Numerical Simulation in Atmospheric Water Generator By Ansys Fluent

Abstract

Water crisis and providing water is one most essential problems that humans are facing. There are several ways for water extraction, depending on population and resources. In this simulation, water is extracted by a cooling tower from humid air. Humid air enters the buried pipes with fans. Then the air reaches the cooling tower. Because of the difference in temperature between air and pipes, air temperature decreases. After this process, there is an amount of residual water, extracted from humid air. The extracted water can be used as drinkable water or for agricultural purposes. In this project, we simulate airflow by Ansys Fluent. Then by using air condition relations, combined with the numerical solution, the amount of extracted water can be calculated. In addition, in the first half of the day, because the temperature difference between airflow and pipes’ wall is more than at the end of the day, the amount of extracted water is different throughout the day. We can obtain that in the second half of the day, the airflow temperature is more than the tower’s temperature, so the air is cooling the tower and preparing the system for the next day.
