Abstract
An analytical model has been developed for the process of liquid spray evaporation into a high temperature gas stream. In this model, the calculation scheme utilizes the cellular approach in-which each cell is regarded as a control volume and the gas-droplet interaction is considered. Based on an experimental data, droplets of a liquid spray are classified into several size distribution groups, The conservation laws of mass, momentum and energy are applied to each group considering the evaporation and diffusion of droplets, Predictions of gas-droplet Flow-field, trajectories of the Individual droplets, rate of evaporation and change of size distribution of the spray droplets have been obtained. An experimental verification of the prediction results has been carrid out. An optical arrangement is used for measurements of sire distribution of spray droplets into a high temperature gag stream. The comparison shows a reasonable agreement of the results based on the analytical model with the experimental measurements for each of droplet size distribution and changes of Sauter Dean diameter at different axial distances from the injection nozzle plane.
