عنوان انگلیسی Investigation of Shell Side Overall Performance of a Novel Shell-and-Double-Concentric –tube Heat Exchanger with Simple and Perforated Helical Baffles
چکیده انگلیسی مقاله In this study, the overall performance of a heat exchanger shell-and-double-concentric-tube with simple and perforated helical baffles is investigated in the shell side of the heat exchanger using ANSYS FLUENT 19.2. A comparison between the shell-side with simple helical baffles of the heat exchanger (SHB-SDCTHEX) and the one with perforated helical baffles (PHB-SDCTHEX) using numerous mass flow rates is carried out. For the perforated helical baffles heat transfer rate , thermo-hydraulic performance  and effectiveness  are around 26.7%, 55.5% and 26.6% higher than the same parameters for the simple helical baffles of the heat exchanger, respectively. It is also observed that the flow and temperature distribution for the perforated helical baffles are more uniform with higher flow turbulence than the simple helical baffles of the heat exchanger. So, the perforated helical baffles could be a better choice for the designers and manufacturers with respect to the simple helical baffles of the heat exchanger.
