Exposures to airborne particles and toxic gases generated by welding fabrication activities
will potentially lead to various diseases. Accurate information on the transport and
deposition of such aerosols in the respiratory system is critically needed for precise health
risk assessments. To address the data demand mentioned above, a multiscale
computational fluid-particle dynamics (CFPD) model was developed in this study.
Specifically, a virtual fabrication shop was integrated with a virtual human in the numerical …
