Numerical Study on the Charge Transport in a Space between Concentric Circular Cylinders

Figure 6

Passage of the charge transmission from the inner cylindrical wall at 𝑟=𝑟₁ to the outer cylindrical wall at 𝑟=𝑟₂. Also shown are the thickness of the passage at 𝑧=ℎ/2 on the inner wall, 𝛿_𝐿𝑐, and that at 𝑟=𝑟_𝑐 on the top wall, 𝛿_𝑇𝑐.
