Integrating Top-Down and Bottom-Up Approaches Improves Practicality and Efficiency of Large-Scale Ecological

Zhaowei Ding,Hua Zheng,Jun Wang,Patrick O'Connor,Cong Li,Xiaodong Chen,Ruonan Li,Zhiyun Ouyang,

Engineering doi: 10.1016/j.eng.2022.08.008

Abstract: •A new framework for SESs integrating top-down and bottom-up approaches was established.Top-down approach-based spatial planning, emphasizing hierarchical control within government structuresThus, spatial optimization planning that integrates both top-down and bottom-up approaches can resultin more practical and effective ecological restoration than top-down approaches alone.

Performance of a bi-layer solar steam generation system working at a high-temperature of top surface

Jinxin ZHONG, Congliang HUANG

Frontiers in Energy 2023, Volume 17, Issue 1,   Pages 141-148 doi: 10.1007/s11708-021-0725-4

Abstract: Many efforts have been focused on enhancing the vapor generation in bi-layer solar steam generation systems for obtaining as much pure water as possible. However, the methods to enhance the vapor temperature is seldom studied although the high-temperature vapor has a wide use in medical sterilization and electricity generation. In this work, to probe the high-temperature vapor system, an improved macroscopic heat and mass transfer model was proposed. Then, using the finite element method to solve the model, the influences of some main factors on the evaporation efficiency and vapor temperature were discussed, including effects of the vapor transport conditions and the heat dissipation conditions. The results show that the high-temperature vapor could not be obtained by enhancing the heat-insulating property of the bi-layer systems but by applying the optimal porosity and proper absorbers. This paper is expected to provide some information for designing a bi-layered system to produce high-temperature vapor.
