Extensional flow of nematic liquid crystal under electric field gradient

Cummings, L. J.; Myers, T.G.; Low, J. (2011)

Systematic asymptotic methods are used to formulate a model for the extensional flow of a thin sheet of nematic liquid crystal. With no external body forces applied, the model is found to be equivalent to the so-called ...

Modelling the cooling of concrete by piped water

Myers, T.G.; Fowkes, N.D.; Ballim, Y. (2010-01)

Piped water is used to remove hydration heat from concrete blocks during construction. In this paper we develop an approximate model for this process. The problem reduces to solving a one-dimensional heat equation in the ...

Optimal exponent heat balance and refined integral methods applied to Stefan problems

Myers, T.G. (2010-01)

When using a polynomial approximating function the most contentious aspect of the Heat Balance Integral Method is the choice of power of the highest order term. In this paper we employ a method recently developed for thermal ...
