Heavy-element ion line emissions are simulated with a numerical code using two adjustable, radius-independent, parameters in the flux density expression: an anomalous diffusion coefficient DA and an inward convective velocity VA. Previously reported results on the laser blow-off injection of V, Cr, and Ni are, thus, interpreted. The quasi-stationary phase of Ohmically heated high-density (ne(0) ≈ 1.5 × 1014 cm−3) discharges is also simulated, thus allowing the plasma impurity content and the radiated power to be calculated. The necessary numerical values of DA and VA are in the range of 2000–4000 cm2·s−1 and 400–800 cm·s−1, respectively.
