Modélisation du flot urinaire dans l'uretère chez l'Homme
The urine transport through the ureter is made with isolated pockets denoted “bolus”. We adopt some hypothesis, as axial symmetry, constancy of the bolus velocity and steadiness of the whole motion.
Taking into account the important terms, the analytical resolution of the equations leads to the determination of the field of velocities in the urine, in the wall and the bolus shape, depending on 5 parameters whose some suitable choice of the values permits to obtain solutions compatible with medical observations.
