Desalination is a process of converting sea water into fresh water which can be used by people for
their daily uses. Man has always looked for oceans to enjoy the benefit of water. Some of the early discoveries
of it is by Aristotle and others. The people of that time came up with distillation and filtration using soil deposits
to obtain drinking water from the sea. After that many methods came of desalination like reverse osmosis, etc.
and were used and thermal energy method was found cheapest and hence we came to know that we can use this
processing a portable desalination plant. The potential of thermal energy is huge all around the world and it
has been used in various processes all around. It is used for desalination process which will cure the problem of
scarcity of water in the world and mostly in the water drought regions in India. This project is focused on
making fresh water from sea water in the cheapest price available and in very small setup.

Critical worldwide concern
Previously developing nation’s issues
Now Global Crisis
Quantity and Quality Issues
From Surplus to Limited
The problem of the scarcity of fresh water is incredibly pressing and constantly increasing due to population growth and consumption. Investing in the development of sustainable systems for brackish and sea water desalination remains one of the key points on which it is worthwhile to concentrate our efforts to solve this problem. Moreover, the need of replacing fossil fuels in many areas of human activities is strongly felt, in particular for the primary resource fresh water, that must be regenerated, where the natural availability is not present or it has been depleted. The technologies for the production of desalinated water, normally make use of electrical (reverse osmosis) or thermal energy (distillation using gas/oils combustion) from fossil sources. The technology presented in this paper has been named “Solar Desalination Geoassisted Continuous”, an innovative system for salty and brackish water desalination, covered by an Italian patent, made-up and registered by Stefano Farné and Vito Lavanga, almost totally exploiting solar power and capable of producing distilled water with very low running costs compared to current technologies. The SDGC system effectively obtains water evaporation and is able to function only by integrating losses due to the not perfect thermal insulation of the materials.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Main Problem
Water Problem
Water scarcity is the
lack of fresh water
resources to meet water
demand. It affects every
continent and was
listed in 2019 by the
World Economic Forum
as one of the largest
global risks in terms of
potential impact over
the next decade .
Most scientists now believe
that carbon dioxide
concentrations in the
atmosphere are rapidly
increasing, and that
emissions from the burning
of fossil fuels is a principal
cause. Thus, it is probable
that this will affect the
climate and lead to global
warming. Also Fossil fuels is
finite source of energy.
6. Objective
s• Desalinating water to overcome fresh
water crisis.
• Using sustainable and
renewable energy instead of
fossil fuel.
6
• Reduce the production cost.
• Using clean energy to reduce
pollution.
7. Renewable
Energy
Energy obtained from natural
energy occurring in the
immediate
Environment.
Infinite source of energy, clean
and cheap.
Has a lot of types such as:
Solar, Wind, Hydropower,
Geothermal and Tidal energy.

A solar energy system has no moving
parts, which means less risk to damage
and less maintenance.
Solar energy systems provide more
predictable energy outputs.
Relatively silent in operation, fast
installation
Egypt received about 2400-2800 kWh/m2 per year
as direct normal irradiance.
9. Understanding
Osmosis.
Osmosis is the tendency of water to flow
from a hypotonic solution (low
substances) to hypertonic solution (higher
of dissolved substances) across a
membrane.

10. What is Reverse
Osmosis, “RO”?
Reverse Osmosis is a technology that is
used
to remove a large majority of
pushing the water under pressure through
semipermeable membrane.
10
Reverse Osmosis removes: More than 99%
of dissolved salts(ions), Dust Particles,
Colloids Organics, Bacteria, Pyrogens. And
many more.
11. Concentrating solar thermal (CST) systems
• CST technologies use different mirror configurations to
concentrate the sun’s light energy onto a receiver and convert it
steam with high pressure.
• In a CST system, the solar-generated heat replaces the burning of

38. Future Recommendations 38
Make sure that there are no any air gaps
between aluminum sheet because when
temperature increase the air got hotter and
cause increase in pressure which cause failure
of tube glass.
Using aluminum sheet inside
evacuated tube enhance radiation
absorption because it increases
collecting area..
It is preferred to use curved mirror
instead of mirror strips as it have
noticed increase in efficiency.
Consider in design that you have
movable mechanism to fix the
receiver tube in the focal because
you might find mismatch in focal
between theoretical and actual
design.
It is better to follow
meteorological authority to be
sure of sunny hours and rainy
days..
Be careful while dealing with hot
surfaces and use safety tools to
avoid injury.
