“…e parameters have been introduced progressively in this study. Studies [17,21,26] have shown that a higher number of runner blades distort the vortex formation whereas a higher mass of the turbine is not beneficial in the efficient energy extraction process. Timilsina et al [6] concluded that the power output and runner speed decrease beyond some critical turbine weight.…”

“…is requires a higher number of blades, but increasing blade numbers can obstruct the water stream and change the flow regime. A higher blade number can increase drag which can overcome the power increase since lower efficiencies have been reported with higher blade numbers as well [17,26]. us, the number of blades is varied to determine the region for maximum runner efficiency.…”

Gravitational Water Vortex Power Plant (GWVPP) is an appropriate means to convert kinetic energy of water to rotational mechanical energy at the very low head site. This study aims to establish a basic reference for the design of the runner for the Gravitational Water Vortex Turbine (GWVT) with a conical basin. Seven different geometrical parameters have been identified for runner design, and the effect of these parameters on the system efficiency has been studied numerically and experimentally. The effect of these parameters has been studied over the range of speed with torque. The results from performance tests of these runners suggest that runner height is the most significant parameter to be considered in the design of a turbine runner for GWVPP with a conical basin. The results show that the efficiency of GWVT has improved up to 47.85% as obtained from experiments.

In Malaysia, usually an electricity energy is generated based on fuel sources such as coal and natural gases. Since the consumption of electric energy is keep increasing yearly, the extinction of these sources becomes one of the main problems in this industry. Thus, the country needs to spend higher expenditure to import these sources since it has limited quantity and it is not a renewable energy source. In addition, the usage of the coal as sources affect the environment. Therefore, this research proposed a prototype of mini generator based on the principle of water flow pressure. The prototype is developed based on the flow of water vortex that is influenced by gravity and has the capability to generate energy at low-head flat geographically area. A controller for this system is designed by using Arduino. The objective of this research is to study the efficacy of this type of generator since it is one of the techniques to generate electricity. The efficiency of the designed prototype is analyzed based on different radius value of the basin and the effect of different type of motor used to spin the turbine. The results show that the smaller radius of the basin and direct drive motor generate higher voltage if the system is being tested individually. However, if both characteristics are combined together, the highest radius of basin with direct drive motor produced bigger value of voltage.

Water and Wastewater treatment plants requires huge amount of energy operation cost. As per the energy demand, water companies require cost reducing and sustainable solution to produce energy. The generated energy should reduce its dependence on fossil fuel. For this study, different types of hydropower technology have been studied. And as per suitable criteria of wastewater treatment plants, Gravitational water vortex flow power plant which is one of the best low head and low flow rate basedhydropower technology have been selected. To determine optimum efficiency of power plant, a lab scale model will be prepared for selected hydropower technology. Generated electricity will be considered for co2 reduction energy and it can use in plant itself which can reduce its cost. Parameters of wastewater will be check for selection of appropriate turbine blade materials. This will be an innovative approach which can reduce the energy cost of wastewater treatment plants.
