Abstract

Nowadays, the thermal comfort in the means of transport is an important field of research, which have a positive impact on the health of the passengers and the driver. The latest research, results and methods, to determining the comfort in means of transport are presented in the first part of the paper. The thermal comfort study is carried out on an existing bus geometry. The bus geometry is modelled in SolidWorks using blueprints available on the web. The simulation is done for three cases: the first case where the ventilation system is open at maximum capacity, the second case where the ventilation system works at maximum capacity whit the air deflectors mounted for a better distribution of the air and the last case when the bus velocity is 14m/s whit two rear windows opened. The results of the first simulations are analysed and a location of deflectors is proposed for an optimal distribution of air inside the bus. In the last part of the paper we compare the obtained results, highlighting the conclusions of this study.a
