Research On Post-processing Techniques Of Propeller Design Integrated System

Propeller design integrated system breaks the traditional theoretical framework. Instead of simply accumulating various methods, the system is an organic integration based on self-development software. In order to study large quantities of result datas from the process of designing and forecasting, general software is needed to view the resulting datas, but it often fit poorly with products and not conducive to the promotion of products. Furthermore, it will increase the workload of analysts. Therefore, it's necessary to do some specialized researches on post-processing techniques of self-development software.Firstly, the essay expounded the theory of and development methods used in the systems, including geometric transformation of computer graphics and OpenGL.Secondly, this essay introduces the key technology of post-processing. In order to solve the problem of handling large data slow brought by cloud display algorithm, this paper proposed interpolation function based on OpenGL automatic cloud of ultra fast display of large-scale data algorithm,which improves the accuracy of contour display and display speed effectively. Considering Animation algorithm is prone to generate uncompleted key frame, a mechanism based on double buffer animation algorithm is proposed in this essay. Considering the disadvantages of a longer length of integration time for flow line display algorithm ,we propose a new algorithm, which has been studied and improved on the speed of interpolation, numerical integration and triangular grid point positioning.Improved results show that when the number of flow lines increase, the advantage to save flow line integral time of the improved algorithm is more obvious. To get rid of lower speed of finding the nodes and elements, a method based on the address hash chain search algorithm is proposed,which proved more efficient.Finally, key post-processing technique is introduced through examples in the propeller design practical application of integrated system, including the two-dimensional curves, color contour, vector, animation, propeller showed any cross-section, flow line results, Word automatically generated reports related applications . the study of propeller design integration system program could results in efficient, high-speed, high fidelity display computing results, which could fill the blank of the domestic theory of propeller design and performance-based software integration platform prediction method, and gradually narrow overseas gap of the propeller software applications. Besides, because this is an independent research and development product, which can make the research industrialization and commercialization.
