Design, modeling and performance of miniature reciprocating expander for a heat actuated heat pump

Creator:: Herron, Thomas G.
Abstract:: A miniature reciprocating expander is being developed as part of a larger program to develop a heat actuated heat pump for portable applications. By utilizing the higher energy density of liquid hydrocarbon fuels relative to batteries, a heat actuated heat pump would be able to provide cooling for much longer...

Design and optimization of a heating-only heat pump for Western Pacific Northwest applications

Creator:: Elger, Donald Francis
Abstract:: The use of the conventional air-source heat pump for residential space conditioning has increased dramatically over the past decade. Historically these units have been designed as air conditioners which could also be used to provide heating. However, for the climatic region of the Western Pacific Northwest (the geographic region west...

Development of a process for fabricating high-aspect-ratio, meso-scale geometries in stainless steel

Creator:: Walker, Benjamin A.
Abstract:: Miniature energy and chemical systems (MECS) are miniature thermal, fluid, and chemical devices in the mesoscale size range between a sugar cube and a human fist. MECS take advantage of improved rates of mass and heat transfer that have been observed at the microscale. There are many potential applications for...

Constrained thin film desorption through membrane separation

Creator:: Thorud, Johnathan D.
Abstract:: A constrained thin film desorption scheme has been experimentally tested to determine the desorption rates for water from an aqueous lithium bromide mixture through a confining membrane. Variable conditions include the inlet concentration, pressure differential across the membrane, and channel height. Desorption takes place in a channel created between two...

Design considerations for a miniature atmospheric engine with a magnet-actuated autonomously-reciprocating in-cylinder regenerator for portable power production

Creator:: Yarger, David J.
Abstract:: Driven by the need for high energy-density power sources, demand has stimulated the development of small-scale engines. A small-scale engine with a fuel supply could replace batteries and utilize higher energy-density liquid hydrocarbon fuels; such an advance could deliver a new age of portable devices. Currently, operable small-scale engines exist;...

Use of the exergy concept for design improvement of heat exchangers and heat exchanger networks

Creator:: Ranasinghe, Jatila
Abstract:: The second law of thermodynamics, through the exergy concept, allows us to quantify and rationally cost the consumption of exergy (irreversibility) used to drive the heat exchange process and the effluent losses of exergy in a heat exchanger For systems with a network of heat exchangers, the exergy concept recognizes...

Design of a heat exchanger network to challenge controller design methods

Creator:: Pashak, Jeffrey J.
Abstract:: A simple heat exchanger network has been studied as an example of a dynamically interactive process. The process is relatively simple, requiring only temperature measurements and flow rate manipulations. Equations are presented for the design of a physical process having a specified steady-state Relative Gain Array and specified dynamic characteristics....

Adhesive microlamination protocol for low-temperature microchannel arrays

Creator:: Paulraj, Prawin
Abstract:: A new adhesive bonding method is introduced for microlamination architectures, for producing low-temperature microchannel arrays in a wide variety of metals. Sheet metal embossing and chemical etching processes have been used to produce sealing bosses and flow features, resulting in approximately 50% fewer laminae over traditional methods. These lamina designs...

The geometric characterization and thermal performance of a microchannel heat exchanger for diesel engine waste heat recovery

Creator:: Yih, James S.
Abstract:: Rising energy demands and the continual push to find more energy efficient technologies have been the impetus for the investigation of waste heat recovery techniques. Diesel engine exhaust heat utilization has the potential to significantly reduce the consumption of fossil fuels and reduce the release of greenhouse gases, because diesel...
