1D Meanline Modeling

TurboTides 1D Meanline Module for Compressors, Pumps, and Turbines

The 1D Meanline capability calculates meanline-averaged inlet/outlet thermodynamic conditions and velocity triangles for each element in the flow path and predicts overall design-point and off-design performance of one or any number of stages.

Based on the design condition provided by users, 1D Meanline can perform preliminary geometry design and generate a valid starting flow path geometry.  An easy three-step TurboTides Design Wizard helps even a new user arrive at a good starting design using TurboTides' built-in design rules for different turbomachine classes and applications.

The Data Reduction capabilties of TurboTides 1D Meanline allow either experimental data or CFD results to be used for refining meanline modeling parameters to yield very accurate predictions of stage performance over the full range of operation and not only at the design point.  

A validated meanline model helps users to plan optimization strategies for all stages together, or within a single stage or single component of a stage, and provides reliable performance predictions for similar designs. Components can then be further studied or optimized using CFD.

Geometry Modeler


The Geometry Modeler is used for the design of any kind of radial, mixed-flow, and/or axial turbomachinery, including pumps, compressors, and turbines of all kinds. 

Using the modern, intuitive graphical user interface, users can easily edit and modify flow path components.  Feedback from 2D throughflow and blade-to-blade flow analysis allows the designer insight into the impact of changes to the flow path contour, blade shapes, or other design parameters.

The Geometry Modeler is the “hub” of TurboTides, connecting the core functions and ensuring all design and simulation methods access the same, unified geometry model. It can generate default 3D geometry from the 1D Meanline and generate a 1D model from a 3D geometry model, either one imported from CAD or one generated natively in TurboTides

When the Geometry Modeler is used with the CFD, FEA, and optimization, the optimized geometry will be available within the geometry modeler and stored in the TurboTides Knowledgebase. 

2D Flow Analysis



2D throughflow and blade-to-blade analysis is used to get nearly immediate feedback on design changes as the blade rows and other flow path elements for a single component, full stage, or multiple stages are designed. For axial compressor and turbine airfoils, flow conditions can vary sufficiently from hub to tip something more detailed than a meanline model is required.  

TurboTides 2D flow analysis automatically generates the grid according to the existing geometry model. The solver then solves the 2D Euler equations (by adopting empirical models) to get velocity and thermodynamic parameters of the 2D flow field. During through flow design,  The 2D flow analysis can be used in combination with the geometry modeler and optimization capability to adjust airfoil shapes to meet an objective function based  2D flow field results.

A validated 2D throughflow model can complete calculations and analysis for an axial compressor or turbine with more than 10 stages in very short time and can provide predictions to new working conditions or modified designs in a very short time.  Individual blade rows or multiple stages can then be optimized using CFD.


CAD Import/Export



TurboTides provides powerful Input/Output functions for widely-used 3rd-party CAD formats.


After importing external CAD models, TurboTides captures the key features (main blades, splitter blades, fillets, edges, etc.) of the original model and then reconstructs the parametric model for the components accurately and reliability. 

The imported models can be easily used for multiple purposes:

  1. Geometry modification and adjustment.  Once imported, users can use the rich functionality of the Geometry Modeler to refine and adjust the model as needed.
  2. Generate a 1D Meanline model and conduct performance analysis quickly in 1D Meanline.
  3. Perform full 3D CFD analysis and optimize the flow path based on CFD results.
  4. Analyze using 3D FEA for stress, thermal, and/or modal analysis.
  5. Consolidate the geometry and its performance data to generate records in the TurboTides Knowledgebase. The records can be easily utilized for future applications and analysis.

TurboTides can also export the 3D model to 3rd party CAD formats for manufacturing or for further detailed analysis.  

3D CFD Analysis


TurboTides CFD analysis is turbomachinery-specific and allows preprocessing, solving, and post processing all through a single, easy to use interface.

Based on the detailed 3D geometry generated by the Geometry Modeler, TurboTides CFD can generate structured or unstructured grids automatically to simulate main flow path or flow path branches.  If necessary, users can optimize and adjust the grid.

The core of TurboTides' embedded CFD capability is a pressure-based, implicit, unstructured solver developed by the TurboTides team, which can solve incompressible flow and both subsonic and supersonic compressible flow. The solver adopts acceleration technologies such as AMG and Open MP parallel calculations to provide useful results quickly. With sufficient validations, the result of this solver are comparable to standalone CFD packages while being much easier and less time-consuming to learn and use.

TurboTides CFD provides rich functions for turbomachinery-specific postprocessing, including grid parameter reports, flow field display, analysis reports, time-averaged or flow-averaged quantities, etc. 

3D FEA Analysis

TurboTides Integrated 3D FEA Module for Linear Stress, Thermal, and Modal Analysis


TurboTides' FEA analysis can perform structural analysis, thermal analysis, modal analysis of blades and disks.

Based on 3D model generated by the Geometry Modeler, TurboTides' can generate non-structured grids of blades and disks automatically. If necessary, users can adjust or optimize the grid. The FEA function can extract wall boundary conditions from 1D Meanline or 3D CFD automatically. Meanwhile, it also provides post processing functions including stress and strain display, vibration analysis report, etc.

FEA analysis in TurboTides is so fully automated that it can be looped into an optimization process together with cycle, 1D Meanline, geometry generation, and either 2D or 3D CFD to allow a design to be optimized while remaining within specified structural constraints for stresses or natural frequency margins.


TurboTides' Unique Knowledgebase Module to Document and Reuse Designs and Design Knowledge


One of the most unique features of TurboTides, the Knowledgebase provides users a platform to accumulate design experience and technology.  

Conventional turbomachinery design tools assume you will design each and every stage from scratch.

TurboTides instead includes a purpose-designed Knowledgebase so you build on your success:

  • Digitize both existing and new designs: store and manage designs and design approaches to support future R&D plus reduce design costs and risks. 
  • Allow stored designs to be used as “building blocks” or a starting point for new designs: Create new designs with higher confidence. 
  • Access your past design knowledge during the design process. Build on your success. 
  • Advance your design capabilities: Find user’s design methods and criteria by analyzing what is in your knowledgebase
  • Preserve organizational knowledge.  
    Don’t lose it when people retire, quit, die, or change roles. 

The accumulation of design experience is essential for ongoing technology development. Own your future!




TurboTides' optimization capabilities provides local and overall optimization within the TurboTides application.

Users can define the optimization process and target function; call other functions including Cycle, 1D, 2D, 3D geometry, grid generation, CFD, and FEA; and access input parameters and results from all steps in the design proces. 

With multi-disciplinary optimization, users can find the optimal design while considering all the requirements of the cycle, aerodynamic performance, and structural design.

Engineers can employ TurboTides' easy-to-use, built-in optimization capabilities at any step of the design process to optimize individual components and overall section or machine performance.  

Because of TurboTides' unified, easy-to-use interface, any turbomachinery designer can now undertake optimization in TurboTides without the deep, specialized knowledge of optimization methods and lengthy setup time that commercial optimization software packages usually demand.
