Abstract The ventilation flow in a car cabin has been experimentally investigated. study carried out commercially available, by testing one mode (panel-vent mode) at fan strength (level 3 of the 4 available) with fresh air intake (without any re-circulation). velocity exit vents measured using 5-hole pressure probe. fields inside have particle image velocimetry (PIV) three longitudinal sections...

It has frequently been claimed that cycling in heavy traffic is unhealthy, more so than driving a car. To test this hypothesis, teams of two cyclists and two car drivers in two cars were equipped with personal air samplers while driving for 4 h on 2 different days in the morning traffic of Copenhagen. The air sample charcoal tubes were analysed for their benzene, toluene, ethylbenzene and xylen...

The aim of this paper is double : propose a methodology for a probabilistic prognosis, and examine how the prognosis result impacts the maintenance process. First, the prognosis problem is mathematically defined: it consists in computing the distribution of the Remaining Useful Life (RUL) of the system conditionally to on-line available information. Considering on-line information allows to pro...

Prediction of particle transport in enclosed environment is crucial to the welfare of its occupants. The prediction requires not only a reliable particle model but also an accurate flow model. This paper introduces two categories of flow models – Reynolds Averaged Navier-Stokes equation modeling (RANS modeling) and Large Eddy Simulation (LES); as well as two popular particle models – Lagrangian...

The smoke layer height in the ship engine room under forced ventilation has been experimental and theoretical investigated this work. A series of test were carried out a scaled cabin platform to obtain influence air supply volume inlet on burning parameters, including mass loss rate, temperature, etc. research results show that conditions, fire source rate increases exponentially, also graduall...
