Summary:

An optimization study involving both fluid-dynamic andthermostructural aspects has been carried out for a 2200 ccturbocharged engine head for marine applications. In thiscross-disciplinary problem, the structural and thermodynamicaspects have been decoupled. A preliminary set of CFD numericalanalyses of the cooling jacket layout has been performed, in orderto investigate critical aspects of the present configuration andimprove the cooling performance, by means of local flow patternsand flow distribution analysis. At a second stage, temperaturedistributions within the metal cast parts have been derived fromCFD in order to assess the fatigue strength of the component withstructural finite elements. A proper choice of both CFD methodologyand boundary conditions is carried out in order to determine atrade-off between computational effort and actual engine behaviorrepresentation. The proposed modelling procedure allows asensitivity study to be carried out of the engine head tovariations of the leading geometric parameters, thus devising anoptimized component.The methodology favored in this study is finally applied tocarry out a comparison between the basic configuration and afluid-dynamic improved solution, in order to estimate theeffectiveness of the design optimization on the fatigue strength ofthe component
