There is heat loss with an engine, which accounts for about 40% of thermal energy occurred in an engine. Therefore, in order to calculate the heat transfer from burned gases to the combustion chamber wall surface, it is necessary to evaluate the heat transfer coefficient on the combustion chamber wall surface. However, it is difficult to find the heat transfer coefficient. Therefore, the equation is required to estimate the heat transfer coefficient with generality. In this study, we made the T type thermocouple which is said the Cu-Con heat flux probe, and measured heat flux on the combustion chamber wall surface by setting the Cu-Con heat flux probe at various places (cylinder head, cylinder liner and piston head) of the combustion chamber of the engine (TRE-1). In addition, in order to confirm generality, heat flux was measured at the cylinder head and cylinder liner of the different engine (R52). Furthermore, the both measurement results were expressed by the number of no dimensions of Nusselt number (Nu) and Fourier number (Fo), and were compared every measurement point. As a result, the similar tendency was confirmed on both cylinder liners. 宮崎大学工学部 Faculty of Engineering, University of Miyazaki 2015-07-31 jpn departmental bulletin paper VoR http://hdl.handle.net/10458/5581 https://miyazaki-u.repo.nii.ac.jp/records/4732 AA00732558 05404924 宮崎大学工学部紀要 Memoirs of Faculty of Engineering, University of Miyazaki 44 173 178 https://miyazaki-u.repo.nii.ac.jp/record/4732/files/engineering44_173-178.pdf application/pdf 1.1 MB 2020-06-21
