Modeling, transient simulations and parametric studies of parabolic trough collectors with thermal energy storage

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 algorithm is developed for managing various working conditions. The model is transient inside the components and responds with hourly weather and demand data. The main purpose of this work is providing an alternative design methodology that focuses on the collector field, and storage size by investment, location, and load type.


Application of Nanoparticle Antioxidants to Enable Hyperstable Chloroplasts for Solar Energy Harvesting
Boghossian, Ardemis A.; Sen, Fatih; Gibbons, Brenna M.; Sen, Selda; Faltermeier, Sean M.; Giraldo, Juan Pablo; Zhang, Cathy T.; Zhang, Jingqing; Heller, Daniel A.; Strano, Michael S. (Wiley, 2013-07-01)
The chloroplast contains densely stacked arrays of light-harvesting proteins that harness solar energy with theoretical maximum glucose conversion efficiencies approaching 12%. Few studies have explored isolated chloroplasts as a renewable, abundant, and low cost source for solar energy harvesting. One impediment is that photoactive proteins within the chloroplast become photodamaged due to reactive oxygen species (ROS) generation. In vivo, chloroplasts reduce photodegradation by applying a self-repair cycl...
Feasibility analysis and proof of concept for thermoelectric energy harvesting in mobile computers
Denker, R.; Muhtaroglu, A. (AIP Publishing, 2013-03-01)
Thermoelectric (TE) energy harvesting in compact microelectronic systems necessitates detailed upfront analysis to ensure unacceptable performance degradation is avoided. TE integration into a notebook computer is empirically investigated in this work for energy harvesting. A detailed finite element model was constructed first for thermal simulations. The model outputs were then correlated with the thermal validation results of the selected system. In parallel, a commercial TE micro-module was empirically c...
Thermoelectric polymer films with a significantly high Seebeck coefficient and thermoelectric power factor obtained through surface energy filtering
Guan, Xin; Yıldırım, Erol; Fan, Zeng; Lu, Wanheng; Li, Bichen; Zeng, Kaiyang; Yang, Shuo-Wang; Ouyang, Jianyong (Royal Society of Chemistry (RSC), 2020-07-01)
Thermoelectric (TE) polymers have unique advantages in converting heat into electricity. But their Seebeck coefficient is lower than that of inorganic TE materials by about one order of magnitude. Here, surface energy filtering is proposed to significantly enhance the Seebeck coefficient of TE polymers. The as-prepared poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS, the most popular TE polymer) films from aqueous solution have a low Seebeck coefficient of 15-18 mu V K(-1)and a power fact...
Concentrated Solar Power Harvesting Using Self-powered, Wireless, Thin-profile, Lightweight Solar Tiles
Ardanuc, Serhan M.; Lal, Amit; Jones, Samuel C. (ASME International, 2011-08-01)
This paper presents a modular and scalable approach to concentrated solar power (CSP) harvesting by using low-profile, light-weight, sun-tracking, millimeter-to-centimeter-scale mirror arrays that can be wirelessly controlled to reflect the incident solar energy to a central receiver. Conventional, utility-scale CSP plants use large-area heliostats, parabolic troughs, or dish collectors that are not only heavy and bulky, but also require significant labor for installation and maintenance infrastructure. Fur...
PEM fuel cell degradation effects on the performance of a stand-alone solar energy system
ÖZDEN, Ender; Tarı, İlker (Elsevier BV, 2017-05-04)
After comparing fresh and degraded performances of Polymer Electrolyte Membrane (PEM) based components of a hydrogen cycle with the help of computational fluid dynamics simulations, recently established stand-alone solar energy system producing hydrogen for energy storage is investigated focusing on the effects of degradation of fuel cells on the overall performance of the system. A complete model of the system has been developed using TRNSYS, and a degraded PEM Fuel Cell Subsystem has been incorporated int...
