The goal of the proposed project is to develop a computational fluid dynamics model of the Davis hydro turbine, so that its performance can be assessed and improved before it becomes a commerically available product. A numerical implementation of the model will be used to estimate important characteristics of the turbine, such as its power coefficient, power quality, and average torque. The reliability of the mathematical model will be tested by comparing the numerical results to the experimental ones. If the model is found to be reliable, it can be used to optimize key parameters of the turbine propellers, and consequently improve the performance of the Davis hydro turbine.
