Abstract :
The authors propose a numerical model to simulate the main physical processes occurring during catheter injection: blood dynamics is taken into account with the Navier-Stokes equations and the substance dispersion by the flowing blood with the advection diffusion equation. The model reproduces in vitro observations and allows one to evaluate some mixing properties of various catheter designs in different flow conditions
