文摘
- •
Direct Numerical Simulation (DNS) of turbulent two-phase flows are conducted.
- •
A detailed investigation of the turbulence-scalar interaction (TSI) term is performed.
- •
The topology of the scalar field is modified as the liquid/gas interface is approached.
- •
In this zone the orientation of the scalar field tends to minimize the TSI.
