Shell and tube type heat exchanger is a component of clove essential oil distillation apparatus using hot steam as hot fluid and water as a cold fluid, each flowing in opposite directions. The distillation system in the field still uses a condenser or straight pipe heat exchanger, where the temperature of the hot fluid that comes out is still considered high enough so that the indication of effectiveness is not optimal. To optimize the effectiveness, a shell and tube heat exchanger is designed with a numerical method based on Fluent CFD using a hexagonal pipe geometry in tube layouts of 30°, 60°, 45°, and 90° inline and staggered arrangement and counter flow type. This study varied the cold mass flow rate (ṁc) = 0.052; 0.059; 0.083; 0.1; 0.12 Kg/s, while the mass flow rate of the hot fluid is constant. The simulation results obtained that the maximum effectiveness occurred at a mass flow rate of 0.052 kg/s of 5.45% staggered layout and the minimum occurred at a mass flow rate of 0.12 kg/s of 4.01% on an inline layout. The results of this research are also expected to help the community which can be used for various essential oils.

“…The tube arrangement has an influence on the energy performance of tube and shell heat exchangers, Sachin Kallannavar et al (2020) studied the effect of variation of four types of tube arrangement 30°, 90°,60°and 45°, for a tube and shell heat exchanger with circular tube. Arania & Moradi (2019) segmental baffles and combined segmental-disk baffle with two types of circular and triangular ribbed tube.…”

“…They also numerically studied a shell and tube heat exchanger with conventional baffles and provided a detailed comparison of the different types. Kallannavar et al [2] conducted a comprehensive study to explain the process parameters related to the design features of shell and tube heat exchangers. The researchers observed that heat transfer is better in the counter flow than in the parallel flow.…”

This numerical study examines the effects of the baffles added to the fluid (oil) flow path to be cooled in a shell and tube heat exchanger. The heat transfer rate in the case without baffles is compared to the cases where the baffles are added in the oil flow path. The comparison shows a remarkable increase in heat transfer, but on the other hand leads to higher pumping costs due to a higher pressure loss. CFD simulation can optimize the design of shell and tube heat exchangers by changing the number, size and position of the baffles. The CFD simulation package used here is the commercial software ANSYS Fluent © . The CFD model contains all details of the geometric and material properties, so that the solution reflects all physical phenomena such as rate of heat transfer, temperature, velocity and pressure distributions within the computational domain. The approach used here provides heat exchanger manufacturers with valuable design information without having to produce prototypes that are based not only on expensive, but also on time-consuming trial and error methods.
