Abstract
Fossil fuels have remained at the backbone of the global energy portfolio. With the growth in the number of factories, population, and urbanization; the burden on fossil fuels has also been increasing. Most importantly, fossil fuels have been causing damage to the global climate since industrialization. The stated issues can only be resolved by shifting to environment friendly alternate energy options. The horizontal axis hydrokinetic turbine is considered as a viable option for renewable energy production. The aim of this project is the design and optimization of a diffuser for horizontal axis hydrokinetic turbine using computational fluid dynamics based surrogate modeling. The two-dimensional flat plate airfoil is used as a benchmark and flow around the airfoil is simulated using Ansys Fluent. Later, computational fluid dynamics analyses are carried out for baseline diffuser generated from the flat plate airfoil. The performance of this diffuser was optimized by achieving an optimum curved profile at the internal surface of the diffuser. The response surface methodology is used as a tool for optimization. A maximum velocity augmentation of 31.70% is achieved with the optimum diffuser.
Highlights
Fossil fuels have been considered as a major energy source for the global economic engine
In one way or the other, most the industries and domestic units rely on energy produced by fossil fuels
The contribution of CO2 emissions from industrial processes and fossil fuel combustion accounted for about 76% of the total anthropogenic greenhouse gas (GHG) emissions increase between 1970 and 2010 [1]
Summary
Fossil fuels have been considered as a major energy source for the global economic engine. In one way or the other, most the industries and domestic units rely on energy produced by fossil fuels. The fossil fuels have caused degradation of our environment. This damage to the global climate has reached an alarming point and its impact has already been felt in recent decades. The contribution of CO2 emissions from industrial processes and fossil fuel combustion accounted for about 76% of the total anthropogenic GHG emissions increase between 1970 and 2010 [1]. The governments around the globe, with the cooperation of the United Nations (UN) and regulatory bodies, are paying an ever-increasing attention to the environmental issues associated with fossil fuels
