Flow simulation directly driven from digital image data

Abstract

In the flow governing equations with embedded object boundaries (IB-NS), the flow solution around the object shape expressed by a level set function is defined without boundary conditions. This makes it possible to analyze the flow simulation of objects of arbitrary shapes represented by digital image data, etc., using only image processing technology. In this report, we introduce an example of the implementation of a flow simulation driven by image data representing two-dimensional and three-dimensional object shapes, using an open source image processing library.
