Investigating the Value of Parallel Pipeline Projects for Water Supply: A Contingent Valuation Study in South Korea Water (IF 3.4) Pub Date : 2024-03-11 Yongsuk Hong, Jungwoo Shin, Hyunhong Choi, JongWuk Ahn
Parallel pipeline projects can contribute to ensuring a safe and stable water supply and preventing or mitigating losses caused by water pipeline accidents. However, because these projects require a significant investment, feasibility tests are essential prior to their implementation. Considering the public nature of the water supply, the direct beneficiaries of the project and people from other regions

Research on the Influence of Lateral Force and Pressure Fluctuation on the Stability of a Rotary Energy Recovery Device in the Desalination System Water (IF 3.4) Pub Date : 2024-03-12 Tianzhuang Ye, Xinchao Hu, Kaiyuan Wang, Yunfei Qu, Jiancong Lu, Renjiang Yuan, Lei Jiao
The rotary energy recovery device (RERD) plays an important role in reverse osmosis (RO) desalination; however, few investigations on the formation and influence of lateral force on the RERD rotor have been published. The transient characteristics of lateral force and its relationship with pressure distribution and fluctuation in the clearance were analyzed via computational fluid dynamics (CFD) simulation
