Evaporation of water
Abstract:
Evaporation processes of water droplets is influenced by many factors such as pressure, temperature, velocity, diameter of droplets, and vapor diffusion coefficient especially, pressure which is an important factor affecting the evaporation time of liquid droplets. The evaporation of liquid droplets has been extensively studied both numerically and experimentally. Numerical simulation provides a cost-effective and reliable tool. Several studies have shown the benefit of using Computational Fluid Dynamics (CFD) is a tool to predict the evaporation processes. In this research, evaporation of water droplets in tubes under different pressure conditions (-1bar, -0.75bar, -0.5bar, -0.25bar, and atmosphere pressure) was studied through CFD simulations using Ansys Fluent software. The computational model is a droplet evaporation simulation by discrete phase model (DPM) and species transport model to examine, the evaporation in the cylindrical tube with a diameter of 0.4 m and a length of 3 m. Water droplets of 20 micron were injected into the tube at different internal pressures to study the effect of pressure on the evaporation time. The simulation results show that there is a clear relationship between pressure and evaporation time of water droplets. The evaporation time of the water droplets in the tube at different pressure conditions (-1bar, -0.75bar, -0.5bar, -0.25bar, and atmosphere pressure) are 0.158s-0.177s, 0.189s-0.192s, 0.202s-0.231s, 0.261s-0.314s, 0.376s-0.436s respectively. It was clear that the evaporation time is shorter at low pressure conditions
