Completed Senior Design Projects
1- Design of Multi-phase flow sensors .
Some details about the project Gas-liquid two-phase flow is important in an increasing number of applications and industries such as Saudi ARAMCO, Schlumberger, Saudi Electric Company. For example, two-phase pressure-drop models are necessary to design the piping systems in the oil and gas industry. In addition, a two-phase flow occurs in heat exchangers, steam generators, chemical reactors, oil transportation, and a lot of process equipment.
Design and operating of two-phase flow measurements sensors are potential tasks for many mechanical engineering graduates, where designing/building in-house sensors are common task where commercial sensors do not work for many applications. Therefore, familiarity with the two-phase flow measurements sensors consider to be a valuable experience for the students during their senior project period.
The proposed project includes designing a two-phase flow measurement sensor, sensor manufacturing, sensor testing and statistical data analysis of the sensor output.

2- Design of air-lift pump under multi-phase flow conditions.
Some details about the project
Air lift pump is a device for raising liquids or mixtures of liquids and solids through a vertical pipe, partially submerged in the liquid, by means of compressed air introduced into the pipe near the lower end. The air then returns up in a discharge pipe carrying the liquid with it. The pump works by "aerating" the liquid in the discharge pipe. The added air lowers the specific gravity of the fluid mixture. Since it is lighter than the surrounding liquid, it is pushed upwards. Recently, airlift pumps are finding increasing use where pump reliability and low maintenance are required, and when a compressed air is readily available as a source of a renewable energy for water pumping applications. Also, airlift pumps can be used for conveying slurries in mining and sludge removal in sewage treatment plants.The proposed project includes designing an airlift pump and optimizes the design of the air-injector for the pump best performance, in addition to, performing an experimental validation to the developed design in the fluid mechanics laboratory.
