Dr. Elham Dalir, Post-Doctoral Fellow, Ph.D., Mechanical Engineering

Elham Dalir is a Mitacs postdoctoral research fellow working with Prof. Javad Mostaghimi at the Centre for Advanced Coating Technologies (CACT) and PyroGenesis Canada Inc. Her post-doc project aims to reduce nitrogen oxides (NOx) emissions by thermal plasma torches and use them as a direct replacement for fossil fuel burners in industrial applications. She has received her Ph.D. from CACT in 2021, where she developed a numerical model to simulate the plasma jet oscillations, including the arc dynamics within a commercial direct current (DC) plasma torch. The developed model was then extended to simulate the suspension plasma spraying (SPS) process to understand the fundamentals of the droplets dynamics, heat transfer, and phase change within the process. Her research interests include thermo-fluid sciences, thermal spray technologies, surface engineering, and computational fluid dynamics and heat transfer.

Dr. Mehdi Jadidi, Research Associate, Ph.D., Mechanical Engineering

Dr. Jadidi received his Ph.D. in Mechanical Engineering from Concordia University in 2016 under the supervision of Prof. Dolatabadi. His doctoral study on compressible reactive multiphase flows primarily concerned the understanding of physical phenomena involved in suspension thermal spray processes. Following his Ph.D., he investigated the droplet impact dynamics on solid surfaces at École Polytechnique de Montréal as a post-doctoral fellow. He returned to Concordia University to design and develop a liquid cold spray system. This new machine will be used for coating deposition, manufacturing new metallic components, and repairing worn or damaged components. In 2020, he joined the Dworkin research group at Toronto Metropolitan University, focusing on simulation of combustion processes. He developed novel machine/deep learning models for the low-cost prediction of soot emissions and chemistry in laminar/turbulent flames. He joined CACT in 2022 as a research associate. His main research interests are in the area of thermal spray and surface engineering, cold spray additive manufacturing, CFD, multiphase flows, atomization and sprays, combustion, and machine/deep learning approaches.


Dr. Ram gopal varma Ramaraju, Post-Doctoral Fellow, Ph.D., P.Eng., Mechanical Engineering

Ram obtained his Bachelor, Master and Doctoral degrees in Mechanical Engineering in the years 2004, 2007 and 2012 respectively from JNT University, India. Ram worked as an R&D engineer and designer in Canada and Malaysia from 2012 to 2017. Ram’s earlier research focused on building test setups for evaluating, interfacial heat transfer coefficients, the performance of nano-coolants in an automobile, thermal post-buckling load carrying capacity of structural members, the residual stress in FS welded joints, and friction stir processed joints by the addition of nanoparticles at the joint interface.
