Celleaksenvinklene

Celleaksenvinklene, also known as cell leak angles, refers to a theoretical concept in certain computational fluid dynamics simulations or physical models. It describes the angular deviation or deflection of a "leakage" or flow from a cell boundary within a discretized grid system. In numerical simulations, continuous physical phenomena are represented by discrete cells or elements. When a fluid or other quantity is modeled as moving, it might "leak" or pass from one cell to another. Celleaksenvinklene quantifies the directionality of this transfer, particularly when it doesn't occur perfectly perpendicularly to the cell face.

This concept is relevant in scenarios where the accuracy of inter-cell communication is crucial. For instance, in porous media flow simulations or when modeling transport phenomena across interfaces, the precise angle of fluid movement can significantly impact the overall results. If the leakage is not aligned with the primary grid axes, a simple orthogonal flux calculation might introduce errors. Understanding and accounting for these angles can lead to more robust and accurate simulations, especially in complex geometries or when dealing with anisotropic flow properties. The term itself is not a widely established standard in general fluid dynamics literature but may appear in specific research contexts or specialized software.
