Large-eddy simulation of droplet-laden cough jets with a realistic manikin model
Indoor and Built Environment, 2021Three-dimensional computational fluid dynamic (CFD) methods were used to simulate a cough jet that contains droplets. The turbulent cough flow is modelled using large-eddy simulation with a dynamic structure model.

Effect of velocity and radius distribution on jet breakup
The Physics of Fluids, 2022The focus of this paper is on the effect of velocity and radius distribution on jet breakup. A theoretical model is established to analyze and predict the velocity distribution along the jet, which is physically and mathematically continuous.

Droplet sliding on a rotating surface mediated by an asymmetric gas layer
The Physics of FluidsDroplet impact can be widely seen in many applications, such as aircraft anti-icing, spray coating, and inkjet printing. In these applications, droplets always impact moving surfaces. The impact of droplets on a rotating surface and the gas layer beneath

Numerical analysis of the interaction between a droplet and an air boundary layer
The Physics of FluidsThe deformation and movement of droplets are widely utilized in many industrial applications. The present work investigates the evolution of a single droplet interacting with an air boundary layer numerically and validated by wind tunnel experiments. The

A modified phase-field three-dimensional model for droplet impact with solidification
International Journal of Multiphase Flow, 2019A modified phase-field three-dimensional model has been developed to simulate the spreading of an impacting droplet undergoing solidification. The model is based on the numerical solution of the Cahn-Hilliard equation coupled with the Navier-Stokes ...
