Editorial: Proccedings of the International Conference on Hydraulic Engineering Software "HYDROSOFT' 84",Portoroz,Yugoslavia,September 10-14, 1984.

Rezumat:

We have studied both experimentally and analytially the role of the local hydraulic resistance in systems provided with surge tanks and the corresponding role of the steady state volume of the air cushion in systems provided with an air chamber,evidentiating an intermediary domain of unsteady motions between slow and fast ones.For the mathematical model a special procedure of asymptotic expansion has been validated as giving more direct and simpler qualitative and quntitative description of the situation than computer simulations.
