Infiltration into a system of connected capillaries
    After sintering of a ceramic material we get a ceramic body, which in certain cases contains a network of connected channels. Into this network we would like to enter a second component by a process of pressureless infiltration.
    The classical model regarding infiltration into a capillary was developed by WASHBORN [1]. This model deals with only one capillary and is rather simplified. All the models regarding capillary infiltration into a porous material deals with one capillary or parallel capillaries that are not interconnected. Based on the classical model a more complicated model [2] was developed to describe the infiltration into two dissimilar capillaries that are connected to each other (Figure 1).
Figure 1. the capillaries system

A MATLAB program (5.3 version) demonstrates the infiltration rate into the system above. the user can define the dimensions of the system, and the physical properties. The output of the program is the infiltration rate with time
