摘要:
我们基于符号距离函数,为演化光滑曲面和曲线周围的边界层正交坐标系提供了一个初等推导。我们超越了先前关于符号距离函数的工作,为这些坐标整理了有用的向量微积分恒等式。这些结果和提供的代码使得在广泛物理系统的边界层渐近推导中,能够一致地考虑几何效应。
英文摘要:
We provide an elementary derivation of an orthogonal coordinate system for boundary layers around evolving smooth surfaces and curves based on the signed-distance function. We go beyond previous works on the signed-distance function and collate useful vector calculus identities for these coordinates. These results and provided code enable consistent accounting of geometric effects in the derivation of boundary layer asymptotics for a wide range of physical systems.
