In-House Code Dev

Our laboratory specializes in the development of proprietary, high-performance simulation tools for fluid dynamics and related fields.

We:

Design in-house solvers in C, C++ and CUDA, enabling full control over numerical methods and optimization strategies.
Parallelized codes on large-scale clusters using OpenMPI, achieving scalable performance across hundreds of CPU cores.
Accelerate key kernels on GPUs, harnessing CUDA to deliver orders-of-magnitude speedups for compute-intensive workloads.

these capabilities let us push the frontier of computational science—rapidly prototyping new algorithms, validating them at scale, and deploying them on both CPU- and GPU-based supercomputing platforms.

Large-Eddy Simulation for VTOL Aircraft

CFD simulation of VTOL aircraft is highly demanding due to complex rotor–airframe interactions. We developed an in-house solver combining Actuator Line Method(ALM) and Immersed Boundary Method(IBM) to enable efficient, high-fidelity analysis with reduced computational cost.

Large-Eddy Simulation for Atmospheric Flows

Our in-house ABL wind solver is designed for wind turbine simulations, modeling the Atmospheric Boundary Layer (ABL) flow using Large Eddy Simulation (LES). Developed in C, C++, and CUDA, the solver models turbines using the Actuator Line Method, coupled with OpenFAST for aeroelastic simulation.

Direct Numerical Simulation for High Mach Number Flows

The in-house code has been developed to simulate high-order, high-resolution, and high-Mach flows. A compact scheme, known for its spectral-like resolution, is employed to achieve accurate flow representation. We take on large-scale challenges to unveil the underlying physics of complex phenomena in high-Mach flows.
