51 Sutherland, James ClaytonPrediction of oxy-coal flame stand-off using high-fidelity thermochemical models and the one-dimensional turbulence modelAn Eulerian one-dimensional turbulence (ODT) model is applied to simulate oxy-coal combustion, with specific aim at predicting flame stand-o distances. Detailed gas-phase chemical kinetics based on the GRI3.0 mechanism are utilized. A high-fidelity model for devolatilization is considered that predi...2014-01-01
52 Sutherland, James ClaytonAdvanced regression methods for combustion modelling using principal componentsModelling the physics of combustion remains a challenge due to a large range of temporal and physical scales which are important in these systems. Detailed chemical kinetic mechanisms are used to describe the chemistry involved in the combustion process yielding highly coupled partial differential e...2014-01-01
53 Sutherland, James ClaytonA comparison of various models in predicting ignition delay in single-particle coal combustionIn this paper, individual coal particle combustion under laminar conditions is simulated using models with various levels of complexity for the particle and gas phase chemical kinetics. The mass, momentum and energy governing equations are fully coupled between the particle and the gas phase. In the...2014-01-01
54 Eddings, Eric G.The potential of on-line optical flow measurement in the control and monitoring of pilot-scale oxy-coal flamesDigital image processing techniques oer a wide array of tools capable of extracting apparent displacement or velocity information from sequences of images of moving objects. Optical flow algorithms have been widely used in areas such as traffic monitoring and surveillance. The knowledge of instantan...2014-01-01
55 Smith, Philip J.Reduced-order PCA models for chemical reacting flowsOne of the most challenging aspects of turbulent combustion research is the development of reduced-order combustion models which can accurately reproduce the physics of the real system. The identification and utilization of the low dimensional manifolds in these system is paramount to understand and...2014-01-01
56 Eddings, Eric G.Joint NSF-NSFC Workshop on Combustion Related to Sustainable EnergyA workshop on Combustion Related to Sustainable Energy was held in Hangzhou, China on March 10-12, 2014. The workshop was jointly sponsored by the U.S. National Science Foundation (NSF) and by the National Science Foundation of China (NSFC). The purpose of the workshop was to bring together a limite...Combustion, sustainable energy, research needs, climate change, renewable fuel, efficiency, Workshop China2016
57 Rashid, Khalid; Powell, KodyDynamic simulation, control, and design of a novel solar thermal hybrid power plantSolar power is among the promising technologies leading towards cleaner fuel. However, there are still technological challenges regarding the reliability of power generation due to its intermittency. This work demonstrates the synergies that exist in integrated hybrid systems, where a dispatchable f...Solar energy--Research; Solar thermal energy--Research; Solar power plants--Research2017
58 Eddings, EricModified CPD Model for Coal Devolatilization at UCTT ConditionsTo study coal pyrolysis behavior at underground coal thermal treatment (UCTT) conditions, a modified CPD (M-CPD) model was developed and evaluated using two scales of experiments as well as two different coals, Utah Sufco and Illinois #6. Compared with the original CPD model, three major aspects wer...Coal; pyrolysis; modeling; underground heating2019
59 Eddings, Eric G.Experimental and numerical investigation on sulfur transformation in T pressurized oxy-fuel combustion of pulverized coalPressurized oxy-fuel combustion, as a novel and promising technology for CO2 capture from power plants, has attracted worldwide attentions. The high partial pressure of CO2 induces significant changes to the SOx release characteristic. Properly addressing these fundamental issues and technological c...Pressurized; Oxy-fuel combustion; SO2 emission; Numerical; Pulverized coal2019

61 McLennan, JohnLarge-scale subsurface seasonal heat storage for future valueI too extend my welcome. And, I extend thanks to the NSF for the support of this research at the Univ. of Utah. The concept of storing heat in the ground is certainly not new. Many, many cases have investigated heat to be stored underground. Getting the heat underground is somewhat of a problem, but...2020-05-19
62 McLennan, JohnFinal Report Geothermal Battery Energy StorageSolar and wind power are being introduced into electric grids to supplement and replace conventional electricity production. The deployment of utility-scale storage has not kept pace to overcome the intermittent nature of solar and to a lesser extent wind. Large-scale energy storage is cur...2020-06
