Abstract
Development of Key Components in High Temperature Energy Systems (HiTES)AbstractSeveral critical issues for advanced technology d"evelopment of high temperature energy systemsare addressed. They include: (i) distributed combustion for green combustion turbines,"" (ii) reforming of wastes and biomass to clean fuels, (iii) miniature high frequency sensor~s development, (iv) high energy density"" fuels and combustion, (v) advanced membranes development for gas separation in syngas, (vi) anisotropic boron nitride development f"or improved performance of engines and (vii) additively manufactured electronic packaging forcustomized housing and interconnections. A brief summary of each task is given below. 1. High intensity volume distributed combustion will provide fundamental understan"ding for achieving near zero emissions, low noise, high flame stability and alleviation of flame dynamics using gas and liquid fuels". Distributed combustion index (DI) will be developed for wider use in high intensity gas turbines. We will examine high pressure combustion conditions using novel atomization scheme with liquid fuels and also demonstrate distributed combustion in a practicalgas turbine engine.2. Pyrogasification will be examined to reform naval wastes and biomass to clean syngas of higher heating value. Role of reactor operational parameters on chemical kinetics pathways in the presence of active metal particles or molten metal will be" evaluated. We will examine product yield quality, liquid products formed, oxygen content and carbon yields for high conversion effi"ciency. Catalytic deoxygenation of major bio-liquid oxygenate mixtures will be examined using methane and methane-hydrogen mixtures. Hybrid ceramic-polymer membranes will be developed for separation and reforming of wastes to pure gases.3. High-temperature combustion of nano-sized magnesium diboride (MgB2) and aluminumdiboride (AlB2) particles is very attractive for propulsion and power applications due to their high volumetric energy density. This task will examine the feasibility of using micro- and nanosized intermeta"llic compounds for air-breathing combustion applications. Due to their metallic bonding, these compounds are inherently more stable" to oxide coating issues than the pure metals previously considered. Low cost of MgB2 powders offers practical solution for their us"e as alternative fuels.4. This task will develop multifunctional high fidelity, robust photonic sensor systems for real-time monito"ring of high temperature energy systems. The key innovations include multifunctional sensing concept realized with high temperature" resistant photonic structures and a multifunctional on-chip sensor interrogator that enables high density, heterogeneous wireless s"ensor networks. This work will lead to new sensing paradigm that can help enhance the performance of next generation high temperature energy systems. 5A. This task will focus on computational design of novel membrane materials to guide development of membranes for experimental use to separate out various gas components in the syngas generated from wastes. The task will use our state-of-the-ar"ts atomistic modelingtechniques to develop, design, and discovery a range of high-performance membrane materials with desired selec""tivity for H2, CO2, and N2, leading to effective gas separation of syngas generated from wastes and biomass. 5B. Computational effo"rts will support experimental efforts at the University of Nebraska-Lincoln (UNL) to further develop this new class of doped Boron carbide materials. We will perform a systematic ab initio atomistic modeling to understand the structure-composition property relatio"nship of this new material as a function of H composition, linker unit and content,dopant, growth conditions, and to enhance the fu"ndamental understanding for this material and its related devices to accelerate the design and development of this material for advanced applications.6.
