Description

Heller Dry Cooling Tower CFD Simulation, ANSYS Fluent Training

A dry cooling tower is used as a means of indirect heat transfer between the working fluid (water) and the coolant(air). In a thermal plant, the working fluid (water) exits the condensers and then is pumped into a ring of heat exchangers. These heat exchangers are air-cooled, which means that they are cooled by natural air suction caused by a temperature difference between the inside and the outside of the cooling tower.

The more the temperature difference exists between outside air and working fluid, the stronger the temperature driving force. In the summer, the temperature difference between the working fluid and the ambient air decreases, which will result in a reduction in temperature driving force, making the cooling tower’s efficiency to decrease.

Therefore, the thermal unit has to lower its power production, and the rate of water consumption will increase drastically to cool the heat exchangers. In this project, the airflow inside a dry cooling tower (HELLER) is simulated and analyzed by ANSYS Fluent.
