Good day, I hope you are doing well. <\/p>\n

I am trying to simulate particle deposition on wire screens using DPM in fluent. As we know, since fluent considers the particles as point particles, it doesn’t take into account the interception mechanism for particle capture on the wires which happens when the particles come within one particle radius from the wires(please refer to the following photo). I found this paper that has created a “virtual surface” around the wires to account for the interception. this line is from the paper:<\/p>\n

“In FLUENT, a “virtual surface” was created by building an <\/span>Interior Boundary <\/span>with the <\/span>Surface <\/span>function”.<\/span><\/p>\n

Later, to count the number of particles that had passed through that virtual surface, a sample report should be created for that surface (report>discrete phase>sample)<\/span><\/p>\n

Based on the approach that I took, I was able to create a surface that is an offset of my screen at the desired distance by using surface>create>transform>iso distance and then selecting my screen geometry. The problem is that it only creates a surface and not an “interior boundary” as stated above. Consequently, I can not get a discrete phase sample report on that surface (it won’t appear in the list). I believe that it should appear in the sample report list if I somehow get to define it as an interior boundary since I can see the interior-fluiddomain in the list (please refer to the last photo)<\/span><\/p>\n

Would you please help me with creating the interior boundary in the right way?<\/span><\/p>\n

Thanks in advance<\/span><\/p>\n
