| Abstract | Singapore’s lack of ideal geographic location and natural resources created the need to generate renewable energy to offset its carbon footprint. The characteristics of the wind in tropical climates, which is turbulent flow in multiple directions, encouraged the use of the Vertical Axis Wind Turbine (VAWT), but the natural wind conditions are not feasible to power the VAWT due to inconsistencies in wind speed and direction. Exploring forced ventilation situations, it can either use a mechanically ventilated exhaust or wind energy recovery from accelerating objects. Mass Rail Transport (MRT) trains, the electrical rail system in Singapore, has high mass while accelerating at high velocity. This is why it is capable of producing large draft of increased air velocity. The simulation results from FLUENT ANSYS show that the forced wind draft is of laminar flow (up to 6 m/s) at the sides of the MRT train and diversifies to turbulent flow (up to 8 m/s) at the front face of the MRT due to the drag force. The laminar flow will enable the wind turbine to accelerate the spin momentum of VAWT supporting a greater energy output. The understanding of the vertical profile of wind speed specifications of wind turbines, has led to an invention of a unique idea of integrating a hydraulic lift in the main body of the wind turbine to maximize its potential of harvesting wind energy at greater altitudes due to increase in wind speed by 6%. From the movement of MRT trains, the energy that can be harvested from wind using a 2kW vertical axis wind turbine is calculated as 600,000 W/year. Based on simulation, with a 5 meter increase in the height of the turbine, the efficiency of power generation increases by 0.2 percent. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
