“…Selective withdrawal has been studied for more than 40 years, and, in recent years, numerical methods are widely employed. A number of 1D, 2D, or even 3D numerical models were developed to predict the thermal structure or the withdrawn water temperature [ 1 – 4 ]. Some hydraulic analyses and extended theories of selective withdrawal were proposed.…”

Selective withdrawal from a thermal stratified reservoir has been widely utilized in managing reservoir water withdrawal. Besides theoretical analysis and numerical simulation, model test was also necessary in studying the temperature of withdrawn water. However, information on the similarity theory of the withdrawn water temperature model remains lacking. Considering flow features of selective withdrawal, the similarity theory of the withdrawn water temperature model was analyzed theoretically based on the modification of governing equations, the Boussinesq approximation, and some simplifications. The similarity conditions between the model and the prototype were suggested. The conversion of withdrawn water temperature between the model and the prototype was proposed. Meanwhile, the fundamental theory of temperature distribution conversion was firstly proposed, which could significantly improve the experiment efficiency when the basic temperature of the model was different from the prototype. Based on the similarity theory, an experiment was performed on the withdrawn water temperature which was verified by numerical method.

“…The model aims to more accurately simulate temperature dynamics and distribution, particularly near the water surface. Wind shear stress effects on temperature distribution have been proven negligible (Politano et al 2006) and therefore are not considered in this study.…”

“…A typical range for φ in a reservoir is from 0.02 to 0.2 m -1 (Smith and Baker 1981). Politano et al (2006) performed a sensitivity study of this parameter and demonstrated that a value of 0.5 ϕ = m -1 matched the field data. In this study, 0.5 ϕ = m -1 was used.…”

for their encouragement, guidance, and support throughout this research. I am extremely thankful and appreciative of all the effort and time Dr. Politano has spent helping me to expand my knowledge of fluid mechanics and numerical modeling. She and Dr. Weber have been greater teachers, wonderful mentors, and best role models to me. I consider myself very fortunate to have had the opportunity to learn from them. I would also like to thank the Hydro Research Foundation and the U.S. Department of Energy for providing me with a fellowship to fund this research. Their support made this work possible.
