This study presents a computational analysis of a device that mimics dust devils in a controlled environment in order to explore its capacity as an energy conversion apparatus in solar energy applications. Concept is built upon the buoyancy effect over a heated plate surrounded by stationary vertical thin plates (vanes), which cause swirl in the raising air. The novelty of the paper is that it is the first parametric study that investigates effects of vane width, vane height, number of vanes, and vane angle on the vertical flow rate of the proposed device. It is found that (i) the optimal vane width is 1.4R, (ii) reduction in spacing between the vanes improves vertical flow strength, (iii) minimum vane height is 1.4R, and (iv) high vane angles increase swirl and hence vortex stability to yield better torque production opportunities with the high air speeds away from the vertical centerline.

Computational analysis of a solar vortex
Mohiuddin, Abdullah; Uzgören, Eray; Sustainable Environment and Energy Systems (2015-3)
This thesis investigates power generation opportunities by considering computational analysis of an experimental setup which is initially proposed to mimic dust devils in a controlled environment. The concept relies on buoyancy effect over a heated plate surrounded by vertical thin plates or vanes. Once the heated air starts rising, vertical vanes help surrounding air to flow inwards in a direction tangential to the vortex core to introduce swirl to the flow. Present study focuses on the computational fluid...
Numerical investigation of circulating fluidized bed riser hydrodynamics for concentrating solar thermal receiver applications
Bilyaz, Serhat; Tarı, İlker; Department of Mechanical Engineering (2015)
Various heat transfer fluids and thermal storage materials are considered for concentrating solar power systems to improve the storage capability of the system which compensates the fluctuating behavior of the solar resources. Solid particles can be a good alternative since they have high sensible heat capacity. In addition, they are cheap, environmentally benign and chemically and mechanically stable at high temperatures. In this thesis, hydrodynamics of circulating fluidized bed solar receiver was numeric...
Simulation of solar thermal applicatıon in a cement plant
Salehian, Shadi; Tarı, İlker; Department of Mechanical Engineering (2020)
This study presents solar thermal application in the most energy consuming units of a cement plant located in Gaziantep, Turkey. Cement industry is the most important energy intensive and the second largest contributor to anthropogenic greenhouse gas emissions in the world which accounts for 5-6% of global CO2 emissions. Both material and energy flows are analyzed in the system for a conventional cement industry and a solar integrated one taking the most energy-efficient innovations into account. The whole ...
NUMERICAL INVESTIGATION OF BUBBLING FLUIDIZED BED TO BE USED AS THERMAL ENERGY STORAGE INTEGRATED TO HIGH-TEMPERATURE CONCENTRATED SOLAR POWER
HİÇDURMAZ, SERDAR; Tarı, İlker (Begell House, 2018-01-01)
A thermal energy storage unit designed to be used in a solid particle concentrated solar energy system is analyzed with the help of ANSYS Fluent 17.0. Hydrodynamics of the bubbling fluidized sand bed of 0.28 m × 1 m × 0.025 m dimensions to be used as a direct contact heat exchanger is modeled and validated. Geldart B-type particles with diameter of 275 micrometers and density of 2500 kg/m3 are used in modeling of bubbling fluidized sand bed. A Syamlal−O'Brien drag model with restitution coefficient of 0.99 ...
Numerical methodology for feasibility analysis of ground source heat pumps
Gamage, Kumudu Janani; Uzgören, Eray; Sustainable Environment and Energy Systems (2014-8)
Ground source heat pump (GSHP) systems provide an alternative energy source for residential and commercial space heating and cooling applications by utilizing the favorable temperature profile at a certain depth under the ground surface. GSHP’s aftereffects on the ground temperature profile need to be considered for estimating the economical breakeven point. The present study develops a new semi-analytical model to analyze the short term response of the ground heat exchangers by accounting the depth depende...
