《Influence of feature size of micro-scale channel on ink flow characteristics》
Zhang[6]obtained an ink flow model with feature size of 0.02mm,which was based on liquid-solid coupling relationship.In the model,the wall internal diameter is 30mm,the initial ink thickness at inlet and outlet is set to 0.08mm,and the center distance of two rollers is 29.95mm.With the center distance of two rollers and the wall diameter remaining unchanged,the ink flow models under different feature sizes are obtained by enlarging or decreasing in multiples.The shape of the model is shown in Fig.2,and the specific dimensions of each model are illustrated in Table 1.As seen from Fig.2(a),the ink layer is attached to the surface of two ink rollers,and the micro-scale channel is formed by the extrusion of two ink rollers.This paper builds ink flow models as Fig.2(b).To a great extent,mesh quality affects the speed and accuracy of calculation.Therefore,in order to get grids of good quality,this paper uses a specialized fluid mesh generation software ICEM CFD to mesh each ink flow model.And hexahedral structured mesh is obtained by block partitioning.
