A Theoretical study has been conducted on the influence of Semi-tube

orientation on combined free and forced laminar convection heat transfer

where the Semi-tube heated with constant surface temperature. The

theoretical study was done in the thermal entrance region and

hydraulically fully developed region.

Theoretically the governing equations for a flow through an inclined

Semi-tube were reduced to four, which are continuity equation, radial and

tangential momentum equations, axial momentum equation and vorticity

equation in which the variables where the temperature, vorticity, stream

function and axial velocity. These equations were reduced to

dimensionless equations in which Grashof, Prandtl, Reynolds and

Rayleigh numbers were presented.

ABSTRACT :

The Iraqi provinces, particularly, the city of Anbar as a large state with

wide areas for deserts and inhabited by several thousand people, suffer

one of the most important impacts which is the deterioration air quality

due to air pollution caused by dust storms. The stop of the working of

afforestation and the establishment of green belts and enlargement of

the residence apartments led to increase the effect of the dust on the

environment. The storms which happen several times annually cause

damages on different fields; economic, medical, environment and even

the view of the city. To overcome this dilemma, too much costs are

required to be spent for cleaning the city, streets, and buildings. This

dilemma motivated us to do this project in order to find effective and

economic solution to reduce the dangerous might threaten the life of a

huge number of patients. A new and inexpensive design has been

developed and fabricated in this project to absorb the dust from a room

to protect the life of the patients avoiding devolve them to the

emergency room at the hospitals. The operation of air cleaning from the

dust particles was carried out by using very fine air filter fixed in an air

washer device but without using water. More details are explained

thoroughly in its place in this project. During the first semester, only the

device design and fabrication were performed. In addition, the test room

(lab) was prepared to be govern and not leakage might take place to

ensure the precise estimations

Abstract

The beam is subjected to forced vibrations that can be defined as

displacement of beams from equilibrium position and left free, it will vibrate

at a frequency based on the constants of inertia and inertia. What helps to

sustain the vibration is the energy stored in the vibrator at the beginning of

the vibratory movement but because of the friction resistance that exists no

matter how small the amplitude of the vibration will gradually diminish with

Time until the vibrator stops vibrating. In order to maintain continuous

vibrations, the vibrator must continuously be supplied with energy to

overcome the impact of friction. If the method is to provide the vibrator with

energy in the form of a periodic external force, then the vibrator is said to be

in a "forced vibration" or forced state.

The aim of the project was to conduct practical experiments on forced

vibration in the beams previous research found that the vibration of the

beams increases as the frequency of the external forces approaches the

normal frequency (resonance) and the vibration increases frequency away

from normal frequency.

ABSTRACT

This study suggests an experimental performance study of a manufactured solar

Parabolic Trough Collector (PTC). A study of the trough thermal analysis is

necessary to evaluate the performance of a PTC. The study will take into

account different parameters : ( mass flowrate of working fluid , different solar

radiation ) The results of the research studied in literature showed that the

efficiency of PTC decreases for various mass flow rates and HTF, as the inlet

fluid temperature increases. This is because the radiation losses increased as the

collector temperature increases.

Abstract

This thesis presents the design of Mini CNC Machine. This machine has 2axes, namely the

Xand Y axis. Mini CNC machine is a small CNC machine that can operate like a normal

CNC machine with a limited area of the machining. The objectives of this project are to

develop the mini CNC Machine and to develop the software to control the machine. This

thesis describes the development of the machine and the criteria needed to build the machine.

The Mini CNC Machine is initially sketched by referring to the criteria that was decided. The

criteria are the travel path length, type of linear motion, type of linear drive, motor and

controller, and type of material that used. This machine’s travel on the X axis is 15cm and Y

axis is 15cm. The linear motion was used is a round linear rail and the linear drive used was

a sliding element, lead nuts and lead screws. The motor used is a stepper motor with

specification 2.1V and 3.0A. The frame material used is aluminium. This material is used

because it is light in weight, easy to handle and machine and it is rust proof. The design was

sketched using SolidWork software. For the next step is developing the wiring for motor and

develop the program to control the stepper motor. The ULN 2803 is used to convert the

signal from parallel part to specific winding energizing sequences to step the motor. The

Visual Basic software is used to program the motor movemen

ABSTRACT

Today in the world, there is a lot of demand for energy that can benefit our daily lives.

There are many resources available for energy generation, such as coal, natural gas and

nuclear. Among these resources, coal has been commonly used in thermal power plants

about 41% of the worldwide energy supply. However, these kinds of fuels are also cause a

large pollution to our environment. So in view of the crisis of current situation, there is a

need to explore and use the available alternative or clean resources.

This project focuses on studying and trying to design a hydrogen gas wet cell. This

hydrogen or HHO gas generator uses the principle of electrolysis to split water into its two

molecules, hydrogen and oxygen, in gas form, this gas is also identified brown gas. It is

actually an electrolysis unit having high grade stainless as electrodes and mixture of water

and suitable ionic solution KOH as electrolyte.

This project are going to conduct the experiments to investigate the effects of

electrolysis process variables such as current, voltage, amount of the electrolyte used in the

electrolysis unit etc., on the content of hydrogen gas produced.

ABSTRACT

In 1919, the physicist Albert Betz showed that for a hypothetical ideal wind-energy

extraction machine, the fundamental laws of conservation of mass and energy allowed no

more than 16/27 (59.3%) of the kinetic energy of the wind to be captured. This Betz' law

limit can be approached by modern turbine designs which may reach 70 to 80% of this

theoretical limit.

In addition to aerodynamic design of the blades, design of a complete wind power system

must also address design of the hub, controls, generator, supporting structure and foundation.

Further design questions arise when integrating wind turbines into electrical power grids.

order to find an effective and economic solution to reduce the dangerous

might threaten the life of a huge number of patients and cover the city with a

dusty colour by dust. The idea of water spray from a very high height tails in

Haj and Umra places in the kingdom of Saudi Arabic is developed in order to

find an appropriate technique for settling the dust from air in the

environment. This inexpensive design has been developed and fabricated in

this project for this demand. The operation of air cleaning from the dust

particles was carried out by using high pressure water pumps for forcing the

water through eight nozzles. More details are explained thoroughly in its place

in this project. During the first semester, only the device designing and

fabrication were performed. In addition, the test room (lab) was prepared to

be tight and no leakage might take place to ensure the precise estimations.
