The paper describes verification and validation of numerical model of fire and smoke development in a railway tunnel carried out in numerical code Fire Dynamic Simulator. To evaluate a correctness of numerical solution of the model with respect to the mathematical model, results are compared with solution executed in numerical code SmartFire. Influence of mesh size on results of gas temperature in vicinity to the fire source is studied. Validation of a level of agreement between the numerical model and a physical model is performed by comparison of calculated data with data measured during the fire test in road tunnel Valík located in the Czech Republic.
