Mathematical Model and Analysis of Dual Axis Solar Tracking Mechanism
Abstract: AbstractThe recent years have seen solar energy as one of the most potential candidate for electric power generation. However, the low output conversion efficiency still remains the matter for concern. The maximum power energy output relies on myriad environmental factors. This paper investigates the role of radiation intensity and panel position for better output efficiency and proposes an efficient dual axis solar tracking mathematical modelling that tracks the sun irrespective …

Fresnel Lens with Advanced Fabricated Setup for Day Long Production of Hot Water
Abstract: AbstractThis work has been aimed to tap the solar energy source from Fresnel lens and utilize it to produce hot water or steam. The fabricated setup consists of a large spot Fresnel lens which concentrates the sun's rays into a 1 cm2 square spot onto a copper tube with temperature reaching up to 200°C. This concentrated heat is focussed on copper tube absorber to heat the water, the hot water …

Natural Convection Heat Transfer from Annular Step Fins and Annular Triangular Fins Fitted over a Vertical Cylinder
Abstract: AbstractNatural convection heat transfer from a vertical cylinder with annular step and triangular fins has been studied numerically at various Rayleigh numbers within the laminar range. The computations were carried at a constant fin spacing to tube diameter ratio of 1. In the current study, numerical simulations of Navier-Stokes equation in support with the energy equation are conducted for a vertical cylinder with annular step fins as well as triangular …

Evaluating the Effect of the EGR Rate on the Performance and the Emission of VCR Engine Operating on Jatropha Biodiesel Blends
Abstract: AbstractThe modern diesel engines running on biodiesel employ many techniques to encounter strict exhaust emission norms. Among the many techniques suggested to mitigate the NOX emission from the compression ignition engine, the Exhaust Gas Recirculation (EGR) system is being employed extensively. The EGR curtails the proportion of the oxygen in the mixture and lowers the flame temperature inside the cylinder. This research is intended to investigate the influence of the …
