The flow parameters, which controlled the heat transfer phenomena in the coolant channel of the piston, are identified; the experimental facilities and program will be established in accordance with the parametric conditions experienced by a real marine diesel engine. The experimental result for the flow within smooth-walled duct under the reciprocating motion will be used as the reference datum to assess the results for the study of heat transfer augmentation. As an attempt to enhance the cooling performance, the ribs will be installed in the coolant channels which flow was orthogonal mode for the piston moving direction. Finally, the results obtained for the tests with heat transfer augmentation devices will be compared with the smooth-walled test results.
