single interface. The fully integrated optimization module provides the capability to quickly explore the entire design space within 3D modeling environment; system models can be parametrized based on flow configuration, shape, dimension, and thermal characteristics to achieve an optimal cost-benefit design.

Extended library of preconfigured elements/components leveraging a large set of publicly-available experimental data for pressure drop and heat transfer characteristics. This fully extensible platform provides customers the capability to integrate their own IP and element formulations seamlessly utilizing Python scripting.

Industry Applications
Flow Simulator can be used in many industries including aerospace, power generation, oil & gas power conversion, transportation, additive manufacturing, automotive, and others. Flow Simulator's capabilities cover a wide range of application within these industries including turbomachinery rotating cavity systems, secondary flow & engine sealing, combustor cooling, fuel/lube systems, and power plant piping networks. The software can also be used for renewable wind turbines and electrical generator cooling and thermal management. For additive manufacturing, it allows for heat exchanger design and optimization.
