Abstract
In this paper a methodology is presented to predict the water drop trajectories at a given fan operating condition (i.e., face velocity), coil height and for a range of water drop diameters. Water drop carry over horizontal distances have been calculated as a function of evaporator coil height, water drop diameters, and face velocities for an evaporator unit. The simulated data has been compared with the experimental data. Initial results have shown that the model can predict the water drop trajectories fairly well.
The developed model can be used to calculate the maximum horizontal distances the water drops will be carried over with the airstream for a range of water drop diameters. This is very important information to the design engineers for properly designing the evaporator units.
