Visualization for computational fluid dynamics and the comparison with experiments
Abstract
Three aspects of the postprocess of computational fluid dynamics (CFD) and their requirements are described. One aspect is visualizing flow fields as one method of processing numerous data. Various ways of displaying various flow functions and user-friendly man-machine interface is emphasized in this aspect. The second aspect is illuminating the physics of the computed flow fields. Streamline tracing is an example for this purpose. The third aspect is validating computer simulations. Emphasis is made on the method to simulate the process of experimental visualizations for computed results in order to compare the results with pictures obtained in experiments. It is concluded that the real postprocess of the CFD is not only to visualize computed flow fields but also to 'cook' the computed flow field to illuminate the flow characteristics, and generating nice and beautiful pictures without flow physics is out of the CFD research.
