There is increased interest in, and concern about, deposition and corrosion phenomena in cornbust ion systems containing inorganic condensible vapors and particles (salts, ash). To meet the need for a computationally tractable deposition rate theory general enough to embrace multielement/component situations of current and future gas turbine arid magnetogasdynamic interest, we present a multicomponent chemically "frozen" boundary layer (CFBL) deposition theory and demonstrate its applicability to the special case of Na,SO. deposition from seeded laboratory burner combustion products. The coupled effects of Fick (concentration) diffusion and Soret (thermal) diffusion are included, along with explicit corrections for effects of variable properties and free stream turbulence. The present formulation is sufficiently general to include the transport of particles provided they are small enough to be formally treated as heavy molecules. Quantitative criteria developed to delineate the domain of validity of CFBL-rate theory (Section 5) suggest considerable practical promise for the present framework, which is characterized by relatively modest demands for new input information and computer time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
