An experimental study on particle deposition above near-wall heat source
To investigate the effect of near-wall heat sources on the particle deposition, an experiment on particle dimensionless concentrations and size distributions above a near-wall heat source and in the indoor environment is performed. The suspended particles above the near-wall heat source and in the a...

| description | To investigate the effect of near-wall heat sources on the particle deposition, an experiment on particle dimensionless concentrations and size distributions above a near-wall heat source and in the indoor environment is performed. The suspended particles above the near-wall heat source and in the adjacent indoor air are measured and compared. Then the particles are collected under twenty-five different cases by using a Grimm 31-Channel Portable Aerosol Spectrometer. The results reveal that the particles above the near-wall heat source have larger deposition rate than that in the adjacent indoor air. Particles with 0.75 μm–11.25 μm dimension stay more in the air above the heat source than in the adjacent indoor air. We also found that the particle decay rate loss coefficient increases as the heat source surface temperature increases, and it reduces as the gap between the heat source and the wall increases.
•The effects of a near-wall heat source on particle deposition are presented.•The suspended particles above heat source and in the adjacent indoor air are measured.•The effects of heat source on particle decay rate loss coefficient are discussed. |
