To examine whether the actual dimensions of human facial features are important to the development of a low-velocity inhalable particulate mass sampling criterion, this study evaluated the effect of facial feature dimensions (nose and lips) on estimates of aspiration efficiency of inhalable particles using computational fluid dynamics modeling over a range(More)
ii To: My parents Khalid and Sarah for their never ending support. My wife Alaa for her encouragement, patience, and believe in me. My children Khaled, Ahmad, and Sarah for bringing joy to my life. iii ACKNOWLEDGMENTS I would like to thank my advisor Dr. Thomas Peters for his support and guidance. I would also like to thank my committee members Dr. Patrick(More)
An understanding of how particles are inhaled into the human nose is important for developing samplers that measure biologically relevant estimates of exposure in the workplace. While previous computational mouth-breathing investigations of particle aspiration have been conducted in slow moving air, nose breathing still required exploration. Computational(More)
