Abstract EN
The flow characteristics of raw sewage directly affect the technical and economic performance of sewage-source heat pump systems.
The purpose of this research is to characterize the flow characteristics of sewage by experimental means.
A sophisticated and flexible experimental apparatus was designed and constructed.
Then the flow characteristics of the raw sewage were studied through laboratorial testing and theoretical analyses.
Results indicated that raw sewage could be characterized as a power-law fluid with the rheological exponent n being 0.891 and the rheological coefficient k being 0.00175.
In addition, the frictional loss factor formula in laminar flow for raw sewage was deduced by theoretical analysis of the power-law fluid.
Furthermore, an explicit empirical formula for the frictional loss factor in turbulent flow was obtained through curve fitting of the experimental data.
Finally, the equivalent viscosity of the raw sewage is defined in order to calculate the Reynolds number in turbulent flow regions; it was found that sewage had two to three times the viscosity of water at the same temperature.
These results contributed to appropriate parameters of fluid properties when designing and operating sewage-source heat pump systems.
