The physical models constitute a powerful tool for the design and optimization of complex hydraulic works on operation and implementation. In the project stage it allows to visualize the operation of the future work with the expected design conditions, and others more unfavorable conditions for it stability or good functioning, because we can controlled certain parameters that makes it possible to model scenarios that in prototype has a low probability of occurrence such as a probable maximum flood (PMF) or other that we don´t want to happen, such as damages or collapse of the structure. For the evaluations of existing works with design or functioning problems the physical models allow us to find optimized solutions. Currently due to the advancement of technology, we have access to high-performance numerical models, which allow us to perform the same analyzes as in physical models, but without large facilities. Due to the complexity of hydraulic phenomena, its numerical representation requires formulations that must be validated with experimental or prototypedata. The objective of this work is to demonstrate the utility of a physical model for the design and optimization of a hydro combined power plant, and its use for the validation of CFD simulations.

Keywords : physical model; CFD simulations; hydro combined power plant; optimization.
