I have developed an alternative numerical approach to study mass transfer from a stationary core-shell reservoir under channel flow conditions. I use the lattice Boltzmann method to compute both the solvent fluid flow and the diffusion and advection of the solute. I have investigated the impact of the flow by reporting mass transfer quantities such as the instantaneous solute concentration and the local Sherwood number at the surface of the reservoir. The flow is found to enhance the release of the encapsulated material, but it prevents the released material from reaching the channel walls.
我开发了一种替代的数值方法来研究在通道流条件下从固定核壳储液器中进行的传质。我使用晶格玻尔兹曼方法来计算溶剂流体流动以及溶质的扩散和对流。我通过报告传质量，如储液器表面的瞬时溶质浓度和局部舍伍德数，来研究流动的影响。发现流动增强了被包裹材料的释放，但阻止了释放的材料到达通道壁。
