Detailed Description

template<class BasePhaseSystem>
class Foam::MomentumTransferPhaseSystem< BasePhaseSystem >

Class which models interfacial momentum transfer between a number of phases. Drag, virtual mass, lift, wall lubrication and turbulent dispersion are all modelled. The explicit contribution from the drag is omitted from the transfer matrices, as this forms part of the solution of the pressure equation.
