Resumen

PROVENZANO, P. G.; BARONI, F.  y  AGUERRE, R. J.. The closing function in the waterhammer modeling. Lat. Am. appl. res. [online]. 2011, vol.41, n.1, pp. 43-47. ISSN 0327-0793.

The closing valve law is a mathematical function that describes the speed variation of the fluid as it is closing. This reduction of the speed determines the shape of the pressure wave during the development of the water-hammer. A wide variety of closing modes exists, depending on the valve type and their operation, each one is mathematically given by a function. A generic function was formulated that allows to model an extensive variety of closing laws by means of a polygonal segmented structure. An algorithm has been generated that includes this closing law as boundary condition for describing the transitory. The pressure wave shape and amplitude depends on closing function in a unique relationship.
