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

Figure 12

Lagrangian variation of the charge density versus the normalized distance travelling from the initial point of a fluid particle while flowing along the streamline, numerically given at the three indicated values of 𝛼_𝜎 and at 𝑈=10⁻⁴ [m/s]. Initial points are (a) (𝑟,𝑧)=()=(𝑟_𝑐,0.02) and (b) (𝑟,𝑧)=()=(𝑟_𝑐,0.2).
