Industry Challenges

Difficult High-precision Modeling

Fuel assemblies in the primary loop of reactors feature intricate structures. Conventional software relies on porous media models to simplify geometry, making it hard to accurately capture fine details such as flow-induced vibration and noise

Conflict Between Computational Cost & Efficiency

Full-scale physical experiments incur enormous costs and high risks. Traditional iterative algorithms see non-linear growth in computing demand with simulation scale, resulting in long simulation cycles for complex systems

Poor Stability of Multi-physics Coupling

Under high-temperature and high-pressure operating conditions, multi-physics coupling of flow field, heat transfer and structure is vulnerable to parameter interference, leading to low matching accuracy between simulation and experimental data

Solution Overview

Equipped with core technologies including LES transient simulation, native GPU support and STE-KEP-FR spatiotemporal integrated algorithm, it delivers advantages such as high-resolution unsteady simulation, low-cost high-efficiency computation, stable multi-physics coupling, ultra-large-scale system-level simulation and in-depth integration with digital twins. We provide high-precision, low-cost, full-scenario simulation solutions for the nuclear energy sector to help optimize nuclear power safety design, boost equipment operation & maintenance efficiency, and promote the upgrade of nuclear industry from "simplified estimation" to "accurate evaluation".

Solution Advantages

Flexible Geometry Resolution & Multi-physics Coupling

The immersed boundary method is adopted to precisely capture geometric details of grids. It supports flow-thermal-structure coupled simulation (e.g. thermal-hydraulic analysis of fuel assemblies) and enhances the stability of multi-physics coupling.

High-resolution Unsteady Simulation

Based on the STE-KEP-FR spatiotemporal integrated algorithm, complex flow fields can be simulated with high precision without geometry simplification. Free from parameter dependency of porous media models, it accurately calculates key indicators including flow-induced vibration and noise.

Low-cost & High-efficiency Computing

Natively supports parallel computing on consumer-grade GPUs. The fully asynchronous model achieves 10–100x acceleration, cutting simulation time cost of complex systems by 10 times and reducing hardware cost by 2–3 orders of magnitude.
