Effect of Twisted Tape Insert on Heat Transfer Enhancement in Counter Flow Co Axial Double Pipe Heat Exchanger using CFD

The twisted tape has great potential as a device for enhancing heat transfer. Twisted tapes hold the advantage over other techniques as they ease of installation and operation. From the previous studies, it is also found that there were rare researches on a combination of twisted tape insert and nanofluids. Therefore, the scope of the present study is concerned with the enhancement of the double pipe heat exchanger performance through twisted tape insert. To achieve these aims, a numerical model was constructed in order to investigate the effect of twisted tape on the heat transfer coefficient. This study investigates the heat transfer characteristics of Counter flow co axial double pipe heat exchanger using Al2O3 water nanofluids by inserting twisted tape turbulator of pitch 25mm inside the inner tube. The Al2O3 water nanofluids 0.4 1.6 particle volume concentrations were used. The simulation were conducted under the turbulent flow in the Reynold’s number range of 4000 Re 20000. It is found that from the computational outcomes, the heat exchanger with twisted tape insert unveiled the best Nusselt number of 487.24 at Re=20,000 at 1.6 vol. of nanoparticle. By comparison, the Nusselt number of double pipe heat exchanger with twisted tape insert is 8.27 higher than with wire coil insert.

Experimental Approach to IoT Based Secure Online Voting System using Raspberry PI and Extended Facilities with Arduino UNO

Electronic voting machine has developed and used in many countries all over world, India is one of them who has world’s largest democracy. Some politician takes advantage of electronic voting machine to submit vote on behalf of absent people or died peoples. This is the most important and controversial topic in India. Most of the people doesn’t have a faith on EVM machine and Opponent parties in India still having issue with EVM. Recently in India during Loksabha election 2019 election commission of India started using VVPAT to synchronize votes. But still some opponents have doubt on Electronic voting machine and VVPAT too. So all opponent parties are requesting to conduct a election on ballot paper which is easy to vote but hard to count and time consuming system. Hence we try to overcome some disadvantage of EVM by introducing Advance Electronic voting machine to avoid bogus and fake voting. This advance Electronic voting machine is IoT Internet of Things based machine which is directly linked with Governments servers to access and compare voters valid data. This project is designed for integrating Electronic Voting Machine with the data of the voter as in the Aadhar.

A Research on Affordable Housing

The need for achieving sustainability in social housing has been widely acknowledged in the literature and society in general. Housing problems occur both in rich and poor communities across the planet. The target of this research is to review housing problems which cause unwholesome environmental conditions. The tactic used could also be a review of educational articles, textbooks, internet materials, news articles and publicly available materials on housing problems. Onward taking up any work for its execution, the owner or builder should have a thorough knowledge about the volume of work that can be completed within the limits of his funds or the probable cost that may be required to complete the proposed work. It is hereby necessary to modulate the probable cost or estimate for the proposed work from its plan and specification. Otherwise, it may happen that the work has to be stopped in the middle of construction due to shortage of funds or materials. At present there is plenty of cost effective technology which can be used for construction of affordable houses at large scales. But due to lack of their technical knowledge, they are still not in use. In future with the increase of their technical aspect, these technologies can be used for mass construction of affordable housing projects in India for the poor and needy.

Fabrication and Study the Effect of Mechanical Properties of Coconut Shell Powder and Rice Husk

In this present work experimental investigation has been carried out to fabricate and study the effect of CSP and Rice husk powder at different weight percentages 30, 40 and 50 with epoxy resin. An epoxy resin has very good electrical insulation properties and outstanding mechanical strength including tensile and flexural. The composite material is fabricated by using hand lay up method. Then the composite material is tested on universal testing machine UTM for tensile strength. The addition of CSP and Rice husk powder weight percentage has improves the mechanical properties. it is observed that the strength of the composite material is increased with the increase in the CSP and Rice husk powder content in epoxy matrix.

Prediction of Size and Elemental Compositions of Groundnut Shell Ash and GGBS using SEM and EDX Analysis

Large volume of Groundnut shell and Ground Granulated Blast Furnace Slag GGBS are disposed directly from the industries on the land without doing any further treatment. These discharged waste materials are making nuisance to the environment, when it was discarded over the earth surface and thus making the environmental issues and illness to the peoples. Therefore, it is planned to investigate the possibilities to use the Groundnut shell and Ground Granulated Blast Furnace Slag GGBS in the form of ash for the production of concrete in the construction industries for the replacement of cement. In this works, it is planned to perform the SEM and EDX analysis to predict the elemental components and size of Groundnut Shell Ash GSA and GGBS. By analyzing the results obtained by conducting the SEM and EDX analysis, it was examined that the size of the GSA and GGBS are less than 75m and 45Âµm respectively. The GSA and GGBS contains large amount of oxides of calcium, magnesium, potassium, silica and aluminium. The components and their proportions of the minerals of the GSA and GGBS are very match with the cement. Hence, it is suggested that the GSA and GGBS could be replaced for the partial replacement of cement for making concrete. Also, the size of the GSA and GGBS are less than the size of the cement particles and hence it will help to enhance the strength and durability properties of concrete matrix.

Design of Low Power Dynamic Comparator using Reversible Logic

The Performance of circuits based in CMOS transistor logic is close to reaching its limit. A new efficient system or technology is needed to provide solutions to computing and integration issue. The proposed work addresses the above circumstance by implementing the reversible logic in dynamic comparator so that the number of transistors can be reduced. The critical path is made minimal so that the routing is reduced which makes the delays negligible. Reversible computing has its applications in computer security and transaction processing and also in those areas which require high energy efficiency, speed and performance.

Performance Analysis of Different Radiation Pattern using Genetic Algorithm

In most applications of antenna arrays, side lobe levels SLLs are commonly unwanted. Especially, the first side lobe level which determines maximum SLL is the main source of electromagnetic interference EMI , and hence, it should be lowered. In this thesis proposed a very simple and powerful method for the synthesis of linear array antenna. This method reduced the desired level of side lobe level SLL as well as to steer the main beam at different different angle. In this paper we draw the radiation pattern for N = 24 elements with main beam are shifted by 30Â° and the simulation result analysis by Matlab R2013a tool.
