Giant magnetostriction in annealed Co1 − xFex thin-films

Creator:

Hunter, Dwight, Osborn, Will, Wang, Ke, Kazantseva, Nataliya, Hattrick-Simpers, Jason, Suchoski, Richard, Takahashi, Ryota, Young, Marcus L., Mehta, Apurva, Bendersky, Leonid A., Lofland, Sam E., Wuttig, Manfred, and Takeuchi, Ichiro

Abstract:

Chemical and structural heterogeneity and the resulting interaction of coexisting phases can lead to extraordinary behaviours in oxides, as observed in piezoelectric materials at morphotropic phase boundaries and relaxor ferroelectrics. However, such phenomena are rare in metallic alloys. Here we show that, by tuning the presence of structural heterogeneity in...

Modeling multidisciplinary design with multiagent learning

Creator:

Hulse, Daniel, Tumer, Kagan, Hoyle, Christopher, and Tumer, Irem

Abstract:

Complex engineered systems design is a collaborative activity. To design a system, experts from the relevant disciplines must work together to create the best overall system from their individual components. This situation is analogous to a multiagent system in which agents solve individual parts of a larger problem in a...

Performance enhancement of a thermally activated cooling system using microchannel heat exchangers

Creator:

Wang, Hailei and Peterson, Richard B.

Abstract:

In the current study a thermally activated cooling system that combines an ORC system with a vapor compression cooling cycle was developed and tested under laboratory conditions. This combined system can utilize waste heat or other thermal sources such as solar and geothermal to generate power and cooling. Hot oil...

Evaluation of Heat and Mass Transfer Models for Sizing Low-Temperature Kalina Cycle Microchannel Condensers

Creator:

Fronk, Brian M. and Zada, Kyle R.

Abstract:

Waste heat driven ammonia/water Kalina cycles have shown promise for improving the efficiency of electricity production from low-temperature reservoirs (T < 150 °C). However, there has been limited application of these systems to utilize widely available, disperse, waste heat streams for smaller scale power production (1–10 kWe). Factors limiting increased deployment of these...

Evaluation of Governing Heat and Mass Transfer Resistances in Membrane Based Energy Recovery Ventilators with Internal Support Structures

Creator:

Armatis, Paul D. and Fronk, Brian M.

Abstract:

Energy recovery ventilators (ERVs) are an effective way to reduce energy consumption in buildings while satisfying ventilation standards. As membrane technology and manufacturing methods improve, membrane based ERVs are seeing increased market penetration. In the present study, the feasibility of membrane ERV designed to fit in a commercial building wall...

Evaluation of Network Expansion Decisions for Resilient Interdependent Critical Infrastructures with Different Topologies

Creator:

Tiong, Achara and Vergara, Hector A.

Abstract:

Resilient interdependent critical infrastructures (CIs) can better withstand cascading failures in disruptive events. This study proposes network expansion as a resilience improvement strategy for interdependent CIs and evaluates the influence of topology in interdependent network design for resilience optimization under disruption uncertainty. A resilience score consisting of network complexity and...

Simulation of thermal hydraulic performance of multiple parallel micropin arrays for concentrating solar thermal applications with supercritical carbon dioxide

Creator:

Hyder, Matthew B. and Fronk, Brian M.

Abstract:

Concentrated solar power (CSP) plants have the potential to provide 24 h, renewable electricity. Current CSP systems have high capital and operational costs which makes the levelized cost of electricity uncompetitive with conventional techniques. Recent experimental research has shown the potential of small unit cells (up to 2 × 2 cm) containing micropin arrays...

Experimental Investigation of In-Tube Condensation of Low GWP Refrigerant R450A using a Fiber Optic Distributed Temperature Sensor

Creator:

Jacob, Tabeel A., Matty, Ethan P., and Fronk, Brian M.

Abstract:

Heat transfer coeﬃcients and frictional pressure drop values are experimentally measured during condensation of R134a and its proposed low global warming potential (GWP) replacement, R450A. R450A is a non-ﬂammable zeotropic mixture of R134a and R1234ze (42/58% by mass). Experiments were conducted in a horizontal tube (ID = 4.7 mm) for...

Numbering-Up of Microscale Devices for Megawatt-Scale Supercritical Carbon Dioxide Concentrating Solar Power Receivers

Creator:

Zada, Kyle R., Hyder, Matthew B., Drost, M. Kevin, and Fronk, Brian M.

Abstract:

Concentrated solar power (CSP) plants have the potential to reduce the consumption of nonrenewable resources and greenhouse gas emissions in electricity production. In CSP systems, a field of heliostats focuses solar radiation on a central receiver, and energy is then transferred to a thermal power plant at high temperature. However,...

Two-phase flow regimes of condensing R-134a at low mass flux in rectangular microchannels

Creator:

Vanderputten, Michael A., Jacob, Tabeel A., Sattar, Maria, Ali, Nouman, and Fronk, Brian M.

Abstract:

Qualitative two-phase flow regime data are obtained from high-speed visualization of condensing flows of R-134a at mass fluxes from 75 to 150 kg m−2 s−1 and quality from 0.1 to 0.8 in square microchannels (DH = 0.84 mm) cooled from a single side. Superheated R-134a is distributed into multiple parallel microchannels and then partially condensed, using...
