Project Description (Wind Turbine):

Wind energy is one of the important renewable sources of the energy for 21st century. This project focuses mainly on the turbine blade design for residential wind turbines. The project will consist of design and evaluation of a wind turbine blade system that will achieve a maximum power output for a range of wind conditions.  It is also a proof of concept that shows the economic feasibility of residential wind turbines.  Some of the significant tasks that are to be conducted are summarized as: (1) In order to reduce the loss of the wind flow around the turbine blades, the blade design optimization will be conducted. (2) To increase the efficiency, and to maximize the power, a flow analysis will be conducted over a turbine blade, which will be followed by laboratory wind-tunnel tests as well as computational studies. The experimental analysis will be done to study two different types of designs for Horizontal Axis Wind Turbines. Swept Blades is a concept that is borrowed from Compressor Blades. The effect of Blade sweep on power output will be studied experimentally. The blades will be manufactured by rapid prototyping and tested in the subsonic wind tunnel in USR building. The testing will include the power output and the flow wake velocity and turbulence measurement. A Novel Design of Wind Turbine blade with saw tooth leading edge profile inspired by whale fins will be studied experimentally to study the benefits of the design. The blades will be manufactured by rapid prototyping and tested in the subsonic wind tunnel in USR building. The testing will include the power output and the flow wake velocity and turbulence measurement.


Project Description (Gas Turbine Combustor):

Gas turbine is one of the most common power production plants in the whole world for its easy and fast construction. The simple plant would consist of three main parts: (1) Compressor, (2) Combustion chamber and (3) Turbine and Generator. For material limitations the turbine blades can only withstand temperatures in the range of 500-600oC which is a range that can’t be achieved by normal combustion as it will require a high air to fuel ratio with which the flame is quenched and can’t sustain itself. For this reasons stoichometric combustion is performed than the products are diluted with air to reach the desired temperatures. During this project you will be required:

  • Construct the test rig.
  • Measuring velocity and temperature profiles in the different sections.
  • Draw profiles of temperature and velocities.
  • Check for the uniformity of the temperature at the exit section.
  • Error analysis for the results can be an extra work.
  • Validate this simulation with numerical calculations.


Project Description (Gas Turbine Blade Cooling):

The objective of this project is to prepare experimental set up for two pass square channel and study the heat transfer distribution for constant heated wall (or heated fluid). The main purpose of this experimental study is to report or measure local heat transfer coefficient and associated velocity field in turbulent flow through a two pass square channel with 180 degree. The flow is similar to the flow encounter in the internal cooling passage of modern gas turbine blades. The two flat walls are heated electrically while the other walls insulated. The liquid crystal technique is used to map the local Nusselt number variation. Measurements are done using air flow facilities. The effect of variation of Reynolds number variation ranging from 10000 to 100,000  of 0.7(air) is to be studied. The main focus of this experiment will be on making the complete setup for the experiment for further analysis.


Project Description (Biomass Gasifier):

The rapid depletion of the fossil fuel reservoirs is the prime mover for seeking alternative sources of energy. Nowadays, billions of dollars are spent on renewable energy research. One of the renewable sources of energy is biomass fuels, Industries such as sugar, paper and animal houses  produce large amounts of solid wastes which have significant calorific value, but most of these wastes are either difficult to burn or produce high intensities of harmful emissions, this requires the treatment of these wastes before using to produce energy. A very common way in treating these wastes is by gasification, which is a sequence of processes to convert these solid wastes to combustible gases with higher calorific values and lower harmful emissions when burnt. These processes starts with gasification, reforming, filtering, etc. In this project it is required to study the gasification process and the factors affecting it such as: the gasifying medium used, the gasification temperature and the size of particles used. During this project you will be required to:

  • Define the different parameters controlling the gasification process.
  • Focus on some of these parameters for the current project.
  • Propose and design an experimental set up for the gasification process, including all the materials and measuring devices.
  • Get involved in the ordering process of any relevant materials.
  • Construct the test rig.
  • Complete the experimental measurements.
  • Analyze the results and come out with the conclusions.
  • Submit a final paper for the project.
