“…The temperature of the model's skin was 6‐10°C lower than that of human skin. The consequent variation in thermophoresis on micron‐sized particles is negligible . Nevertheless, when in a state of thermal comfort, the human body dissipates 30‐35% of its metabolic heat via convection.…”

“…The consequent variation in thermophoresis on micron-sized particles is negligible. 41 Nevertheless, when in a state of thermal comfort, the human body dissipates 30-35% of its metabolic heat via convection. The human convective boundary layer (ie, the body plume) interacts with the surrounding airflows and modifies their movement around the human microenvironment.…”

Exposure to particulate contaminants can cause serious adverse health effects. Deposition on the facial mucosa is an important path of exposure, but it is difficult to conduct direct dose measurement on real human subjects. In this study, we propose an in vitro method to assess the administered doses of micron‐sized particles on the eyes and lips in which computed tomographic scanning and three‐dimensional printing were used to create a model that includes a face, oropharynx, trachea, the first five generations of bronchi, and lung volume. This realistic model of a face and airway was exposed to monodispersed fluorescent particles released from an incoming jet. The administered dose of particles deposited upon the eyes and lips, as quantified by fluorescence intensity, was determined via a standard wiping protocol. The results show that, in this scenario, the administered doses normalized by source were 2.15%, 1.02%, 0.88%, 2.13%, and 1.55% for 0.6‐, 1.0‐, 2.0‐, 3.0‐, and 5.0‐µm particles, respectively. The administered dose of large particles on the mucosa within a given exposure time has great significance. Moreover, the lips suffer a much greater risk of exposure than the eyes and account for more than 80% of total facial mucosa deposition. Our study provides a fast and economical method to assess the administered dose on the facial mucosa on an individual basis.

“…22 Additionally, features like roughness and temperature can affect the COR. The studies by Li's team systematically delved into these correlations, unveiling that an increase in temperature 23 and surface roughness 24 negatively impact COR. They further develop the model to predict COR at different impact angles.…”

“…It remains an ongoing debate in the literature how to parametrize and measure cohesive forces accurately [70,71,72]. As summarized in [41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68] of common natural particulates and dust constituents. Upper and lower bounds correspond to the 10-th and 90-th percentile when distributions are given.…”

Particle deposition in fully-developed turbulent pipe flow is quantified taking into account uncertainty in electric charge, van der Waals strength, and temperature effects. A framework is presented for obtaining variance-based sensitivity in multiphase flow systems via a multi-fidelity Monte Carlo approach that optimally manages model evaluations for a given computational budget. The approach combines a high-fidelity model based on direct numerical simulation and a lower-order model based on a one-dimensional Eulerian description of the two-phase flow. Significant speedup is obtained compared to classical Monte Carlo estimation. Deposition is found to be most sensitive to electrostatic interactions and exhibits largest uncertainty for mid-sized (i.e., moderate Stokes number) particles.
