Mixture mathematics model of two-phase turbulence flows and its application

In this paper, turbulent form of the mixture model is deduced by Renoldys averaging, and Heat buoyant force is added to the Averaged Momentum Equation. An office, including two man bodies, two computer and six lights, is simulated numerically, It is shown that the computational results is well agreed with the experimental results and the modified two-phase flow model is perfect for the indoor environment with heat source.
