Investigation of dilution performance depending on discharge conditions via physical modelling

With the increase of industrialization, various facilities are being established on the water shores. There are some cases when these facilities negatively affect the marine ecosystem. One of them is thermal discharges. Thermal discharges can create negativities in the marine ecosystem. The reason for the occurrence of thermal discharges is that facilities such as power plants, iron and steel factories use large bodies of water such as the sea as a coolant to perform the cooling process. In order to prevent the occurrence of such negativities, the temperature change of the receiving medium depending on the temperature of the discharge water is restricted by law. Therefore, it has become important to determine the best dilution and the most economical system. In order to learn this, 3 different systems have been tested in a laboratory environment. In our first experiment, free falling jets, in our second experiment, jets parallel to the water were created from the water surface, and in our third experiment, a secondary reservoir was made on the water surface and discharged through three holes. Thermal clouds formed by jets have been studied.
