Turbomachinery Simulation Analysis & Optimization Design Platform & Tools

Industry Challenges

Lack of Dedicated Modules

General-purpose software generally lacks dedicated modules for turbomachinery. Mesh generation and post-processing workflows are cumbersome and require heavy manual intervention

Weaknesses in Transient and Full-Annulus Simulation

Traditional simulation methods in the industry mainly rely on steady-state, single-passage rotational periodicity and multiple reference frame calculations. They cannot reproduce real transient rotational motion, nor capture non-uniform distribution effects across the full annulus

Severe Precision Degradation

Errors at stator-rotor interfaces accumulate step by step for multistage turbomachinery, and non-physical deviations may occur in precision for the final stage

Complex Physical Phenomena

Involving shock waves, stator-rotor interaction, boundary layer effects, heat transfer, flow-induced vibration and multiple other physical phenomena

Insufficient Support for Efficient Computation

This industry features typical system-level large-scale multi-scale scenarios with strong interaction between components. No corresponding efficient algorithms and hardware platforms are available to support large-scale computation

Solution Advantages

Full-Workflow Dedicated Modules

Dedicated turbomachinery modules cover the full workflow from preliminary 1D design → 3D detailed geometry creation → 3D CFD simulation and optimization, supporting fans, propfans, multistage axial/centrifugal compressors, turbines and more. Flexible mesh schemes are adopted for complex geometries such as damaged blades and disk cavities without geometric simplification, eliminating tedious manual work required by generic software.

Break Limitations of Traditional Steady-State Simulation

It adopts "iteration-free natural flow solving (direct simulation of physical time evolution) + Non-Conformal / Overset meshes" to handle rotor-stator interfaces, supporting full-annulus unsteady simulation of multi-stage rotating machinery.

Local reconstruction-based high-order algorithms (4D space-time polynomial design) allow independent adjustment of temporal/spatial resolution for local cells, eliminating traditional mesh synchronization and iterative redundancy. It enables Large Eddy Simulation (LES) with billions of solution points to reproduce real transient rotating processes and full-annulus non-uniform effects.

Break Limitations of Traditional Steady-State Simulation

Solve the Pain Point of Error Accumulation

Local reconstruction high-order algorithms preserve accuracy on non-conformal and overset meshes. When handling translating/rotating stator-rotor interfaces, fluid passes through interfaces with negligible dissipation. For instance, simulation of aero-engine stator-rotor interfaces produces errors that do not accumulate with computational scale.

Low-Cost Large-Scale Computation, Break Dependence on Supercomputers

Based on STE-KEP-FR space-time integrated algorithm and fully asynchronous parallel computing model, resolution can be improved by two orders of magnitude with identical computing resources. Large-scale computation can be powered by consumer-grade GPUs.
