Efficient geometric design of fishery Lake by means of computer simulation

Fish breeding plays an important role in economic factors and health system of community as nourishment and economic point of views. Thereby, in order to increase efficiency, regarding breeding parameters, such as biological, environmental and hydraulic characteristics are of great concerned. In the present paper, hydraulic and hydrodynamic such parameters of fish habitat for its optimum designing are concerned. Thereafter, hydraulic efficiency coefficient as an effective factor were investigated. In order to calculating hydraulic efficiency, a three dimensional flow solver in fishery Lake for obtaining flow filed characteristics is utilized. Navier-Stokes governing equations in Cartesian system by means of finite volume techniques are used for three dimensional modeling. In addition k-ε two-equation turbulence model is exploited for calculating stresses due to turbulence.
