经典的单相Stefan问题描述了均匀介质中经历相变的温度分布,例如冰融化成水。这是通过求解与时间相关的区域上的热方程来实现的,该区域的边界由温度沿演化的和先验未知的自由边界的法向导数来传输。我们使用一种新的混合方法,结合了能量估计、衰变估计和Hopf型不等式,建立了近球形几何形状和小温度下的全局时间稳定性结果。
The classical one‐phase Stefan problem describes the temperature distribution in a homogeneous medium undergoing a phase transition, such as ice melting to water. This is accomplished by solving the heat equation on a time‐dependent domain whose boundary is transported by the normal derivative of the temperature along the evolving and a priori unknown free boundary. We establish a global‐in‐time stability result for nearly spherical geometries and small temperatures, using a novel hybrid methodology, which combines energy estimates, decay estimates, and Hopf‐type inequalities.© 2015 Wiley Periodicals, Inc.
