CAT - Complex analysis: techniques, applications and computations When a less viscous fluid is injected into a more viscous fluid in a Hele-Shaw, the interface between the fluids is unstable. This is the Saffman-Taylor instability which can give rise to a striking pattern formation at the interface. The usual model for this type of flow is a two-dimensional moving boundary problem which is amenable to complex variable methods, especially in the special case in which surface tension is ignored. For non-standard geometries progress can be made via numerical simulation, using a level set formulation for example. Some recent experimental, analytical and numerical studies of non-standard moving boundary problems in Hele-Shaw flow will be discussed. This is joint work with Liam Morrow, Tim Moroney and Michael Dallaston. This talk is part of the Isaac Newton Institute Seminar Series series. ## This talk is included in these lists:- All CMS events
