DEVELOPMENT OF 3-DIMENSIONAL BLADE DESIGN SYSTEM USING VIRTUAL REALITY TECHNIQUE
要約
Conventional blade rows in turbo-machinery have been designed 2-dimensionally. However, the enhanced request to improve the performance makes 3-dimensional design inevitable. In the present study, we propose a design system for 3-dimensional blade, applying virtual reality techniques. Using a head mount display and a pen-type 3-D mouse, this system enables a designer to visualize the flow field and to modify the blade configuration. Once the shape of a blade is changed, the flow around the modified blade is calculated and the results are displayed on the head mount display, iteratively. IRIS Explorer is basically used for the flow visualization. The flow is assumed to be 3-dimensional, inviscid, and compressible because of the light computational load. This system would be effective in knowing the trend of aerodynamic performance with deforming a blade configuration, and is also promising for students and/or beginners in learning 3-dimensional flow fields around a 3-dimensional blade.
