Viscoelasticity reduces the droplet size in mucosalivary film fragmentation during intense respiratory events
Mogeng Li, Youssef Saade, Stéphane Zaleski +3
We examine the fundamental fluid dynamical mechanisms dictating the generation of bioaerosols in the human trachea during intense respiratory events such as coughing and sneezing,…
Experimental study of a turbulent boundary layer with a rough-to-smooth change in surface conditions at high Reynolds numbers
Mogeng Li, Charitha M. de Silva, Daniel Chung +3
This study presents an experimental dataset documenting the evolution of a turbulent boundary layer downstream of a rough-to-smooth surface transition. To investigate the effect of…
Recovery of the wall-shear stress to equilibrium flow conditions after a rough-to-smooth step-change in turbulent boundary layers
Mogeng Li, Charitha M. de Silva, Amirreza Rouhi +4
This paper examines recovery of the wall-shear stress of a turbulent boundary layer that has undergone a sudden transition from a rough to a smooth surface. Early works of Antonia…
Quantifying inner-outer interactions in non-canonical wall-bounded flows
Mogeng Li, Woutijn J. Baars, Ivan Marusic +1
We investigate the underlying physics behind the change in amplitude modulation coefficient in non-canonical wall-bounded flows in the framework of the inner-outer interaction mode…
Towards realistic simulations of human cough: effect of droplet emission duration and spread angle
Mogeng Li, Kai Leong Chong, Chong Shen Ng +6
Human respiratory events, such as coughing and sneezing, play an important role in the host-to-host airborne transmission of diseases. Thus, there has been a substantial effort in…
High humidity enhances the evaporation of non-aqueous volatile sprays
Mogeng Li, Detlef Lohse, Sander G. Huisman
We experimentally investigate the evaporation of very volatile liquid droplets (Novec 7000 Engineered Fluid) in a turbulent spray. Droplets with diameters of the order of a few mic…
Growth of respiratory droplets in cold and humid air
Chong Shen Ng, Kai Leong Chong, Rui Yang +3
The ambient conditions surrounding liquid droplets determine their growth or shrinkage. However, the precise fate of a liquid droplet expelled from a respiratory puff as dictated b…
