MODELING OF THE LIQUID DYNAMIC COMPACTION SPRAY PROCESS

Mathematical formulations are developed to describe and predict the di stribution of spray density, and the morphologies and yields of spraye d deposits produced by Liquid Dynamic Compaction (LDC). The morphologi es of spray-deposited materials for various atomizer arrangements, inc luding both USGA circular and 50mm long USGA linear atomizers, and for various substrate manipulation are calculated according to developed formulations, which show excellent agreement with experimental results . Some of the applications of these models are presented, showing how to use developed models to calculate required substrate manipulation a nd atomizer arrangement to yield desired distribution of spray density and deposit morphologies without the need of extensive experimentatio n. Yield and deposition rate formulations are also presented.
