Keywords: experimental data, numerical simulation, thermal comfort, moving sun
The evaluation and improvement of passengers comfort degree is a basic task of vehicle manufacturers. To achieve a high thermal comfort, most manufacturers provide a system for their cars to ensure ventilation, heating and cooling air in the cabin.
The purpose of this paper is to evaluate the temperature and humidity inside a moving car on the highway Pitesti - Bucharest. The software used for the numerical simulation is Theseus FE and the results obtained are compared with the values obtained for experimental tests.
Computer simulation was performed for a medium class car, moving at a speed of 120km/h on the highway Bucharest - Pitesti, at two time scales, while retaining the same sense of movement, i.e. from Pitesti to Bucharest. Values for exterior temperature and humidity, as well as for the sun position are dated July 24, 2009. Since Pitesti - Bucharest highway length is about 120km the numerical simulation time was considered 3600s.
