“…Larger concave extent and inclined angle difference both prompt more transformation to the essential flow field structure. As discussed in Section 1, the effect of inclined angle 20 and morphology 23 of baffle walls is noteworthy and can be applied to enhance device capacity. The findings in Sections 4.2 and 4.3 are consistent to related work.…”

“…Many research studies have employed baffle to improve flow property and topology in channels, for example, Wang et al 20 designed a baffle to regulate the vortex in the deduster channel and found out that the low velocity zone was significantly improved when the inclined angle of the baffle was 90 • , which has enhanced the capacity of particle trapping. Baffle can also be utilized to optimize mass transfer ability, such as in the work reported by Wang et al, 21 where the oxygen transporting level brought by the new design with baffle structure had successfully out-performed the original orbitally shaken bioreactors.…”

Microfluidics technology is promising in developing microparticle manipulation technology due to its nondestructive control and notable adaptability. The manipulation of microparticle based on swirling stagnation point is one of the feasible microfluidics biotechnologies. Aiming to improve the regulation and control of microparticle, baffle wall is introduced into the 2‐microchannel flow field. The theory of wall attachment jet is employed to elucidate the effect of baffle wall. Subsequently, finite volume method simulation is conducted by modeling the swirling flow region (SFR), and the swirling strength is calculated to characterize the SFR's particle‐capturing ability. Experimental validation of the modeling and simulation methods is performed using a printed microfluidic chip, which has demonstrated exceptional reliability. Simulation results show that the baffle wall makes considerable influence on the SFR. Strikingly, a global range adjustment of stagnation point is realized when the baffle wall is configured with a convex shape, which has remarkably outperformed our previous work, where the stagnation point could only move within half range of the field. This work significantly contributes to advanced flow field structure and provides insight into better regulation of stagnation point as well as microparticles. These findings have potential applications in the analysis of the effect of bio/chemical substances on single cell.

“…Dust usually contains particles of various sizes and shapes, which causes difficulties in its description and modeling [10]. In addition, dust generation and movement processes in manufacturing systems are often dynamically heterogeneous, which makes the accurate PSD assessment difficult [11][12][13][14][15].…”

Particle size distribution is an important parameter for dust quality and properties assessment as well as a factor to estimate the air dustiness influence on humans and the choice of an appropriate dedusting means. The academic literature analysis shows that, unlike technological dust, there is practically no information available about theoretical models of metal machining dust size distribution. In addition, researchers rarely use finite functions, although an appropriate particle size distribution determination is crucial for dedusting ventilation systems designed for machine tools. The article examines the metal machining dust particle size distribution description using finite and infinite functions, and discusses the features and advantages of their application. As a result, it is concluded that infinite functions are good at describing dust with a high extremity of outliers. On the contrary, finite functions appropriately describe dust with low tailedness, the measure of which is the kurtosis. It should be noted that the obtained results are related to the dust analysis methods, including sieve analysis when selecting a sieve size range.
