In situ combustion model development and its applications for laboratory studies

Ocalan, Ramazan
Kök, Mustafa Verşan
A one-dimensional in situ combustion model was developed for oil and gas production calculations using a frontal-advance theory combined with mass and energy balance equations and simplified by boundary conditions, limitations and assumptions. The model is run for data from laboratory combustion tube experiments. Model runs for such experiments show that the results are in good agreement with the experimental values for the dry combustion mode, but not for the wet combustion mode where the water injection is high.

In this paper, mechanical models with Newton's Law of impacts are studied. One of the most interesting properties in some of these models is chattering. This phenomenon is understood as the appearance of an infinite number of impacts occurring in a finite time. Conclusion on the presence of chattering is made exclusively by examination of the right hand side of impact models for the first time. Criteria for the sets of initial data which always lead to chattering are established. The Moon-Holmes model is su...
Numerical analysis of a projection-based stabilization method for the natural convection problems
Çıbık, Aytekin Bayram; Kaya Merdan, Songül; Department of Mathematics (2011)
In this thesis, we consider a projection-based stabilization method for solving buoyancy driven flows (natural convection problems). The method consists of adding global stabilization for all scales and then anti-diffusing these effects on the large scales defined by projections into appropriate function spaces. In this way, stabilization acts only on the small scales. We consider two different variations of buoyancy driven flows based on the projection-based stabilization. First, we focus on the steady-sta...
Streamwise oscillations of a cylinder beneath a free surface: Free surface effects on vortex formation modes
Bozkaya, Canan; Mironova, L. A.; Gubanov, O. I. (Elsevier BV, 2011-06-15)
A computational study of a viscous incompressible two-fluid model with an oscillating cylinder is investigated at a Reynolds number of 200 and at a dimensionless displacement amplitude of A = 0.13 and for the dimensionless forcing cylinder oscillation frequency-to-natural vortex shedding frequency ratios, f/f(0) = 1.5, 2.5, 3.5. Specifically, two-dimensional flow past a circular cylinder subject to forced in-line oscillations beneath a free surface is considered. The method is based on a finite volume discr...
Modeling of landfill settlement: Theory
Durmusoglu, E.; Corapcioglu, M.y.; Tuncay, Kağan (null; 2005-12-01)
Theory of a one-dimensional multiphase mathematical model developed to simulate the settlement involving liquid and gas flows in a compressible landfill is presented. Landfill domain is assumed comprised of a deformable solid matrix, a liquid phase, and a gas phase with transient gas generation. After a two-phase model, i.e., liquid and gas phase, was developed, a solid phase was incorporated into the model. A gas generation term was employed as source and sink for solid and gas phases. After governing equa...
Numerical and experimental analysis for comparison of square, cylindrical and plate fin arrays in external flow
İnci, Aykut Barış; Bayer, Özgür; Department of Mechanical Engineering (2018)
Geometrical optimization of square, cylindrical and plate fins for heat transfer augmentation is numerically performed in the external flow. Heat transfer performance of fins with different profiles are compared with same Reynolds number. The relation between the thermal characteristic of fins and boundary conditions like free-stream velocity and heat input are investigated. Experimental studies are performed using manufacturable fins to validate numerical model. Heat transfer correlations are derived in or...
