Witryna1. Introduction. Moving boundary problems are time-dependent problems describing the motion of a quantity such as fluid in a domain that is moving due to, e.g., the domain’s exterior boundary motion or the motion of an immersed structure within the fluid, or both. An immersed structure within the fluid defines an interior fluid domain ...
