Role of diffusion and convection in drug transport. (a) cross-sectional profiles of Pe number at various axial positions in tumour interstitium, (b) quantitative comparison of normalized intracellular drug concentration at axial location z/L = 0.5 with and without convection under baseline pulse injection at t = 1.5 h (end of injection) and at t = 2 h (0.5 h after injection). Pulse characteristics of baseline pulse: pulse intensity S = 1, infusion time T = 1.5 h.
