Seminar with Dr Ali Anqi: Reverse Osmosis Desalination Module-Three Dimensional and Transient Analysis

Under the scientific  activity in Engineering college , the Mechanical Engineering Department organized  a seminar  titled “Reverse Osmosis Desalination Module – Three Dimensional, Transient Analysis” presented by Dr. Ali Anqi where faculty and students attended . Below, is scientific content summery of the seminar:

The desalination process using reverse osmosis membrane is used around the globe to produce fresh water. The presentation discussed simulations to examine steady and transient nature of the flow inside a three dimensional desalination module containing cylindrical spacers. Navier-Stokes and mass transport equations are solved to determine the flow and concentration field in the feed channel for Reynolds number of 800. The spiral wound membrane is treated as a functional surface where the solution-diffusion model is applied. The flow and the concentration field are strongly three dimensional and transient in nature. The presenter demonstrated that the momentum mixing induced by the presence of spacers enhances the flux performance of the membrane. It is also shown that transient effects and the secondary flows induced by three dimensional flow transitions are mitigating the concentration polarization and fouling/scaling that occurs along the surface of the membrane.

  The Committee of Higher Studies for Masters and Research at the Department of Electrical Engineering recently held an Orientation Program for new MSc students to mark the beginning of the first semester of the academic year 1446. The event commenced with a welcoming address from the Department Chairman, Dr. AbdulRahman Alayedh, who set a positive tone for the sessions to follow. In the subsequent discussion, Dr. Mohammad Mastoor Alammar, the Coordinator of the Research and Higher Studies Committee, presented crucial information regarding the MSc Program's norms and regulations, which included guidance on the advising committee, course credits, and thesis requirements. The orientation program sought to educate students about the structure of the Master’s Program at both the college and university levels. It also introduced faculty members and their respective specializations, clarified the roles of various units within the academic system, and outlined how the College of Engineering and the Department of Electrical Engineering can support students throughout their academic journey. Additionally, committee member Dr. Javed Khan Bhutto shared his research experiences and discussed future prospects related to the Masters Course. The session concluded with Dr. Mohammad Mastoor Alammar delivering a vote of thanks to all attendees, marking a successful start for the incoming MSc students.
The College of Engineering at King Khalid University achieved the top 200 majors in the world after achieving a rank of 151-200 in the field of chemical engineering. The university also achieved record numbers in the field of electrical and electronics engineering by ranking 401-450 in the world.
  Based on the keenness of the College of Engineering at King Khalid University - represented by the Training Unit - to perfect and develop its outputs and link them to the labor market and for its male and female students to receive the best quality and distinguished learning methods, a number of college students, under the supervision of the head of the Training Unit, Dr. Dhafer Ali Alqahtani, coordinated a field visit. The students visited Al Watania for industries and Tasnee factory  in Riyadh on Wednesday and Thursday, November, 22-23, 2023. The visit aims to acquaint the students with the technologies that fall within their specialization and are used in the Al watania for Industry (its plastic and container manufacturers) and Tasnee (the battery factory), which allowed the college students to learn about the nature of factory work by meeting with the engineers working in the factories. The visit began with a visual presentation of the factories’ parts and components, the developments that took place in them from their inception until today, and what are the security and safety precautions. This visit included a field tour of the factory facilities and their effective contribution to the latest technologies and quality of production in the field of plastics, containers and batteries. An open meeting was also held to discuss and answer students’ inquiries related to factory operations and technologies. At the end of the visit, the college employees expressed their thanks to the representatives of the factories for the warm reception, and the efforts they made to make this visit a success, which comes within the cooperation and constructive interaction between the universities with the governmental and private sectors in the field of industry to link the theoretical reality with the practical and applied, because of its great positive impact and great benefit to its graduates and graduates of the College of Engineering.
