A process of detailed CFD and structural numerical simulations of the 1.5 MW horizontal axis wind turbine (HAWT) blade is present. The main goal is to help advance the use of computer-aided simulation methods in the field of design and development of HAWT-blades. After an in-depth study of the aerodynamic configuration and materials of the blade, 3-D mapping software is utilized to reconstruct ...

A benchmark turbulent Backward Facing Step (BFS) airflow was studied in detail through a program of tightly coupled experimental and CFD analysis. The theoretical and experimental approaches were developed simultaneously in a “building block” approach and the results used to verify each “block”. Information from both CFD and experiment was used to develop confidence in the accuracy of each tech...

Multiphase catalytic reactions are prominent in chemical engineering; however it is difficult to achieve efficient reactions. Computational fluid dynamics (CFD) software simulates fluid flow so interactions between phases may be analyzed and improved. This project included use of CFD to simulate an experiment on multiphase flow to compare results on flow regime and pressure drop. Results includ...

Computational researchers typically work by accessing a compute resource miles from their desk. Similarly, their simulation output or other data is stored in remote terabyte data servers. VisBench is a component-based system for visualizing and analyzing this remote data. A time-varying CFD simulation of heat exchange over a louvered n provides sample data to demonstrate a workbench-oriented ve...

The Solar powered unmanned aircraft have a high-aspect-ratio wings because SPUAV must satisfy the requirement of long endurance and high lift-drag ratio. Therefore, the structure of SPUAV‘s wings are structurally very flexible. The very high flexible wing might have large deformation and many aeroelastic problems. In this paper have a static/dynamic aeroelastic analysis through CFD-CSD coupled ...
