    Transport and Deposition of Wear Particles in Computer Disk Drives (1992)
    Weinheim : Wiley-Blackwell
    Particle and Particle Systems Characterization 9 (1992), S. 31-39 
    Details
    ISSN: 0934-0866

    Notizen: To understand the roles that wear particles play in disk crashes, analytical and numerical approaches have been used to study three dimensional fluid flow and wear particle transport and deposition in computer disk drives. The study shows that wear particles are flying very close to the disk surface. They can deposit on the disk surface and cause damage to disk drives. Cooling air flow through the disk hub of corotating disks has been found to play important roles in removing wear particles from disk drives. Parametric study has shown that the optimum cooling air flow rate is 12 slpm for 8″ disk with the Reynolds number of 150,000.

    A Field Study of Three Collocated Ambient PM10 Samplers (1995)
    Weinheim : Wiley-Blackwell
    Particle and Particle Systems Characterization 12 (1995), S. 10-15 
    Details
    ISSN: 0934-0866

    Notizen: The performances of three ambient PM10 samplers were studied at three monitoring stations in Taiwan. It was found that differences in the daily measured PM10 concentrations of the SA 1200 and Wedding high-volume samplers are now within ± 10% since the former now has a closer cut-point to the latter than in the earlier SA 321 A model. The Wedding beta gauge automatic sampler was found to be applieable in rainy and humid weather conditions in Taiwan. Its daily PM10 concentrations are typically within ± 10% of those of the Wedding highvolume sampler. The particle loading effect of Wedding highvolume and beta gauge samplers was found to be important. To avoid sampling errors due to the loading effect with ambient PM10 samplers, they must be cleaned regularly at an interval depending on the ambient particulate level.
