N2 - The present study is aimed to investigate the oscillation effects on the frost formation and the liquid droplet solidification on a cold plate in atmospheric air flow. A microscopic image system is used to observe the structure of the frost layer, and an electrodynamic shaker is designed to oscillate the cold plate at various amplitudes (D) and frequencies (f). The physical parameters considered in this study include the velocity, temperature, and relative humidity of the air (V, Ta, and φ), as well as the surface temperature of the cold plate (Tw), which is varied by adjusting the cooling refrigerant temperature (Tref). The ranges of the physical variables considered in this study are: 2 ≤ V ≤ 8 m/s, 18 ≤ Ta ≤ 30 °C, 40% ≤ φ ≤ 70%, -18 ≤ Tref (and Tw) ≤ 0 °C, 40 ≤ D ≤ 100 μm, and 100 ≤ f ≤ 200 Hz.
