Associate Professor, Department of Mechanical Engineering

Dr. Nader Vahdati is currently an Associate Professor of Mechanical Engineering Department at Khalifa University. Before the merger of Petroleum Institute with Khalifa University, Dr. Vahdati served as a Deputy Chair, and Department Chair of the Mechanical Engineering Department from 2010 till 2017. Prior to the Khalifa University/Petroleum Institute, he was with the Nanyang Technological University (NTU) in Singapore from 2001 to 2010. While at NTU, he did his research on hard disk drives, MR-fluid dampers and rotary brakes, heath or condition monitoring systems and integrated sensors, and semi-active/active hydraulic engine mounts. He also held the position of Director of Mechanical and Aerospace Engineering (MAE) Part-time Program for 6 years. Prior to NTU, Dr. Vahdati spent 12 years in industry (Lord Corporation) and he held the position of staff engineer/Application Analytics Group Supervisor. During his tenure at Lord, he worked on active/semi-active suspension system, involving sensors, actuators, and controllers used for automotive and aerospace applications. He received his Ph.D. degree from the University of California, Davis, in System Dynamics and Controls.

Dr. Vahdati's main research interests are fiber optics based corrosion detection sensors, scale detection sensors, gas hydrate detection sensors, active/semi-active vibration and noise control, controllable fluids and devices, and smart materials and devices. He is Faculty Lab Coordinator for Asset Integrity Management (AIM) Lab.

    Recent Research Projects

    • Pipeline System Integrity Management (PSIM) Research Project, (Sponsor: ADNOC/KU, Principal Investigator: Nader Vahdati, 2015-2020, funding: $7 Million dollars. A joint project between KU, UMD and ADNOC. The focus of PSIM research project is on Fiber optics based corrosion sensors for detection of external and internal corrosion of oil and gas pipelines, fundamentals of corrosion, and Prognosis and Health Monitoring Research.

      

    • Nonlinear Hydraulic Engine Mounts (Sponsor: KU, Principal Investigator: Nader Vahdati) and Electronic Hydraulic Engine Mounts (Sponsor:  KU, Principal Investigator: Nader Vahdati)

    In the above two research projects, research is ongoing to develop hydraulic engine mount designs that are sensitive to deflection (decoupler plate is removed and replaced with a new design) and fluid is removed but hydraulic engine mount behavior is retained.

    • Fatigue Crack Growth Analysis of Aerospace Components. Sponsor: Republic of Singapore Air Force and DSTA, S$199,448, Principal Investigator: Nader Vahdati, to perform fatigue crack growth analysis and experiments on the F-5 and F-16 lug components. This project was a joint project between US Air Force Academy (USAFA), Republic of Singapore Air Force, DSTA, and NTU. 2009-2011.
    • Smart suspension systems to mitigate shock of operating small form factor HDDs, (Sponsor: Seagate, Principal Investigator: Nader Vahdati), Funding: S$180,000. The purpose of this research project was to develop smart suspension systems to mitigate shock of operating small form factor HDDs subject to severe shocks. 2006-2010.

    • Controllable Dampers for Wheeled Military Vehicles, (Sponsor: Singapore Technology Kinetics, Principal Investigator: Nader Vahdati). Funding: S$300,000. The purpose of this research project was to develop Magneto-rheological controllable dampers for wheeled military vehicles such that it has a very smooth ride over rough bumps yet has a good handling. 2004-2010.
