Within the activities of the scientific and cultural activity of the second semester of the Department of Chemical Engineering at the University of Technology for the academic year 2017-2018, the student of the Master Elaf Khalid lecture entitled:
Improvement of Dray Raduction for Water Flow in Pipe Based Nano Fluid
"Reducing the obstruction of fluid flow in pipes by adding nanomaterials"
Al Khwarizmi Hall in the department in the presence of the Head of Chemical Engineering Department. Jamal Mouna Ali Al-Rubaie and Scientific Assistants Dr.D. Khalid Ajmi Saker and Al-Adari A.D. Walaa Abdulhadi Nuri and a number of heads of branches and teachers and employees and students of the university.
In this research, the student showed that several methods were used to reduce the high cost of energy used to transport fluids in pipelines. , Where recent studies have demonstrated the effect of nanotubes as a reduction in fluid flow. The aim of this study is to understand how the presence of solids or nanoparticles in liquids can reduce the problems of friction losses in pipes. This study investigated the effect of nanoparticles as mitigating factors for energy losses resulting from water transfer in pipelines. Where nanotubes are added at low concentrations such as parts per million to the solution. These small quantities played a dominant role in reducing disturbance and causing a significant reduction in friction losses. The tested water samples were selected, and nanotubes used for water and nanoparticles were used in five different concentrations (50-250 ppm) The experimental system consists of four different types of pipes (a 29.6 mm steel pipe, a 18.3 mm steel tube, a 29.6 mm glass tube, a 29.6 mm L pipe), water pumping at different flow rates (1.0 to 8.0) ) M3 / h for each type of pipe and at room temperature (35 ± 1) o. In addition, the effect of the type of nanoparticles such as silica SiO2 and TiO2 was also studied for comparison purposes.
The Registration and the Documentation Divisions of the Department of Petroleum Technology at the University of Technology held a seminar to present the new electronic system, the seminar was hold on the conference hall with the presence of the head of the department Prof.Dr.Aqeel Shaker, both scientific and administrative deputies Asst.Prof.Dr.Adeel Shareef and Asst.Prof.Dr.Raid Naeem, head of the division Asst.Prof.Dr.Ahmed Abdul-Ridha and a number of department staff.
The Director of the Registration Division Saif Emad Abdul Razzaq showed the importance of the new system by searching the files of students at high speed and knowing the curriculum vitae of all students at a certain stage and certain academic year determined by the user. The program also includes statistics for the accepted students for all academic years, gender of the student (male and female), the number of applicants, the names and the names of the defendants, the disqualified, and the successful since the establishment of the Department until this year.
The system also includes an electronic record and the installation of the administrative track of the document, the ability to make statistics for documents and complete within one month only or a period that can be determined by the employee.
Within the scientific and cultural activities of the second semester of the Chemical Engineering Department at the University of Technology for the academic year 2017-2018, the master student Zainab Abdul Amir present a seminar entitled " Static and Dynamic Study of Nitrate Anion Adsorption from Aqueous Solution using Different Adsorbents" on Al-khawarizmi Hall in the presence of the head of department Asst.Prof.Dr.Jamal Mana, both scientific and administrative deputies Asst.Prof.Dr.Khalid Ajmi and Asst.Prof.Dr.Walaa Abdul Al-Hadi and number of faculty.
The student explained in this study the assimilation process of three phases in this work. The experimental work was carried out in the Perspex column with a diameter of 0.092 m and a height of 2 m using the Teflon plate as a distributor containing 42 circular derricks and a circular hole of liquid that was placed at the bottom of the column to study the effect of gas speed, Solid material on both residual gas, liquid and solids, diameter of bubbles and speed of bubbles.
Kerosene and water were used as continuous phases, and air was used as a dispersion phase. The glass beads were used in the diameter of 0.0038 m, the density of 2247 kg / m3, the helping factor from the kerosene treatment reactor located in the sump filter at 0.0025 m, and the density of 2070 kg / m3 as a solid phase. And pressure readings for different speeds of gas and liquid. Surface velocities of liquid and gas are (0.025 m / s - 0.65 m / s) and 0.005 m / s - 0.04 m / s respectively. Various operating variables include speed of gas and liquid, liquid type and particle dimensions. The CFD results were verified from the dynamic characteristics obtained from the simulation with the experimental results using anisys flonte 16.0. The yulian multi-stage particle flow approach was used to predict the overall performance of gas and liquid gas.
