Abstract: A graphics processing unit (GPU)-based numerical simulation system and method for a helicopter flow field (FF). The GPU-based system includes a central processing unit (CPU) and a GPU. The CPU is configured to initialize a moving overset grid according to a preset configuration file and the mesh files of a to-be-simulated helicopter; determine face batch information according to mesh blocks in the moving overset grid; determine an overset interpolation relationship between the mesh blocks and an interpolation mapping index according to the mesh files at a current simulation moment; and perform FF information exchanging between the mesh blocks according to the overset interpolation relationship, the interpolation mapping index, and FF information of the mesh blocks, to obtain to-be-simulated helicopter FF information. The GPU computes the FF information of the mesh blocks in the motion nested mesh according to surface batch information by using a computational fluid dynamics (CFD) method.
