Numerical modelling of penstock flow in dam

This paper presents the numerical modeling on the flow in dam penstock structure using conventional finite volume method (FVM) simulation software, ANSYS Fluent. The water flows in the bottom outlet section that comprised of four penstocks were successfully simulated. The numerical model was validat...
