Dr. Saleem Anwar Khan, a Professor in the Department of Mechanical Engineering at Aligarh Muslim University (AMU), holds a doctoral degree from Aligarh Muslim University, Aligarh. His research expertise lies in Computational Fluid Dynamics and Heat Transfer.
Throughout his academic journey, Dr. Khan has imparted knowledge to students across various levels, including undergraduate, graduate, and postgraduate courses. His teaching portfolio encompasses subjects such as Transport Phenomena, Unit Operations, Heat & Mass Transfer, Fluid Mechanics, Industrial Engineering, and Autonomous Robots.
Beyond the classroom, Dr. Khan actively engages with students in extra-curricular activities and serves as the Assistant Training & Placement Officer for ZHCET. His leadership extends to being the Campus Director for the prestigious ‘Hult Prize (USA) 2018’ initiative. He is also a member of the Professional Development and Scholarship Subcommittees for the Marine Technology Society, USA. Additionally, he collaborated with faculty members and administrators to establish a new master’s program in Robotics and Automation within the Department of Mechanical Engineering.
Currently, Dr. Khan oversees a groundbreaking project focused on Autonomous Underwater Vehicles (AUVs). Under his guidance, students from diverse streams—Mechanical, Electrical, Electronics, and Computer Science—collaborate to design and fabricate a low-cost, long-range Underwater Bot capable of fully autonomous operations even in deep waters. His contributions extend to securing four granted patents, with three related explicitly to AUVs.
Recognized for his outstanding work, Dr. Khan received the ‘Bharat Vikas Award-2017’ for his contributions to Autonomous Underwater Vehicles. Recently, he was honored with the Outstanding Scientist Award at the International Scientist Awards on Engineering, Science, and Medicine held in Coimbatore in June 2022.
His research interests span a wide spectrum, including AUVs, Biomimetic Fish Underwater Robots, Heat and Mass Transfer, Fluid Flow, Computational Fluid Dynamics, and Micro-Fluidics. Dr. Khan has also authored books and contributed over forty research articles to internationally acclaimed journals and book chapters.
- Vortex Shedding Suppression of Vibrating Square Cylinder in Mixed Convection Regime In the present work, vortex shedding suppression of a vibrating square cylinder is numerically studied at Reynolds number, Re ¼ 100, and Prandtl number, Pr ¼ 7.1, in a mixed convection regime. Navier–Stokes equations with Boussinesq approximation are solved using a finite difference method by transforming it into a body-fitted coordinate system. The relationship between fluid flow and a vibrating square cylinder is captured using an Arbitrary Lagrangian Euler method. Numerical simulations are conducted for reduced velocities, Ured ¼ 3–8 keeping the reduced mass (Mred) ¼ 2 and damping coefficient, n0 ¼ 0. The role of baroclinic vorticity is studied on the vortex shedding suppression for an elastically mounted free vibrating heated square cylinder. The critical Richardson number, Ric (Richardson number at which vortex shedding becomes suppressed) is determined by increasing the Richardson number (Ri) and observing the vortex shedding pattern. For every Ured ¼ 3–8, a Ric is obtained. It is found that critical Richardson number (Ric) for the lock-in regime (Ured ¼ 6) is 0.395 whereas for the initial branch (Ured ¼ 3) and lower branch (Ured ¼ 8) it is 0.17 and 0.18, respectively. Baroclinic vorticity generation for the lock-in regime, initial branch, and lower branch is also investigated comprehensively. The Ric for the initial and lower branch is close to Ric for the stationary cylinder. The Ric for the stationary cylinder (SC) is 0.165.
- A comprehensive investigation of vortex-induced vibrations and flow-induced rotation of an elliptic cylinder This work finds its motivation in heat exchanger design and flow control. Flow-induced vibration is studied numerically for combined vortex-induced vibrations and vortex-induced rotations of a horizontally positioned elliptic cylinder. The aspect ratio is taken as 2, and the value of reduced velocities (Ured) considered for the present simulation is between 2 and 12. The body can have to and fro motions in a transverse (y) direction, in-line (x) direction as well as in azimuthal (h) direction, which provides three degrees of freedom (DOF) to the body. It is found that for one-DOF (y-direction only) and two-DOF (y and x directions) cases, lock-in regions are the same while it is wider for the case of the three-DOF system. With the rotational DOF, y-directional motion is amplified and when it is compared with the one-DOF and two-DOF cases, difference in peak amplitude is about 30%. The rotational response reaches a maximum value within the synchronization regime, and the frequency behavior of rotational and transverse oscillations is showing the same characteristics. The phase difference is plotted to check their synchronization with respective forces and moments. For all DOFs and Ured, synchronized or desynchronized regions, 2S mode of vortex shedding was observed. For one-DOF and two-DOF cases, the transverse vibrational frequency ratio (fy=fn) becomes equal to unity for the range 3:75 Ured 5. For three-DOF, fy=fn and rotational frequency ratio (fR=fnÞ become close to the unity for 3:75 Ured 6. The three-DOF system shows smaller wake width and vortex formation length whereas the vortex strength is maximum.
