Upon the completion of this session participants will be able to:
- Position the landfill as a man-made system with a significant impact on the environment.
- Discuss which aspects of the landfill as an engineering system are under-researched.
- Describe the general principle of operation of a landfill, name the types of extraction wells used, and their respective conceptual peculiarities; compare qualitatively to hydraulic wells.
- Diﬀerentiate between porous medium ﬂow and continuum ﬂow.
- Identify the disparate ﬂow domains on a drawn schematic of the landﬁll.
- Give ranges of permeability for each porous landﬁll sub-domain.
- Recognize Darcy’s law and turbulent pipe ﬂow equations and all parameters therein.
- Explain why gravity cannot be comprehensively neglected.
- Discuss the relation between medium/boundary permeability and gas ﬂow.
- Explain when the ﬂow within a cross-section might be approximated as planar; explain why this simpliﬁcation signiﬁcantly advance sourability to model the landﬁll system.
- Recognize the radial and spherical ﬂow solutions.
- Examine planar ﬂowvisuals: axisymmetric and non axisymmetric, discuss head loss and radius of inﬂuence.
Engineers or Geoscientists working or interested in the area of ﬂuid dynamics or solid waste management industry(from civil, mechanical, aeronautical, or environmental disciplines)
Canada Research Chair, Thompson Rivers University
Dr. Yana Nec graduated with a B.Sc. degree in aeronautical engineering (Technion, IIT) and worked as a flight test engineer for 4 years (IDF Flight Test Centre). She acquired a M.Sc. degree and PhD in applied mathematics (Technion, IIT), completed a post-doctoral fellowship at the University of British Columbia and eventually took the position of Canada Research Chair at Thompson Rivers University, BC.
Her research harnesses mathematics for the solution of engineering problems in collaboration with local industry. Two current long-term modelling projects are: landfill gas flow (GNH Consulting Ltd., Delta, BC) and river flow subject to dam operation (Golder Associates Ltd., Castlegar, BC). Yana is particularly interested in unclassifiable problems that escape the conventional analysis tools.
