The usage experience of momentum and kinetic energy equations
The usage experience of momentum and kinetic energy equations. Girgidov A.D. // Izvestiya B.E. Vedeneev VNIIG. 2007. V. 248. P. 122-128. 3 illustrations, 4 references. In the integral form the independence of momentum and kinetic energy equations for incompressible liquid is stipulated by the terms containing liquid viscosity. At the same time by the example of the tasks about outflow through Bord orifice and spillway with wide threshold it was shown that joint solution of these equations for incompressible liquid allowed to have got non-trivial and practically useful results. Conformity of the evaluated and experimental values of discharge coefficients confirmed validity of the received hypotheses about forces distribution at the control volume boundaries.
