The Influence of Chairs and Passengers on Air Velocity in Bus Passenger Compartment
Abstract The aim of the investigation is determination of compressing coefficient and air jet’s initial velocity under the condition, when bus passenger compartment is filled to a great extent with seats and passengers (sitting and standing). Air distribution experimental research was carried out in passenger compartment of different LAZ (Lviv Bus Plant) bus production models both at presence and absence of the passengers (in filled and empty bus passenger compartment). Air was supplied at the various flow rate through the different air distribution devices. Air exhaust was realized through the driver window. Air jet’s initial velocity of outlet from inflow hole and axial velocities in the bus passenger compartment service area has been experimentally determined. Measurement of the air jet’s velocity was made by thermal electrical anemometer Testo-405. Universal calculating equations of air jet’s velocities and determining factors have been expressed as dimensionless. Velocity of air jet’s outlet from inflow holes of different size and axial velocities in empty and filled bus passenger compartment of different production models have been measured. Dependence of compressing coefficient from three factors is determined and presented as a chart. Obtained chart has been approximated by equation.
