Study of Search Edge Strategy in Drawing Q-H Equilibrium Diagram of Fluid Network

摘要

Q -H equilibrium can reflect the state of fluid network visually and quantitatively, so it is an optimal means to analyze pipe system, and is a new method to express all the characteristics of a fluid network.We analyze the optimization problem of the Q -H equilibrium diagram for three — dimensional network, namely the problem of rectangle blocks are cut into more than one parts.An idea of studying the optimization problem of the Q -H equilibrium diagram for three -dimensional network by modifying search edge strategy is put forward.We put forward eight feasible search edge strategies, and the optimizing study of search edge strategy is done with the target is the total of cut rectangle blocks to be minimum. As a result, a better search edge strategy relative to the traditional one is obtained.
