Resumo

The hydrodynamics of a tee is investigated in the problem of determining the optimal vascular bypass angle during treatment. Four possible bypass angles corresponding to the most commonly used real configurations are considered: π/6, π/4, π/3, and π/2. The problem is solved numerically using the ANSYS code. The condition of minimum integral of the viscous dissipation energy is used as an optimality criterion. It is shown that a bypass angle of π/3 is optimal and π/4 is the least favorable angle.
