This document discusses magneto hydro dynamic (MHD) power generation. MHD power generation uses a conducting fluid, such as ionized gas or liquid metals, that is passed at high velocity through a magnetic field to generate electricity. There are two main types of MHD systems - open cycle systems that use combustion of fuels and seeded inert gas, and closed cycle systems that reuse the working fluid. MHD power generation has advantages like high efficiency and no moving parts, but also faces challenges like material compatibility issues at high temperatures. Overall, MHD power generation represents a new method of electricity production that has potential for improved efficiency but requires further development.
Solar thermal power generation systems use mirrors to collect sunlight and produce steam by solar heat to drive turbines for generating power. This system generates power by rotating turbines like thermal and nuclear power plants, and therefore, is suitable for large-scale power generation.

Magneto hydrodynamics (MHD) (magneto fluid dynamics or hydro magnetic) is the academic discipline which studies the dynamics of electrically conducting fluids. Examples of such fluids include plasmas, liquid metals, and salt water. The word magneto hydro dynamics (MHD) is derived from magneto- meaning magnetic field, and hydro- meaning liquid, and -dynamics meaning movement. The field of MHD was initiated by Hannes Alfvén , for which he received the Nobel Prize in Physics in 1970

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.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers.

3. INTRODUCTION
MHD power generation is a new system of electric power
generation which is said to be of high efficiency and low
pollution.
As its name implies, Magneto Hydro Dynamics (MHD)
concerned with the flow of a conducting fluid in the presence of
magnetic and electric field. The fluid may be gas at elevated
temperatures or liquid metals like sodium or potassium.
Magnetohydrodynamics (MHD) (magneto fluid
dynamics or hydromagnetics) is the study of
the dynamics of electrically conducting fluids.
Examples of such fluids include plasmas, liquid metals,
and salt water or electrolytes.
The field of MHD was initiated by Hannes Alfven, for which
he received the Noble Prize in Physics in 1970.
4. PRINCIPLES OF MHD POWER GENERATION
When an conductor moves across a magnetic field, a
voltage is induced in it which produces an electric current.
This is the principle of the conventional generator where the
conductors consist of copper strips.
In MHD generator, the solid conductors are replaced by a
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.
The principle can be explained as follows: An conductor
moving through a magnetic field experiences a retarding
force as well as an induced electric field and current
5. PRINCIPLE OF MHD POWER GENERATION
The flow direction is right angles to the magnetic fields
direction. An electromotive force (or electric voltage) is
induced in the direction at right angles to both flow and
field directions.
9. PRINCIPLE OF MHD POWER GENERATION
The conducting flow fluid is forced between the plates with a
kinetic energy and pressure differential sufficient to over come
the magnetic induction force.
An ionized gas is employed as the conducting fluid.
Ionization is produced either by thermal means I.e. by an
elevated temperature or by seeding with substance like
cesium or potassium vapors which ionizes at relatively low
temperatures.
The atoms of seed element split off electrons. The presence of
the negatively charged electrons makes the gas an electrical
conductor.
The end view drawing illustrates the construction of the
flow channel.
12. VARIOUS MHD SYSTEMS
The MHD systems are broadly classified into two types.
OPEN CYCLE SYSTEM
CLOSED CYCLE SYSTEM
Seeded inert gas system
Liquid metal system
13. OPEN CYCLE SYSTEM
The fuel used maybe oil through an oil tank or gasified coal
through a coal gasification plant.
The fuel (coal, oil or natural gas) is burnt in the combustor or
combustion chamber.
The hot gases from combustor is then seeded with a small
amount of ionized alkali metal (cesium or potassium) to
increase the electrical conductivity of the gas.
The seed material, generally potassium carbonate is injected
into the combustion chamber, the potassium is then ionized by
the hot combustion gases at temperature of roughly 2300’ c to
2700’c.
14. OPEN CYCLE SYSTEM
To attain such high temperatures, the compressed air is
used to burn the coal in the combustion chamber, must be
adequate to at least 1100’c.
The hot pressurized working fluid living in the combustor
flows through a convergent divergent nozzle. In passing
through the nozzle, the random motion energy of the
molecules in the hot gas is largely converted into directed,
mass of energy. Thus , the gas emerges from the nozzle
and enters the MHD generator unit at a high velocity.
15. CLOSED CYCLE SYSTEM
Two general types of closed cycle MHD generators are
being investigated.
Seeded Inert Gas System
Liquid Metal System
16. SEEDED INERT GAS SYSTEM
In a closed cycle system the carrier gas operates in the form of
Brayton cycle. In a closed cycle system the gas is compressed
and heat is supplied by the source, at essentially constant
pressure, the compressed gas then expands in the MHD
generator, and its pressure and temperature fall.
After leaving this generator heat is removed from the gas by a
cooler, this is the heat rejection stage of the cycle. Finally the
gas is recompressed and returned for reheating.
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.
18. ADVANTAGES
The conversion efficiency of a MHD system can be around
50% much higher compared to the most efficient steam
plants.
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 of the plant is considerably smaller than
conventional fossil fuel plants.
19. LIMITATIONS
The metallic vapours are poor electrical conductors.
High velocities cannot be obtained by expansion in the system
while it is much easier to achieve a high fluid velocity .
employing a gas and a nozzle. This is because the liquids are
practically in compressible.
The overall conversions efficiencies obtainable with liquid
metal system are quite below to that of plasma system.
20. APPLICATIONS
Laser power MHD Generators.
Plasma physics applications.
Power generation in space crafts.
Hypersonic wind tunnel experiments.
Defense applications.
21. PROBLEMS ENCOUNTERED
Seed material potassium attacks insulating materials and make
them conducting.
Electrode materials are chemically eroded by combustion of
gases.
It has been reported that capital costs of MHD plants will be
competitive to conventional steam plants.
Most of the problems are related to material problems caused
by high temperature and highly corrosive and abrasive
environment.
22. CONCLUSION
This power resource play a minor role presently and its
use on a vast scale is yet to be confirmed as it is in its
childhood stage.
These systems permit better fuel utilization. The
reduced fuel consumption would offer additional economic
and special benefits and would also lead to conservation of
energy resources.
The magneto hydro dynamic power generation is one of
the examples of a new unique method of generation of
electricity.
