Eulerian-Lagrangian model for traffic dynamics and its impact on operational ventilation of road tunnel
Original language description
The contribution deals with a computational Eulerian-Lagrangian model that simulates movement of cars inside a road tunnel and its impact on operational ventilation. The model simulates moving cars as a discrete objects that "fly" through the tunnel. Theobjects are treated with Lagrangian momentum equation and their velocity is solved along their trajectories that are determined by the shape of the roadway. The ambient air is solved with a commercial CFD code StarCD. Due to drag force, the cars virtuallly change their velocity, but this latter is continuously re-set to its original value. Momentum equation for continuous phase contains an additional source term that results from the net efflux of momentum of cars when they enter and leave a particularcontrol volume of the solution domain. The model [1] can simulate cars moving with different speed and traffic rate in individual traffic lanes. As a result we obtain flow rate generated by moving vehicles as a function of traffic speed
