“…The main research efforts over the last five years have been focused on investigating spirally or transversally corrugated tubes and channels, fins or inserts of wavy strip tapes, and other techniques that allow disturbance of thermal boundary layers [8][9][10][11][12][13][14][15][16]. A concept of fluted tubes was investigated by Srinivasan et al [12].…”

“…The next step is to perform mathematical calculations and modeling simulations of the heat exchanger model based on the data obtained. It is data related to ships engine power and ships speed, input data in heat exchanger simulation and modelling, with the hope that it can be known which heat exchanger design has the best characteristics of performance [11,12].…”

Pollution of the marine environment has become a global issue, including marine pollution from ballast water. The impact is it can damage ecosystems and even affect humans. Therefore, pollution from ballast water is something that must be prevented by ballast water treatment. In this research, the author carried out a modeling simulation on a heat exchanger with a mechanical-type ballast water treatment method by utilizing the heat generated by the ship’s engine. Heat is used to kill microorganisms. So that the ballast water becomes cleaner than without treatment. In this research, the calculation of the need for heat exchangers on certain types of ships with certain sizes is carried out. In this calculation, the ship used is a container type with 3 categories based on cargo capacity and ballast tank capacity. Then the heat from the exhaust gases is used to heat the ballast water of the ship. The simulation results show that the maximum ballast water temperature of each ship category is in the range of 68-75 C. With this temperature, it is sufficient to kill and reduce microorganisms in the ballast water.
