Abstract

Objectives: Tidal Energy, one of the clean and green energy sources, has the potential to replace the conventional fuels like Coal and Petroleum. In this paper, an attempt has been made to measure the tidal range in Chennai and theoretical calculations have been performed to find how much energy can be harnessed from tidal source. Methods/Statistical Analysis: Chennai city, one of the metropolitan cities of India has been selected as the study area. The Chennai port which is the second largest port in India is the specific site for the tidal measurement using the Tidal gauge. Tidal gauge, usually measures the change in the sea level with respect to a datum for a month period. From the measured tidal range, the power output that can be harnessed from a tidal barrage arrangement has been theoretically calculated. Findings: At Chennai port, there has been a maximum spring tide of about 1.2 m. By approximating the tidal range to 1 m and by considering a tidal barrage having a km2 area, with electrical conversion efficiency of 0.2, the total annual electricity generation capacity is approximately 10 GWh per year is theoretically calculated. Application/Improvement: By increasing the electrical conversion efficiency to 0.4 to 0.5, the production can be more than 20 GWh power. Which definitely helps the government in replacing the conventional and problematic Non-Renewable energy sources

Abstract

Objectives: SS 321 is an austenitic stainless steel material which finds application in many fields. The coating on SS 321 by Graphene and SiC are used to improve the thermal resistance and strength of SS 321. Methods/Statistical Analysis: Coating of Graphene and SiC on SS 321 was done by spin coating and drop casting. The coated samples were subject to laser ablation followed by flame treatment. Then treated and untreated samples were characterized by SEM, EDX and Surface roughness measurement. Findings: From the SEM images the coating was found to be uniform and from the EDX measurement, the composition of the samples has been calculated and no observable impurities found. From the surface roughness measurement, it is evident that the roughness parameter changes from untreated to treated samples but there were no sign of cracks, which proves that the coating by Graphene and SiC on SS 321 is viable and increases the strength of the material. Application/Improvement: By doing Atomic Force Microscopy and thermal resistance and strength measurements on Graphene SiC coated SS 321 can give further authentic result or by choosing CNT like materials for coating, may improve the performance of SS 321.
