Data belonging to the publication: A new coupling of a GPU-resident large-eddy simulation code with a multiphysics wind turbine simulation tool

This repository contains the processed data/figures belonging to the publication "A new coupling of a GPU-resident large-eddy simulation code with a multiphysics wind turbine simulation tool" by E. Taschner, M. Folkersma, L.A. Martínez-Tossas, R. Verzijlbergh and J.W. van Wingerden (2023). In this work, a new simulation environment is developed, which can be used to simulate wind turbines in the atmospheric boundary layer. The two main components are the large-eddy simulation code GRASP/ASPIRE and the turbine simulation tool OpenFAST. GRASP simulates the flow physics, whereas OpenFAST simulates the turbine dynamics (aerodynamics, structural dynamics, control system). The two codes are coupled via an actuator line model (ALM), which captures the footprint of individual turbine blades. The ALM implementation includes the filtered lifting line correction (FLLC). The ALM implementation is verified by simulating a laminar inflow case using the NREL 5 MW reference turbine, for which reference data from four other research LES-ALM codes are available. Furthermore, the performance of the FLLC is assessed, and its convergence behaviour and impact on runtime are studied.

本仓库收录了E. Taschner、M. Folkersma、L.A. Martínez-Tossas、R. Verzijlbergh及J.W. van Wingerden于2023年发表的论文《A new coupling of a GPU-resident large-eddy simulation code with a multiphysics wind turbine simulation tool》对应的经处理数据与可视化图表。本研究开发了一套可用于模拟大气边界层内风力发电机组的全新仿真环境，其主要包含两大组件：驻留GPU的大涡模拟（large-eddy simulation, LES）程序GRASP/ASPIRE，以及风力发电机组仿真工具OpenFAST。其中GRASP负责求解流动物理场，OpenFAST则用于模拟机组动力学特性，涵盖空气动力学、结构动力学与控制系统。两套程序通过执行器线模型（actuator line model, ALM）实现耦合，该模型可捕捉单根风力机叶片的流场影响区域，且本次实现的ALM集成了滤波升力线校正（filtered lifting line correction, FLLC）模块。为验证该ALM实现的正确性，本研究采用NREL 5兆瓦参考风力发电机组开展层流入流仿真实验，该场景已有其他4套主流LES-ALM仿真程序的公开参考数据可供比对。此外，本研究还评估了FLLC的性能表现，分析了其收敛特性与运行时长的影响。
