A Distributed Parameter Model for the Drying of Multicomponent Aerosol and Sessile Droplets
نویسندگان
چکیده
The new distributed parameter model is formulated for the purpose of the investigation of a drying of suspended and sessile droplets of multi-component solutions. The main feature of this model is the division of a droplet/wet particle into the shells and formulating the mass and heat balances for each shell, which have a shape of spheres in a case of aerosol particles and a shape close to the cylinders in a case of sessile droplets. Presented model takes into account the crust formation during the second stage of drying. This effect is neglected in existing models of the phenomenon. The model predicts the dimension and a shape of particle or formed deposits. It also indicates the possibility of a segregation of components when their solubility and diffusion coefficients are different.

Growth of solid conical structures during multistage drying of sessile poly(ethylene oxide) droplets.
Sessile droplets of aqueous poly(ethylene oxide) solution, with average molecular weight of 100 kDa, are monitored during evaporative drying at ambient conditions over a range of initial concentrations c(0). For all droplets with c(0) > or = 3%, central conical structures, which can be hollow and nearly 50% taller than the initial droplet, are formed during a growth stage. Although the formatio...
متن کاملSurface-guided templating of particle assemblies inside drying sessile droplets.
The particles suspended inside evaporating sessile droplets can be assembled into microscopic objects with long-ranged ordered structure. The air-water droplet interface guides the assembly and determines the shape of the resulting micropatches. We report the results of a systematic study of the mechanism of interface-templated assembly on substrates of controlled contact angle. The kinetics of...
متن کاملControlling particle deposit morphologies in drying nano-particle laden sessile droplets using substrate oscillations.
Sessile water droplets containing nano-silica particles are allowed to evaporate in the presence of driven substrate oscillations at chosen frequencies. Different mode shapes are observed at different oscillation frequencies. As reference, the evaporation of the same droplets is also observed under stationary conditions i.e. in the absence of any oscillations. For all cases, the deposit structu...

A generalized simplified model for describing the dynamic behavior of distributed parameter systems is proposed. The various specific characteristics of gain and phase angle of distributed parameter systems are investigated from frequency response formulation and complex plane representation of the proposed simplified model.

متن کاملStatistical Modeling for Oblique Collision of Nano and Micro Droplets in Plasma Spray Processes
Spreading and coating of nano and micro droplets on solid surfaces is important in a wide variety of applications including plasma spray coating, ink jet printing, DNA synthesis and etc. In spraying processes, most of droplets collide obliquely to the surface. The purpose of this article is to study the distribution of nano and micro droplets spreading when droplets impact at an oblique a...
