| Popis: | The requirement of fresh drinking water is one of the most severe problems all over the globe. The humidification dehumidification systems have shown promising outcomes while being used for water desalination. The performance of humidification-dehumidification water desalination systems is generally presented in the form of productivity of the humidifier or dehumidifier. Humidification being the predecessor process plays a crucial role in the performance of the Humidification - Dehumidification system. This work presents the theoretical and experimental investigation of bubbler humidifier. The performance of the bubbler humidifier is studied under various operation conditions such as: hole diameter, bubble column height, air mass flow rate, temperature of air and temperature of water inside the humidification chamber. A mechanistic model for bubbler humidifier is presented and validated with the experimental results. The Relative Humidity (RH) of air was achieved in the range of 68% to 97% for various operation conditions while the highest RH of air was recorded 97% for 1 mm of hole diameter, 7 g/s of mass flow rate of air, 60 °C of temperature of water, 48 °C of temperature of air, 7 cm of Height of water Column. |
