MARENGO-MOGOLLON, H.; OCHOA-ALVAREZ, F.J.  e  CORTES-CORTES, C.. Pressure Fluctuations on the Bed of Surge Tank at the H.P. Zimapan, Hgo., with Different Arrangements Studied on Hydraulic Model, with the Lowest Operation Conditions. Ing. invest. y tecnol. [online]. 2009, vol.10, n.4, pp.321-330. ISSN 2594-0732.

In this paper, the pressure fluctuations of the surge tank in the Zimapan Hydroelectric Project are compared in a hydraulic model. The shaft is located lateral, over the conduction tunnel and in the simple form (permitting the tunnel entering the shaft), with and without orifice plates taking into account the demand and supply condition of energy with the minimum level of water of the conduction. It was determined the hydraulic efficiency and it was found that it was the best constructive option.
