In this study, we assumed an emergency case in which a liquid solution mixed with multiple liquid chemicals leaks in an enclosed space. Numerical emission models of gas-phase chemical pollutants from mixed solution were developed as boundary condition for CFD (computational fluid dynamics) simulation. We focused on ammonia as chemical substances and conducted fundamental experiments in a small chamber to identify the transient gas-phase emission characteristics from binary mixture solution. Based on the results obtained from experiments, we developed numerical models in accordance with Henry's law and confirmed the reasonable prediction accuracy of our proposed numerical model.
