Dual Project

NTU Supervisor:

Tan Soon Keat (Assoc Prof)

JTC Supervisor:

FYP Student:

Chua Feng Jun and Lim Hak Soon

Project Description:

To cater for future economic development in Singapore, more land reclamation needs to be carried out. However, there is severe shortage of granular fill materials (sand) as reclamation fill. On the other hand, a large amount of soft cohesive soil is generated through infrastructure development and maintenance dredging works. The disposal of these excavated spoil and dredged materials becomes a problem in the land-scarce Singapore Island. These two problems can be overcome if an innovative method can be developed to use these abundant soft materials to replace the acute shortage of granular fill material for land reclamation works. The use soft soil as fill materials is not used extensively because of the limited knowledge on the behavior of soft soil during the processes of filling and soil improvement. This project is proposed to investigate the feasibility of using soft soil as fill materials. The students are expected to address two research issues: (1) the quality of discharge from reclamation sites where soft soil is used as fill materials, and (2) the settling behavior of soft soil as fill materials.

Student A : The student focuses on the quality of discharge from reclamation sites where soft soil is used as fill materials - scope: comprehensive desktop studies, laboratory experiments and data analysis.

Student B : focuses on the settling behavior of soft soil as fill materials - scope: detailed desktop studies, laboratory experiments and data analysis.

FYP Student:

Huang Ziping Brenda

Project Description:

Sand used for land reclamation in Singapore contains a variable amount of shell content. The amount of shell content will affect the engineering properties of the granular material. As the compressive strength of the shell content is much lower than silica sand, high shell content may adversely affect the shear strength of the sand. The objective of the project is to study the impact of various amounts of shell content on shear strength of sand used for land reclamation.

Project Description:

The Chilled Ceiling is proposed to be test-bedded in JTC Summit building to
determine the performance and financial viability of the system for application in buildings in the tropics. The Chilled Ceiling is an energy saving air distribution technology for building space cooling that has been implemented in cities of temperate countries such as Germany and China, but not common in cities of tropical climate countries like Singapore. We need to test if this technology can be used in our tropical environment. The project will also provide a local reference of the technology that could potentially lead to wider market adoption in the tropics and spin-off to more R&D in this area.

Project Description:

The energy storage is essential in the development of smart grids and the utilization of the renewable energy resources. The large-scale energy storage have the potential to contribute to (1) improve energy efficiency and flexibility of national electricity grids, through load leveling / peak shaving, and (2) grid stabilization of power derived from renewable energy based sources. The all-vanadium redox flow battery energy storage system (VRB-ESS) has to date shown the greatest potential for large-scale energy storage applications with long cycle life and high energy efficiencies of over 80% in large installations. Using the same element in both half-cells, it prevents cross contamination and has a theoretically indefinite electrolyte life. It also exhibits a low cost for large storage capacities. The proposed project evaluates the feasibility of VRB-ESS on the building applications through extensive experimental tests and thorough numerical simulations. Both the experimental results and the mathematical modelling and simulations will make significant contributions to the VRB-ESS implementation in the development of green buildings. This project will focus on the VRB applications for buildings by combining with renewable energy sources.
