基于多核并行计算的无人机CFD数值模拟
CFD numerical simulation of unmanned aerial vehicle based on multi-core parallel computation
摘要
Abstract
With the computer system developing towards multi-processor and multi-core architecture,a CFD(Computa-tional Fluid Dynamics)numerical simulation method with multi-core CPU has been proposed to solve large-scale aeronautical engineering problems accurately.The serial and parallel solution program is validated using a tested wing. The numerical method based on N-S(Navier-Stokes)equations proves its effective and the parallel efficiency as well as the execute time and speed-up ratio is discussed.An efficient parallel computation method is developed to calculate the longitude aerodynamics for Unmanned Aerial Vehicle(UAV). Script record of FLUENT tool is applied for switching and saving processes automatically.The advantage of parallel method as well as the modular working principle has been introduced.关键词
