In this two-part paper, we present a collection of numerical methods combined into a single framework, which has the potential for a successful application to wind turbine rotor modeling and simulation. In Part 1 of this paper we focus on: 1. The basics of geometry modeling and analysis-suitable geometry construction for wind turbine rotors; 2. The fluid mechanics formulation and its suitability and accuracy for rotating turbulent flows; 3. The coupling of air flow and a rotating rigid body. In Part 2, we focus on the structural discretization for wind turbine blades and the details of the fluid–structure interaction computational …

In this article we present a high-performance computing framework for advanced flow simulation and its application to wind energy based on the residual-based variational multiscale (RBVMS) method and isogeometric analysis. The RBVMS formulation and its suitability and accuracy for turbulent flow in a moving domain are presented. Particular emphasis is placed on the parallel implementation of the methodology and its scalability. Two challenging flow cases were considered: the turbulent Taylor–Couette flow and the NREL 5 MW offshore baseline wind turbine rotor at full scale. In both cases, flow quantities of interest from the simulation results compare favorably with the reference …

The paper describes a Dual Operation concept and one example of its design. The amount of information the pilot must process, already high in current Air Traffic Management (ATM) operation, will increase dramatically in the envisioned future ATM environment. New pilot functions will require new levels of automation. Thus cockpit displays must be modified in order to facilitate the pilot's future tasks and to manage the increased information available. One approach to these challenges is to adaptively modify the displays depending on current pilot tasks and situation. Simply adding functionality to current day displays has the potential to reach an …
