A second-order moment two-phase turbulence model is derived for simulating liqui d-bubble two-phase turbulent fluctuations and their interaction in liquid-bubble flows.To reduce the computer memory storage and computation time,algebraic exp ressions of Reynolds stresses and two-phase velocity correlations are used,inst ead of their transport equations.The proposed model is used to simulate liquid a nd bubble velocities,gas volume fraction,liquid and gas Reynolds stresses and turbulent kinetic energy in a ...
