Optimization of Process Parameters of Tungsten Inert Gas Welding by Taguchi M...ijsrd.com
Tungsten Inert Gas welding (TIG) is one of the most important joining technologies in welding-related fabrication. High quality weld joints without spattering and slags qualify this welding technology for the major part of metals. As the filler-metal supply is separated from the arc, the molten pool can be controlled in the best way possible an advantage which ensures the quality of the execution of the weld but entails a relatively low deposition rate and welding speed. When manufacturing consumer products where appearance is of importance; then the choice has to be TIG welding. Jobs that call for code requirements such as nuclear work, piping, and high profile consumer goods often require at least the first weld in the pipe joint to be TIG welding for an effective bond. In some cases all the passes on a multi-pass pipe weld may have to be TIG welding, if demand has high quality and code requirements.

performance evaluation of mhd renewable energy source for electric power gene...EECJOURNAL
Electrical energy is very vital in recent times and modern living. In the day-to-day running of businesses and homes, we need energy at least to power our appliances. In south-eastern geopolitical zone of Nigeria, we have coal, oil and gas in abundance. MHD electrical power generation technology is one the technologies many developing countries apply to alleviate electrical power problems. This work therefore studied some MHD configurations that will perform optimally best with reference to the available coal and gas in southern Nigeria. These naturally available resources can be harnessed towards boosting electrical power generation. The study investigated the performance of different plant configurations based on open-cycle MHD generators fed with coal and gas. The power plants analysis has been performed by developing an integrated model required to characterize mass and energy balances of each system component and the electro-magnetic equations needed to solve the energy balance in the MHD generator. System efficiency was achieved by considering the IG-MHCC, B plant configuration where a high temperature heat recovery level has been introduced.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

4. INTRODUCTION
Magneto hydrodynamics (MHD) is the academic discipline which studies
the dynamics of electrically conducting fluids. Examples of such fluids
include plasmas, liquid metals, and salt water. A magnetohydrodynamic
generator (MHD generator) is a magnetohydrodynamic device that
transforms thermal energy and kinetic energy into electricity. MHD generators are
different from traditional electric generators in that they operate at high
temperatures without moving parts.
The field of MHD was initiated by Hannes Alfvén, for which he received
the Nobel Prize in Physics in 1970.
6. PRINCIPLES OF MHD POWER
GENERATION
Faraday’s law of electromagnetic induction : When an electric
conductor moves across a magnetic field, an emf is induced in it, which
produces an electric current .
8. PRINCIPLES OF MHD
POWER GENERATION
According to the principle of conventional generator the conductors
are made of copper strips.
In MHD generator, the solid conductors are replaced by the gaseous
conductor, an ionized gas. If such a gas is passed at a high velocity
through a powerful magnetic field, a current is generated and can be
extracted by placing electrodes in suitable position in the stream.Moving
through a magnetic field experiences a retarding force as well as an
induced electric field and current.
11. TYPES OF MHD
Open Loop System
Closed Loop System
Seeded inert gas system
Liquid metal system
12. OPEN LOOP SYSTEM
In an open cycle MHD system ,atmospheric air at very high temperature
and pressure is passed trough a strong magnetic field.Coal is first processed
and burnt in the combustor at high temperature and pressure.Then a seeding
material is injected(Potassium Carbonate) to increase the conductivity.It’s then
expanded through a nozzle and passed through the magnetic field.during the
expansion the positive and negetive ions at high temperature move to the
electrodes and constitute current.In this cycle same air can’t be reused,that’s
why this is called open cycle MHD.
14. CLOSED LOOP SYSTEM
As the name suggests the working fluid in a closed cycle MHD is circulated in
closed cycle.Here inert gas or liquid metal is used as working fluid. Liquid metal has
high electrical conductivity, so the temperature of combustion material need not to
be high.Hence there is no inlet and outlet as open loop for atmospheric air.the
process is simplified to great extent.
Two types of closed loop system are
Seeded inert gas system
Liquid metal system
15. SEEDED INERT GAS
SYSTEM
In a closed cycle system the gas is compressed and heat is
supplied by the source at constant pressure,the compressed gas then
expand in the MHD generator.Then it’s pressure and temperature
falls.
After leaving the generator heat is removed from the gas by
cooler,this is the heat rejection stage of the cycle.Finally the gas is
recompressed.
17. LIQUID METAL SYSTEM
When a liquid metal provides the electrical conductivity, it is called a liquid metal MHD
system.
the carrier gas is pressurized and heated by passage through a heat exchanger within
combustion chamber. The hot gas Is then incorporated into the liquid metal usually hot
sodium or lithium to form the working fluid.
The working fluid is introduced into the MHD generator through a nozzle in the
usual ways. The carrier gas then provides the required high direct velocity of the electrical
conductor.
19. Open Cycle System
Working fluid after generating
electrical energy is discharged to the
atmosphere through a stack
Operation of MHD generator is
done directly on combustion products .
Temperature requirement : 2300˚C
to 2700˚C.
More developed.
DIFFER ENCE BETW EEN OPEN
CYCLE A ND CLOSED CYCLE
SY STEM
Closed Cycle System
Working fluid is recycled to the heat
sources and thus is used again.
Helium or argon(with cesium
seeding) is used as the working fluid.
Temperature requirement : about
530˚C.
Less developed.
20. NEED OF MHD
At present a plenty of energy is needed to sustain industrial and
agricultural production, and the existing conventional energy sources
like coal, oil, uranium etc. are not adequate to meet the ever
increasing energy demands. Consequently, efforts have been made
for harnessing energy from several non-conventional energy sources
like Magneto Hydro Dynamics(MHD) System.

22. ADVANTAGES
The conversion efficiency of a MHD system can be around 50% much higher
compared to the most efficient steam plants. Still higher efficiencies are expected in
future, around 60 – 65 %, with the improvements in experience and technology.
Large amount of power is generated.
It has no moving parts, so more reliable.
The closed cycle system produces power, free of pollution.
It has ability to reach the full power level as soon as started.
The size if the plant is considerably smaller than conventional fossil fuel plants.
23. DISADVANTAGES
Suffers from reverse flow (short circuits) of electrons through the conducting
fluids around the ends of the magnetic field.
Needs very large magnets and this is a major expense.
High friction and heat transfer losses.
High operating temperature.
Coal used as fuel poses problem of molten ash which may short circuit the
electrodes. Hence, oil or natural gas are much better fuels for MHDs.
Restriction on use of fuel makes the operation more expensive.
24. OTHER APPLICATIONS
Power generation in space craft.
Hypersonic wind tunnel experiments.
Defense application.
25. FUTURE PROSPECTS
It is estimated that by 2020, almost 70 % of the total electricity generated in
the world will be from MHD generators.
Research and development is widely being done on MHD by different countries
of the world.
Nations involved:
USA
Former USSR
Japan
India
China
Yugoslavia
Australia
Italy
Poland
26. CONCLUSION
The MHD power generation is in advanced stage today and closer to
commercial utilization. Significant progress has been made in development
of all critical components and sub system technologies. Coal burning MHD
combined steam power plant promises significant economic and
environmental advantages compared to other coal burning power generation
technologies. It will not be long before the technological problem of MHD
systems will be overcame and MHD system would transform itself from
non- conventional to conventional energy sources.
