dc.description.abstract1Charge air cooling is essential for the efficient operation of marine diesel engines. This work presents the results of research on the characteristics of long-range heat transfer surfaces for marine diesel engines. Elliptical and flat-oval tubes were considered. This study was carried out using mathematical models that consisted of the equations for energy conservation, motion, continuity, and state. The RSM turbulence model was used to close the system of equations. To solve the resulting system of equations, the RANS approach was used, which was implemented in the software package Code Saturne with a free license and the SimScale cloud service. The mathematical model was verified by comparing the model results with the experimental results obtained using a prototype heat-exchange surface of a charge air cooler at a test bench. The discrepancy between the theoretical and experimental heat transfer coefficient α was ≤ 8.3 %. An estimate of the compactness of smooth elliptical and flat-oval tube banks compared with round ones was carried out. A 19.6 % increase in compactness was obtained for elliptical tubes and 17.5 % for flat-oval tubes. Based on the profiled finning surfaces, it is possible to improve their thermohydraulic characteristics by up to 40 % when using them together with elliptical tubes compared with round ones and up to 26 % when using them with flat-oval tubes.
