Techno-economic, energy, and exergy analyses of invasive weed gasification for hydrogen enriched producer gas production

This research work deals with the examination of the techno-economic, exergy, and energy analyses of biomass gasification of the invasive weed Parthenium hysterophorus (PHP) using Steam - Carbon dioxide (CO2) as a gasifying agent with the support of simulation modeling for sustainable energy conversion process. The aim of this work is to simulate the gasification process through consideration of the impacts of various operating factors on gasification. This study attains the gradual increase in hydrogen (H2) concentration from 51% to 63% along with the rise in carbon monoxide (CO) from 14.5% to 19% using Aspen Plus simulation. CO2 falls concurrently from 24% to 13.5%. The findings demonstrate significant advancements over earlier studies in terms of both gas composition and overall system performance. A computational model has been developed for the estimation of energy performance indicators such as total energy input, and energy consumed per mass of biomass gasified, which are used in the determination of the system's energy efficiency. The exergy analysis of the system is performed to assess the system's total losses in terms of efficiency gathered from the system's exergy ratios. The economic analysis evaluates the system's economies of scale by gas production at ₹.15/kg and long-term sustainability. The proposed system has been found with the potential to produce a high yield of alternative energy from PHP with increased economic efficiency and lower environmental impact

Design and Analysis of Bus Body Right Side Frame

Conventional designs of bus bodies have more weight and which will affect the carrying capacity, performance and resulting higher fuel consumption. This project describes a new approach and specific design procedure for more lightweight bus body design. The purpose of this project is to redesign the parameters like gauges, materials, geometry/shapes, topology variables, weld pitch, joints for improving the structure so that the total weight of the bus is reduced. A light weight design of bus body structure is designed and structural analysis of the body structure under different load conditions is done. The modeling will be done on solidworks 2014 and analysis part will be done on ANSYS 14

ALUMINIUM HYBRID COMPOSITES APPLICATION IN AUTOMOTIVE INDUSTRY

Strict requirements that are put on mechanical constructions from the side of increase of manipulation periods and reduction of their weights, consequently of their prices as well, implicate improvements and applications of new composite materials with matrices of lightweight metals. Composite materials with metal conditions are used for engine connecting rod, cylinders, pistons, piston rings disc and drum brakes, shafts and for further rudiments in automotive and air travel industry. The most essential types of metallic materials is composite materials with a matrices of aluminium alloys due to a set of their positive properties. Enhancement of mechanical, mainly tribological properties of amalgam composites were delivered by the use of definite reinforce materials such as SiC, Al2O3 and graphite in demarcated weight or volumetric part. The modern developed hybrid composites are with a aluminium matrices to be having a mostly maximum resistance to wear, maximum specific stiffness and upper resistance to fatigue. By the increase of quantities of manufactured components made of hybrid composites, decrease of their prices is tempted that even promote enlarge their applications. The applications of aluminium hybrid composites are reflected from the aspect and with the emphasis on automotive industry

Design and Fabrication of Movable Headlight System in Automotive Vehicles

This paper presents the hardware of movable Headlight System for motorized vehicles. Headlight System is an active safety system, where the head lamp alignment control system rotates the right and left headlights independently and keeps the beam as parallel to the curved road as possible to provide better night time visibility to driver. In this system use rack and pinion arrangement which give drive to the optical axes on which headlight are attached so when a tie rod arms are moved with steering arm that give predefined motion to the wheel as well as headlights system
