Radiative heat transfer in the discrete element method using distance based approximations
Johnson, Evan F.; Tarı, İlker; Baker, Derek Keıth (2021-03-01)
A model to estimate radiative heat transfer in particle beds is developed for use in the Discrete Element Method (DEM). Monte Carlo ray tracing simulations are run to find the Radiation Distribution Factor (RDF) between pa...
A Monte Carlo method to solve for radiative effective thermal conductivity for particle beds of various solid fractions and emissivities
Johnson, Evan; Tarı, İlker; Baker, Derek Keıth (Elsevier BV, 2020-07-01)
A method is described to find the effective thermal conductivity due to radiation (k(rad)) for groups of particles at packed and less than packed states. Unlike most previous studies, the method does not rely on the assump...
Solar-thermal driven drying technologies for large-scale industrial applications: State of the art, gaps, and opportunities
Kamfa, In'am; Fluch, Juergen; Bartali, Ruben; Baker, Derek Keıth (2020-07-01)
Research and Innovation (R&I) on Large-scale Industrial Solar-thermal driven Drying technologies (LISDs) is one of the strategies required to transition to a low-carbon energy future. The objective for this work is to guid...
Modeling, transient simulations and parametric studies of parabolic trough collectors with thermal energy storage
Akba, Tufan; Baker, Derek Keıth; Güvenç Yazıcıoğlu, Almıla (Elsevier BV, 2020-03-15)
For investigating the system response of parabolic trough collector heat generating system, a plant with parabolic trough collector field and two-tank molten salt thermal energy storage model with component-level control a...
An investigation of optimum PV and wind energy system capacities for alternate short and long-term energy storage sizing methodologies
Al-Ghussain, Loiy; Taylan, Onur; Baker, Derek Keıth (Wiley, 2019-01-01)
The goal of this study is to find the optimal sizes of renewable energy systems (RES) based on photovoltaic (PV) and/or wind systems for three energy storage system (ESS) scenarios in a micro-grid; (1) with pumped hydro st...
Development of view factor correlations for modeling thermal radiation in solid particle solar receivers using CFD-DEM
Johnson, Evan; Baker, Derek Keıth; Tarı, İlker (null; 2018-10-05)
Radiation heat transfer must be modeled when designing any high temperature solid particle solar receiver or particle-fluid heat exchanger, but computationally efficient radiation models are not currently available in coup...
Sizing of Photovoltaic-Wind-Battery Hybrid System for a Mediterranean Island Community Based on Estimated and Measured Meteorological Data
Sadati, S. M. Sajed; Jahani, Elham; Taylan, Onur; Baker, Derek Keıth (2018-02-01)
Deploying renewable energy systems (RES) to supply electricity faces many challenges related to cost and the variability of the renewable resources. One possible solution to these challenges is to hybridize RES with conven...
Technoeconomic and exergy analysis of a solar geothermal hybrid electric power plant using a novel combined cycle
Bonyadi, Nima; Johnson, Evan; Baker, Derek Keıth (2018-01-15)
A novel Solar Geothermal Hybrid Electric Power Plant (SGHEPP) based on the hybridization of an existing binary Geothermal Electric Power Plant by adding a solar-powered steam-Rankine topping cycle is proposed. The proposed...
Numerical Analysis of Phase Change Material Characteristics Used in a Thermal Energy Storage Device
Bonyadi, Nima; Somek, Suleyman Kazim; Ozalevli, Cemil Cihan; Baker, Derek Keıth; Tarı, İlker (2018-01-01)
In this study, a numerical analysis is performed to investigate the freezing process of phase change materials (PCM) in a predesigned thermal energy storage (TES) device. This TES device is integrated with a milk storage c...
NUMERICAL COMPARISON AND SIZING OF SENSIBLE AND LATENT THERMAL ENERGY STORAGE FOR COMPRESSED AIR ENERGY STORAGE SYSTEMS
Kaya, Mine; Tarı, İlker; Baker, Derek Keıth (2016-11-17)
Compressed Air Energy Storage is a promising large-scale storage system in part because of its high power rating during discharge. But it is not the cleanest way of storing energy due to the necessity of an external heat s...
