Title: Numerical Modeling and Experimental Measurements of Water Spray Impact and Transport Over a Cylinder
Published: January 01, 2006
Abstract: This study compares experimental measurements and numerical simulations of liquid droplets over heated and unheated cylinders. The numerical model is based on an unsteady Reynolds-Averaged Navier Stokes (RANS) formulation using a stochastic separated flow (SSF) approach for the droplets that includes submodels for droplet dispersion, heat and mass transfer, and impact on a solid surface. The details of the droplet impact model are presented and the model is used to simulate water spray impingement on a cylinder. Computational results are compared with experimental measurements using phase Doppler interferometry (PDI). Overall, good agreement is observed between predictions and experimental measurements of droplet mean size and velocity downstream of the cylinder.
