摘要
We present an improved lattice Boltzmann model of multi-component flow which permits practical, hydrodynamic modelling of multiple immiscible fluids. The model is robust and significantly reduces-the interface anisotropy and micro-currents, which are artefacts observed in many schemes. Our new scheme is used on a particular regime of blood flow: that of the veinule mesoscale, where it is necessary to resolve significant numbers of deformable, interacting cells, which we model as incompressible liquid drops. We demonstrate the model's ability to recover the complex flow phenomena typical of the veinule scale.
