Abstract Connecting rod acts as a moderator in between the crank and piston. Its primary function is to convert linear motion into reciprocating motion by transmit the pull and push from the piston to crank. Connecting rods are generally made with carbon steel and aluminium alloys because of high strength and stiffness. In the present work, static and modal analysis is carried out to determine the dynamic behaviour of connecting rod by considering deformation, strain and stresses when made with Beryllium alloy using Ansys software. These parameters help in identifying a section of failure due to stresses induced.

Abstract The concept of Smart cities is widely emerging now days. A smart city can be defined as internet of networking the physical devices vehicles-smart devices which are embedded with electronics, software sensors, actuators and network connectivity that enables the objects to collect and exchange data. The ability of human and computers to learn and interact from the things which include sensors, services and other internet connected objects are provided by internet of things (IoT). Smart cities can work as a tool for controlling the rapid urbanization and various problems caused by the ever increasing urban population. The implementations of the smart technologies can increase the value of the city. Smart city concept introduces new practices and services that highly impacts policy making and planning. The understanding of IoT systems will make us to know the cyber world with one physical world and will fundamentally change and make powerful human interaction with the world.

Abstract The aim of this present work is to enhance thermal performance characteristics in a heat exchanger tube by studying: (i) multiple twisted tapes in different arrangements; (ii) Al2O3 nano particles with different concentrations as the working fluid. The tube inserted with twisted tapes showed superior thermal performance factor when compared with plain tube, due to continuous multiple swirling flow and multi-longitudinal vortices flow along the test tube. The higher number of twisted tape inserts led to an enhancement of thermal performance that resulted from increasing contact surface area, residence time, swirl intensity and fluid mixing with multilongitudinal vortices flow. Moreover, arrangement of twisted tapes in counter current was superior energy saving devices for the practical use, particularly at low Reynolds number. Experiments were conducted within range of 2200Re 700.Investigation was carried out for the fully developed laminar convective heat transfer and friction factor characteristics in a plain tube and fitted with twist tubes . Using water with Al2O3 nano particle as a working fluid yielded a higher thermal performance than using pure water. The tube inserted Al2O3 /water nano fluid at concentration of 0.3% by volume provided the highest thermal performance factor 1.59, where heat transfer rate and friction factor increased to 3.52 times and 11.7 times of those in the plain tube with water as the working fluid.

Abstract Escalating fuel prices and future carbon dioxide emission limits are creating a renewed interest in methods to increase the thermal efficiency of engines beyond the limit of in-cylinder techniques. One promising mechanism that accomplishes both objectives is the conversion of engine waste heat to a more useful form of energy, either mechanical or electrical. This paper reviews the use of internal combustion engine exhaust waste heat recovery focusing on Organic Rankine Cycles since this thermodynamic cycle works well with the medium-grade energy of the exhaust. Selection of the cycle expander and working fluid are the primary focus of the review, since they are regarded as having the largest impact on system performance. Results demonstrate a potential fuel economy improvement around 10% with modern refrigerants and advancements in expander technology

Abstract — Parabolic collectors are used to collect the energy from the sun. And water purification is one of the fore most issue now a day a human is facing in rural areas, urban areas and also chemical industries. In the present work a case study has been carried out at SUES campus pharmacy laboratory to supply the distilled water and to carry out the experiments. The design for the Solar distillation plant works under the principle of concentrating the Sun’s energy on a thermally conducting water tube to heat up the flowing water to vapour, there after it gets condensed and is later collected it in a pure form of water used for laboratories. The distillation is the requirements for this specific design are a target for distilling 80 litres of water per day regularly with low maintenance.

Abstract The movement toward sustainable building designs is being driven largely by environmentally sensitive building owners and/or their prospective tenants. There are also heightened concerns about assuring a proper indoor environment at all times and conditions for the building occupants. In addition to providing temperature control, a fully effective HVAC system must also address many other indoor environmental issues that affect occupant comfort, productivity and health such as ventilation air, air distribution, humidity control, noise levels, etc .As these owners and their consultants weigh their HVAC system alternatives, they often find that chilled beam systems are the ideal "green" solution for many buildings. There is also a persuasive overall comfort and economic argument for the use of active chilled beam systems over other of the more conventional systems choices. While relatively new in India, chilled beam systems are proven and are successfully being used in Europe since a decade. The chilled beam system promotes excellent thermal comfort, energy conservation and efficient use of space due to the high heat capacity of water used as heat transfer medium. It is an energy efficient HVAC technology which works on dry cooling principle. The goal of this project is to design a Chilled Beam Air-Conditioning System for a hotel building which is followed by a complete examination of its energy conservation potential in comparison with a conventional Chilled Water Air-Conditioning System for the same building.

Abstract A well-developed road network forms an integral part of the development of any nation. The lack of resources available and their ever-increasing cost of materials and energy have motivated highway engineers to explore new alternatives in building new roads and rehabilitating the existing ones. A weak sub-grade has been and still is one of major concerns to pavement design engineers due to its potential contribution to permanent deformation in flexible pavements, particularly in lowvolume thin pavements. In such situations, the natural condition of poor sub-grade soils needs to be improved by suitable modification techniques to meet project requirements. Improving the strength of the sub-grade soils using additives is one such alternative. In the present study the performance of nonwoven geo-textile, interfaced between soft sub-grade and unbound gravel in an unpaved flexible pavement system, is carried out experimentally, utilising the California Bearing Ratio (CBR) testing arrangement. In order to evaluate the performance of the reinforcement the CBR load – penetration graphs are drawn. The relation of both soft sub-grade soil and soft sub-grade geo-textile soil separately. Soil properties and variations of load carrying capacity is found using CBR Tests. Optimum percentage of fibres and optimum size of geo-textile is also found using CBR Test.
