Evaluation of Reaeration by Convective Heat Transfer Coefficient
Publication: Journal of Environmental Engineering
Volume 144, Issue 2
Abstract
The reaeration-rate coefficient () is an essential parameter in water quality simulation because it aids predicting the water’s ability to assimilate organic pollutants. Several methods have been used to determine , but some of them are too expensive and others are not always accurate. A new method is presented in this paper, in which can be estimated using the convective heat transfer coefficient (h), which is obtained from a solid metal during cooling in a jet-agitated tank. The results show a very good correlation () between and h. This method is promising because of its simplicity and low cost. This new method took a short period of time to achieve its results and used simple materials. Other methods for determining reaeration-rate coefficients usually take more time and require more sophisticated materials than the proposed method.
