This study intends to investigate indoor air environment via the flow fields, temperature fields and air contaminant (carbon monoxide) distributions in the conventional residential kitchens, and look for effective methods to solve those problems through natural ventilation techniques.
The investigation is related to a recent experimental study that revealed that the carbon-monoxide distribution substantially differs in the near-wall region when compared to an undisturbed flame.
This revised model successfully captures the important features in the experimental TOF distributions, including: (i) the impulsively scattered and thermally desorbed components in the oxygen (O) TOF distributions, and (ii) the relatively slow long-tail components in the carbon monoxide (CO TOFF distributions.
The experimental works involved the measurements of the axial distribution of carbon monoxide concentration, whereas the theoretical analyses were on the use of an Multi-Scale Mass Transfer (MSMT) model with considering effects of clusters on gas-solid transport phenomena in the CFB.
Carbon monoxide (CO) relative concentration and velocity distribution from a vehicular exhaust plume in the near-wake region is investigated for low and high idling driving conditions under different ambient wind speeds.
This interpretation is supported by the distribution of the carbon monoxide, which is also concentrated in the vicinity of ±60° latitudes.

The shape and the position of the reaction zone are experimentally identified from the distribution of temperature and carbon monoxide in a particular symmetry plane.
Techniques have been developed using O labelled water and carbon monoxide to quantify regional perfusion, fractional volume of distribution of water (VD) and blood volume (BV) within tissues.
The results demonstrate the strong influence of the coal feed and the solids return on the spatial distributions of volatiles, char, oxygen and carbon monoxide.
These measurements included PM, PM size distribution, PM composition (carbon, ions, elements), NOx, carbon monoxide, speciated/total volatile hydrocarbons, and several classes of semi-volatile organic compounds.
