Dr. Shidvash Vakilipour is an Associate Professor of Aerospace Engineering in the College of Interdisciplinary of Science and Technology at the University of Tehran and a member of the Canadian Society of Mechanical Engineers. He is a proud graduate from Sharif University of Technology and holds his PhD from there. His PhD thesis was focused on developing an All-speed Control Volume Finite Element Method (CVFEM) for compressible gaseous micro-flows. He joined a post-doc program at the University of Manitoba in April 2010. In post-doc, he developed a fully-coupled cell-centered finite volume method for computation of heat and mass transfer in unsteady two-phase flows with condensation, absorption, or evaporation. His main areas of research are developing Finite Volume Methodologies for Computational Fluid Dynamics and Heat Transfer to simulate:
 
  • Falling film and two-phase flows
  • Unsteady condensation, absorption, and evaporation
  • Flow and thermal fields around moving oscillating bodies
  • All-speed flows
  • Desalination with falling films

Scott Ormiston


Professor at the University of Manitoba, CA, P.Eng
 
Dr. Ormiston is a Mechanical Engineering professor at the University of Manitoba. His research is focused on CFD (Computational Fluid Dynamics) with heat and mass transfer applications. New methods have been developed to model film condensation from a mixture of a vapour and a non-condensing gas. Example application areas are models for plate and shell-and-tube heat exchangers used in the power generation, refrigeration, and chemical processing industries. New FVM-based fully coupled solution approaches have been developed for problems with strong interactions of heat and mass transfer.
Models have been developed for:
  • Two-phase flow of film condensation from a gas mixture (non-condensing gas and vapour or binary vapour)
  • Two-phase flow of falling film absorption
  • Laminar and turbulent flow in tube bundles and corrugated plate channels
  • Turbulent mixed-convection flow in thyristor valve halls
  • Below-grade heat losses from concrete slab building foundations with in-floor heating
  • Solar mass wall systems
  • Branching single-phase flow
  • Falling films with condensation, absorption, or evaporation
  • Bubbly flow in a vertical pipe

Fault Detection in a Steam Turbine Using Engine Condition Trend Monitoring (ECTM) Based on Machine Learning 

 
Monitoring the health status of rotating machines, especially steam turbines, is an important task in order to ensure reliability in industrial processes. One of the important defects in steam turbines is the phenomenon of corrosion and erosion of its blades due to the impact of water droplets, which seriously affects their useful life. In this research, by using the combination of two methods, model-oriented and data-oriented, which are based on artificial neural networks, the momentary detection of the presence of water droplets and its formation process on the low pressure blades of the turbine is investigated.
