Results of investigation of optical characteristics particles of soot and parameters of radiative heat transfer in marine diesel combustion chamber
Tendency's of development modern of marine diesels are connected foremost in increasing of their specific power, improvement of parameters economical and ecological characteristics. It determines emergence series of problems important which appears problem thermal of details made the combustion chamber. High loads level of thermal this details in marine diesels is on of basic reason in descent their exploitation security. Errors in calculation estimations of thermal and power deformable condition in details of combustion chamber in designing gets 30 - 80 % now. It causes necessity performance of mathematical models of heat transfer process in marine diesels combustion chamber. Purpose this paper is represent and discussion investigations results, made authors, by optical characteristics soot particles and radiation heat transfer in the marine diesel combustion chamber 6ChN 24/36. It demonstrate experimental that soot particles getting in marine diesel combustion chamber appear to small for optical aspect. Data mean on working cycle of local resulting radiation heat transfer fluxes for heat of cylinder, piston and liner of cylinder surfaces, represented in the paper, makes in designing to estimate value variable temperature intensity. It is very important for estimation of security combustion chamber details during exploitation.
