Abstract Evaporation of saline droplets significantly impacts industrial processes such as water and gas treatment. Simulations, with advantages in describing temperature, concentration, velocity distribution inside the droplet, receive increasing attentions. This paper summarized research on numerical simulations droplet evaporation at micro‐, meso‐, macroscales, emphasizing or multicomponent droplets. Accurate description physics phase interfaces within proves to be critical for modeling. While recent studies have investigated interface motion temperature distribution, coupling effect internal concentration flow is still rarely considered. Among methods, lattice Boltzmann method suitable scale due its ability handle non‐continuum behavior. Bridging multiscale models remains a challenge, particularly Marangoni capillary flows. Experimental approaches effects external physical fields (electric, magnetic, convection, laser) substrate properties were also reviewed. Visualizing under various conditions can validate macroscopic models, while experiments different substrates molecular simulations, primarily affect by affecting bottom. comprehensively reviewed evaporation, analyzed advantages, limitations, development directions methods.

Natural ventilation via open windows is a common practice widely applied to dilute aerosols in dental offices for all year around China, which, however, would modifies air distribution and leads extra energy consumption cooling heating. This study intends evaluate aerosol removal efficiency multi-chair office with both mechanical (MV) natural (NV), namely, mixed-mode (MMV). It numerically investigates the effect of mode environmental condition on indoor fallow time (FT) duration, as well consumption. The results show that introducing fresh such mechanically ventilated space enhanced airflow mixing particle dispersion. Compared six changes per hour (ACH) MV mode, MMV less than 4 ACH NV does not ensure reduction suspended count indoors. When rate reaches 6 ACH, compartments an average 64.6% counts. However, 3.5 times higher during heating seasons 2.2 compared mode. recommended FT 18–21 min between appointments, 4–6 has required 14–16 min. intended provide references clinic managers balance quality improvements consumption, thereby achieving sustainable environment optimizing operational costs offices.
