Hydraulic Calculation Software Development on the Heating Pipeline Network Based on Visual Basic

Thesis based on the improved framework of the hydraulic calculation model and the calculation method, with the utilization of the Visual Basic program accompany with the Access database, the application software applied for hydraulic calculation on the general heating network goes a certain versatile. High degree of accuracy of this software brings about the convenient utilization. During the process of the variable condition calculation, the program shall distinguishes the topological structure automatically and regulates the iteration of the incidence matrix under the circumstances of the merely modification for the varied pipeline and corresponding information of the nodes. Eventually, we took the variable condition hydraulic calculation of the multiple heat sources network as an example. Then obtained and analyzed the flow parameters of pipe network, the pipeline flow, head loss, the ratio frictional resistance and so on.
