An Automated Tool for Smart Water Network Partitioning
Water Resources Management, 2013Co-Authors: Armando Di Nardo, Giovanni Francesco Santonastaso, Michele Di Natale, Salvatore VenticinqueAbstract:Water Network Partitioning (WNP) represents the application of the “divide and conquer” paradigm to a Smart WAter Network (SWAN) that allows the improved application of techniques for water balance and pressure control. Indeed, these techniques can be applied with greater effectiveness by defining smaller permanent network parts, called District Meter Areas (DMAs), created by the insertion of gate valves and flow meters. The traditional criteria for the design of network DMAs are based on empirical suggestions (number of properties, length of pipes, etc.) and on approaches such as ‘trial and error’, even if used together with Hydraulic Simulation software. Nevertheless, these indications and procedures are very difficult to apply to large water supply systems because the insertion of gate valves modifies the original network layout and may considerably worsen the Hydraulic performance of the water network. The proposed tool, based on some graph partitioning techniques, commonly applied in distributed computing, and on an original optimisation technique, allows the automatic design of a WNP comparing different possible layouts that are compliant with Hydraulic performance. In this paper, the methodology was tested on a real case study using some performance indices to compare different WNPs. The proposed tool was developed in Phyton and integrates graph partitioning, Hydraulic Simulation techniques and a heuristic optimisation criterion. It allows the definition of DMAs with resulting performance indices that are very similar to the original network layout.

thermal Hydraulic Simulation of absorber tubes in linear fresnel reflector solar thermal system using relap
Renewable Energy, 2016Co-Authors: Sudhansu S Sahoo, Suneet Singh, Rangan BanerjeeAbstract:This paper presents thermal Hydraulic modelling and Simulation in the absorber tube of a Linear Fresnel Reflector (LFR) solar thermal system is carried out. The system is modelled using two-phase flow Simulation software, RELAP5/MOD3.4. Although, RELAP5 is very commonly used in nuclear engineering design and Simulation, it can be used for the Simulation of solar thermal systems. Unlike other thermal systems like refrigerators and nuclear industries, there is significant heat loss from the surface of the absorber tube in a solar thermal system, which varies significantly with the temperature of the absorber tube wall. The recently developed temperature dependent heat loss has been incorporated in RELAP5 for variable net heat flux studies. The implementation of the temperature dependent heat losses has been verified by comparing the results obtained from RELAP with those obtained by Homogeneous Equilibrium Model. Parametric studies are carried out using verified RELAP model for different values of heat flux, mass flux, inlet subcooling and inlet pressure. The developed model can be considered as an effective tool for better and effective absorber LFR tube design under designed conditions.
