Modeling of heat and mass transfer processes in phase transformation cycle of sprayed water into gas: 1. The calculation peculiarities of droplet phase transformation parameters

Abstract

An unsteady phase transformation cycle of sprayed water droplets was numerically modelled in humid air. This cycle combines condensing and unsteady evapo-ration modes. Method influence of droplet diameter selec-tion in iterative cycle was estimated for calculated droplet phase transformation parameters. A comparative analysis of modeling results was performed, when a droplet coarse-ness stability condition is applied in iterative cycle or drop-let diameter is used in ordinary iteration, when it was de-fined in former iteration. Phase transformation cycle was modelled for droplets in combined conduction-radiation case. Assumption of droplet size stability in iterative cycle inadequacy at „droplet“ task numerical solution algorithms.
