Summary\uff1a<\/span><\/p>\n

This article is part of the series exploring the secrets of e-cigarette flavor, focusing on \"Aerosol Edition.\" It discusses the factors that form the flavor of electronic cigarettes. The key to flavor lies in the formation, evolution, and transport of aerosols, which include processes such as nucleation, condensation, evaporation, and coagulation. The article also explains that electronic cigarette aerosols are mainly composed of tiny particles and liquid particles. This content helps to deepen the understanding of the mechanism behind the formation of e-cigarette flavors.<\/p>\n

With the rapid development of the new atomization industry, users' expectations for electronic cigarettes have gone beyond the simple \"smoke-producing\" stage. Today's users seek high-fidelity, satisfying, and smooth vaping experiences from electronic cigarette products. Therefore, the flavor has become the ultimate standard for judging the quality of electronic cigarettes. But what factors influence the flavor?<\/p>\n

This series will start from the mechanism, guiding you through the various factors that affect the formation of electronic cigarette flavor, to deepen your understanding of the flavor formation mechanism.<\/p>\n

Topic 1: Formation, Evolution, and Transport of Aerosols<\/p>\n

First, let's introduce a concept. An aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gaseous medium. The smoke from traditional cigarettes is made up of solid particles produced by the combustion of tobacco, while the vapor from electronic cigarettes is made up of liquid particles formed by the evaporation and condensation of the e-liquid. Both are suspended in the air medium to form aerosols, but their formation mechanisms and research methods are different.<\/p>\n

(1) Formation and Evolution of Aerosols<\/p>\n

Nucleation: In a mixture composed only of vapor, one or more chemical components may be in a supersaturated state, meaning that the partial pressure is greater than the equilibrium vapor pressure of the mixture. Energetically, this is conducive to the recombination of vapor molecules into a liquid phase. If the degree of supersaturation is high enough, it can overcome the energy barrier associated with the formation of a liquid droplet surface, leading to droplet nucleation.<\/p>\n

Condensation and Evaporation: Vapor molecules are more likely to change phase and condense onto existing surfaces. This process is driven by the saturation of the vapor and the mobility of the vapor molecules relative to the mixture. If the vapor becomes unsaturated, aerosol droplets may begin to evaporate and disappear.<\/p>\n

Coagulation and Fragmentation: In dense aerosols, particles may collide with each other. With these collision events, two particles may combine; they coagulate. Conversely, there is also a probability that particles will be scattered into multiple particles, i.e., fragmentation.<\/p>\n

(https:\/\/www.intervals.science\/resources\/aerosolved<\/a>)<\/p>\n

(2) Transport of Aerosols<\/p>\n

Drift: Particles have different properties from the carrier gas, such as density or viscosity, which may cause the particle phase to deviate from the movement of the carrier gas. This movement can be caused by inertia, for example, when droplets carry too much momentum to quickly adapt to local accelerations experienced by the carrier gas.<\/p>\n

Diffusion: When particles are small enough, this Brownian motion leads to the diffusion of droplets. From a macroscopic perspective, this diffusion is like \"regular\" molecular diffusion, making the aerosol appear more dispersed quickly.<\/p>\n

Deposition: The speed of the carrier gas at this surface is zero, which means that no gas molecules can pass through the surface. If aerosol particles precisely follow the flow lines of the carrier gas, their movement will also stagnate at the surface, thus preventing deposition. However, aerosol drift and diffusion may cause net transport of particles that deviate from the carrier flow lines. Therefore, both drift and diffusion are mechanisms that cause aerosol deposition, and in this sense, deposition can be seen as a result of the dispersal characteristics of the aerosol.<\/p>\n

From this, we can infer that the aerosol of electronic cigarettes is mainly composed of two parts:<\/p>\n

    \n
  1. \n

    Tiny particles that break free from the surface of the e-liquid due to the heat before reaching the evaporation temperature (diffusion).<\/p>\n<\/li>\n

  2. \n

    Liquid particles formed when the heated e-liquid reaches the evaporation temperature, and the high-temperature vapor encounters the normal temperature airflow and condenses (evaporation and condensation).<\/p>\n<\/li>\n<\/ol>\n

    For a detailed process of electronic cigarette aerosol generation, see Exploring the Working Principle of Vapor-Type Electronic Cigarettes.<\/p>\n

    In this issue, we have learned together about the formation, evolution, and transport mechanisms of aerosols, as well as the composition of electronic cigarette aerosols.<\/p>\n

    In the next issue, we have prepared the topic \"Study on the Deposition Pattern of Aerosols.\"<\/p>\n
