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

Figure 9

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 four reference velocities indicated and at 𝛼_𝜎=10⁻³. Initial points are (a) (𝑟,𝑧)=(𝑟_𝑐,0.02) and (b) (𝑟,𝑧)=(𝑟_𝑐,0.2).
