“…Taflin and Davis (8) and Zhang and Davis (9) used electrodynamic levitation to hold a single droplet in a low Reynolds number gas stream, and they varied the gas flow rate to alter the Peclet number. Zhang and Davis proposed an interpolation formula based on the low-Pe asymptotic solution of Kronig and Bruijsten and the high-Pe solution of Levich (10).…”

“…Optical resonances or structural resonances are the natural modes of oscillation of a dielectric medium when illuminated by a source of electromagnetic radiation. Since Ashkin and Dziedzic (1977) first recognized the utility of resonant light scattering for measuring the optical properties of microparticles, a number of laboratories have applied the principles to study evaporation and growth (Richardson et al, 1986a, b;Taflin and Davis, 1987), and Tzeng et al (1984) measured evaporation and condensation rates of liquid droplets using resonances in fluorescence spectra. Numerous theoretical studies of resonance structures have been published, such as those of Chylek et al (1978Chylek et al ( , 1983, Barber et al (1982), and Conwell et al (1984).…”

Two light-scattering techniques have been applied to study the kinetics of droplet evaporation and attendant interfacial phenomena. The first technique, which is particularly useful for noisy data, utilizes the fast Fourier transform of phase function data (intensity vs. scattering angle) to obtain the size by comparing the phase function with LorenzMie theory. The second method applies optical resonance measurements to obtain very precise measurements of size and/or refractive index as functions of time. The techniques have been used to measure the slow evaporation of multicomponent and single-component organic microdroplets, rapid evaporation of water droplets, and rapid evaporation of droplets of aqueous solutions and surfactant solutions. The experiments were performed in an electrodynamic balance, which was used to suspend single microdroplets in a polarized laser beam. Rapid evaporation rate data yield information on the surface temperature, and data for surfactant solution evaporation show that insoluble monolayer formation at the microdroplet surface reduces the evaporation rate by a factor of 200. In addition, it is shown that droplet explosion due to surface charge effects can occur well below the Rayleigh limit of charge.

“…Since relatively large jet velocities could be sustained in a SHEL, Zhang and Davis (1987) and Taflin and Davis (1987) used the SHEL to measure the effects of gas flow on droplet evaporation rates, and they compared their results with theory for Peclet numbers in the range Pe < 10. Here, the Peclet number is defined by Pe = 2aU,/D1,, where Dl, is the diffusion coefficient for the vapor in the surrounding gas.…”
