Abstract (2. Language): 
Fuel Oil heat exchanger used in aircraft’s fuel system in order to prevent the formation of ice due to residual water in fuel is a shell-tube heat exchanger. This paper is a comparative study of shell and tube heat exchanger with segmented baffles and helical baffles to obtain maximum heat transfer characteristics. The Cold fluid used in the FOHE is the Jet-a fuel. 3D model and flow volume extraction was done using CATIA for the two different baffles. Since we are comparing the performance of segmented and helical baffles, we have simplified the analysis model and compared with only cold fluid domain and applied the temperature of the hot fluid to the hot pipe walls. For the given mass flow rate of the cold fluid, heat transfer rate and pressure drop were analyzed for the segmented and helical baffles and reported in this article. Analysis results from Ansys Fluent showed that the pressure drop is less with better heat transfer in helical baffles than the segmented baffles.
