Abstract

An assessment of recirculation flow in Jatiluhur reservoir is conducted based on two dimensions turbulent κ-ε model. The numerical model was developed using finite difference method where hydrodynamic equation was solved by the combination of Mc Cormack and splitting methods. The κ-ε equation is solved using quickest scheme in convection term, central scheme in diffusion term and Euler scheme in reaction term. The simulations were done for maximum incoming flow during the rainy season and the dry season. Model results are compared to field measurement from which it is found that rainy season scenario has shown better agreement. Maximum incoming flow released in the rainy season could generate a boundary layer greater average velocity and more recirculation flow than that in the dry season. Further development is required to get more accurate results for the case with less average velocity.
