JTC Sponsored Final Year Projects AY 2014-15 


Project ID: GE-27AB
Project Title: Chemical Methods in Dewatering Clayey Slurry For Land Reclamation
School: School of Civil and Environmental Engineering (CEE)
Solo/Dual Project: Single Project
NTU Supervisor: Tan Soon Keat (Assoc Prof)
JTC Supervisor: James Lee
FYP Student: Andi
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.

JTC Supervisor: Ng Kian Wee
FYP Student: Sim Hong Xun
Project Description:

Due to Singapore’s prominent role as hub in Asia, the demand for warehousing, distribution centers, and industrial production sites will continue to grow. However, land in Singapore is a scarce resource. These two factors together motivate us to investigate the potential of developing highly efficient transportation of goods between ports to (aboveground & underground) distribution centers and industrial workplaces. The proposed Western Corridor (see Fig.1) is a prime example of a region that requires careful logistics planning in order to maximize its potential as an efficient industrial site.

We aim to develop novel ICT technologies to plan for, analyse and optimize the transportation of industrial/consumer goods aboveground and underground in industrial areas.

Project ID: B481
Project Title: Parametric study of evaporation water recovery for side draft cooling tower to improve overall water efficiency
School: School of Mechanical and Aerospace Engineering (MAE)
Solo/Dual Project: Solo Project
NTU Supervisor: Zhao Dan (Assistant Prof)
JTC Supervisor: Loh Wai Soong
FYP Student: Chia De Jing Colman
Project Description:

The purpose of cooling tower is to reject thermal energy (heat) using the evaporation of water as the heat-transfer mechanism.

Thermal energy generated by the electrical, industrial, electronics equipment, lighting and etc, is generally transferred to a cooling water loop circulating between the building spaces and the chiller. A second loop carries heat rejected from the chiller to the cooling tower which transfers the heat to air through sensible and latent heat exchange processes. Evaporation, blowdown and drift are the main water losses mechanism in cooling tower, where evaporation amounted the largest loss. The amount of water loss through evaporation from cooling tower is approximately 3 gallons per minutes (gpm) per 100 tons of cooling. The objective of the current project is to study the recovery of evaporation water to improve the overall water efficiency.

Project ID: GE-27AB
Project Title: Chemical Methods in Dewatering Clayey Slurry For Land Reclamation
School: School of Civil and Environmental Engineering (CEE)
Solo/Dual Project: Dual Project
NTU Supervisor: Tan Soon Keat (Assoc Prof)
JTC Supervisor: James Lee
FYP Student: Andi / Cham Junbi
Project Description:

The use of chemicals such as flocculants has been reported to be an effective solution for the management of fine materials/wastes with high water-content, e.g. slurry and natural fine tailings. The separation of water and solid particles can be noticeably accelerated with the addition of chemicals. Based on the literature review and some preliminary studies, it is suggested that this method can also be adopted in land reclamation when clay slurry is used as fill material.

However, the flocculation process is complex, and successful adoption of flocculants for slurry dewatering depends on many parameters, such as soil type, water content of slurry, concentration of chemicals, method of introducing chemicals into slurry, and mixing conditions (mixing speed and duration), etc. A parametric study may be carried out to investigate the influences of these factors on the flocculation and dewatering process of clay slurry. These experimental results will have potentially practical application for the future adoption of clay slurry as a fill material in land reclamation in Singapore. This FYP is sponsored by JTC. Up to $2000 will be provided by JTC for the project.

Project ID: ME-06
Project Title: Microscale study on fatigue behavior of fiber-reinforced concrete
School: School of Civil and Environmental Engineering (CEE)
Solo/Dual Project: Solo Project
NTU Supervisor: Yang En-Hua (Assistant Prof)
JTC Supervisor: Ng Kian Wee
FYP Student: Lim Xin Ni
Project Description:

Fiber reinforced concrete (FRC) has been widely used and is gaining its popularity over new constructions. In infrastructures like tunnel and pavement, FRC shows better resistance to repeated fatigue load than normal concrete due to the fiber-bridging across cracks; however, strategically improving FRC’s fatigue performance has been a bottleneck for material engineers, mainly due to lack of knowledge on dynamic fiber-matrix interaction on microscale level. In this project, you will focus on the effect of load frequency and fiber/matrix compositions on fatigue behavior of single fibers embedded into matrix. This will be an experience of interdisciplinary scientific research, which connects civil engineer’s demand and material scientist’s techniques. This project is sponsored by JTC.Up to $2000 will be provided by JTC for the project.
