"Current Scenario of Solar Energy Applications in Bangladesh: Techno-Economic Perspective, Policy Implementation, and Possibility of the Integration of Artificial Intelligence" (https://doi.org/10.3390/en16031494)

Abstract

Bangladesh is blessed with abundant solar resources. Solar power is considered the most desirable energy source to mitigate the high energy demand of this densely populated country. Although various articles deal with solar energy applications in Bangladesh, no detailed review can be found in the literature. Therefore, in this study, we report on the current scenario of renewable energy in Bangladesh and the most significant potential of solar energy’s contribution among multiple renewable energy resources in mitigating energy demand. One main objective of this analysis was to outline the overall view of solar energy applications in Bangladesh to date, as well as the ongoing development of such projects. The technical and theoretical solar energy potential and the technologies available to harvest solar energy were also investigated. A detailed techno-economic design of solar power applications for the garment industry was also simulated to determine the potential of solar energy for this specific scenario. Additionally, renewable energy policies applied in Bangladesh to date are discussed comprehensively, with an emphasis on various ongoing projects undertaken by the government. Moreover, we elaborate global insight into solar power applications and compare Bangladesh’s current solar power scenario with that of other regions worldwide. Furthermore, the potential of artificial intelligence to accelerate solar energy enhancement is delineated comprehensively. Therefore, in this study, we determined the national scenarios of solar power implementation in Bangladesh and projected the most promising approaches for large-scale solar energy applications using artificial intelligence approaches.

Abstract

Baffle is commonly used to improve the performance of the shell and tube heat exchangers. In this work, effect of the baffle spacing to the performance of a shell and tube heat exchanger has been examined experimentally. The length and diameter of the shell of the heat exchanger is 500 mm and 60 mm, respectively. The number of the tube is 4. The inner and outer diameter of the tube is 13.8 mm and 15.8 mm, respectively. In this study baffle spacing is varied from 71 mm, 55 mm and 45 mm with increasing baffle number to 6, 8,10 respectively. The hot water mass flow rate was fixed to 4.5 Litres/min and cold-water mass flow rate was varied from 6,9,12,15 Litres/min. Using the experimental data heat transfer coefficient, Nusselt number, effectiveness has been evaluated. The results show that effectiveness Increases when the baffle spacing decreases. The maximum effectiveness with 4 different baffle configurations (6 baffle, 8 baffle, 10 baffle, without baffle) are 35%, 48%, 55% and 16%. The maximum increment of heat transfer coefficient for 10 no of baffle is 144.02% with respect to without using baffle and 53.13% with respect to 6 no of baffle for mass flow rate of 15 litres/min.

Abstract

One of the finest renewable sources is hydropower from the river. Compared to wind or solar energy, hydropower is more predictable. Bangladesh has been blessed with many rivers with velocity of water flow. The savonius rotor is one of the finest forms of turbine for generating electricity utilizing the kinetic energy of natural water resources. There are many ongoing researches of using savonius water turbine to use it as a current turbine. In this study, the performance of a savonius water current turbine has been analyzed in respect to Bangladesh. To Analyze the performance, the Padma, the Ganga, the Brahmaputra, the Meghna and the Karnaphuli’s water velocity has been taken into account. A Computer Aided Design (CAD) model of two blades of savonius water turbine was designed in SOLIDWORKS and analyzed with Computational Fluid Dynamics (CFD) in ANSYS simulation software. The performance has been analyzed with the comparison of flow rate, torque generated, Tip Speed Ratio (TSR), velocity and RPM. The velocity has been collected for the Padma, the Ganga, the Brahmaputra, the Meghna and the Karnaphuli as 4.86 ms-1, 4.50 ms-1, 3.5 ms-1,1.5 ms-1 and 0.44 ms-1 respectively
