Visualization of the distribution of a physical quantity on a deformed interfacial surface

The study addresses the problem of visualizing the distribution of a physical quantity (e.g., pressure or velocity) on a deformed interfacial surface arising in fast physical and engineering processes, such as bubbling, cavitation, spraying, and heterogeneous reactions. A specific feature of such processes is that their efficiency depends not only on the values of the quantity but also on the geometry of the interfacial boundary itself. This paper proposes an approach to developing an information system that provides a three-dimensional visualization of an interfacial surface and captures the temporal dynamics of the distribution of the physical quantity. The surface can be specified either analytically, via a parametric function, or in tabulated (experimental) form. A modular system architecture has been implemented using a developed binary file format: a data generator generates animated surfaces, and a visualizer based on OpenGL renders them as a sequence of frames, with a color legend defining the values of the physical quantity. The resulting system was tested on statically and dynamically specified surfaces. Visualization was performed for both external data, including the interaction of aerosol particles calculated using an external solver based on the boundary element method, and for models in which an analytical function, such as capillary waves, specifies the surface profile. The stability of system operation and the correctness of interpretation of physical quantity distributions were demonstrated. The developed system is universal, features an extensible architecture, and can be used to visualize computational or experimental data in problems of multiphase flow mechanics, thermophysics, and chemical engineering.
