DESCRIPTION:Understanding the interaction of liquids with solids (wetting)
  and other liquid bodies (coalescence) holds the key to optimizing a whole
  host of technological processes\, including a number of emerging microflu
 idic devices such as 3D-printers.  Accurate experimental observation of th
 ese phenomena is complex due to the small spatio-temporal scales or intere
 st and\, consequently\, mathematical modelling and computational simulatio
 n become key tools with which to probe such flows.\n\nDynamic wetting and 
 coalescence are both so-called `singular' capillary flows\, in which class
 ical modelling approaches lead to paradoxical conclusions.  In the case of
  wetting this is the well-known 'moving contact-line problem'.  In this ta
 lk\, I will describe the various models proposed for this class of flows a
 nd\, by comparing the predictions of these theories to experiments\, expla
 in why there is still an intensive debate in this field. Finally\, I will 
 outline some recent work on wetting where the dynamics of the displaced ga
 s plays a key role in determining the critical point at which flow transit
 ions occur.
