INFLUENCE ANALYSIS OF THE DIFFERENT TYPES BUS BODY COMPOSITION ON THE CHARACTERISTICS OF THE AIR FLOWS FORMATION IN CONDITIONS OF FORCED CABIN CONVECTION

The paper proposes the influence analysis of five types city bus body layouts on air flows formation in cabin, generated by motor compartment fan under conditions forced convection. authors conducted three tests with different boundary finite element calculation module ANSYS Fluent: input velocity from fan, temperature and environment, internal external According to results simulated field tests, it was established that most effective is layout engine located horizontally rear overhang. Such a relatively expensive point view production, because requires installation opposite type "boxer" cases, which characterized higher cost, complexity maintenance less common contrast V-type combustion schemes. However, circulation occurs throughout cabin effectively this scheme, taking into account driver's other locations. Layouts central positioning (vertical horizontal) also deserve attention - they ensure symmetrical distribution front body, can be especially relevant cold period year.
