A Manufacturing Process Design for Producing a Membrane-based Energy Recovery Ventilator with High Aspect Ratio Support Ribs

Creator:: Kawula, Steven P.
Abstract:: Heating, ventilation, and air conditioning systems represent nearly half of building energy usage in the United States. Recent building regulations requiring increased air turnover within buildings will result in even greater air conditioning usage. To alleviate these concerns, membrane-based heat-and-moisture exchangers known as energy recovery ventilators have been developed to...

A microchannel-based thermal management system for hydrogen storage adsorbent beds

Creator:: Steigleder, Leif J.
Abstract:: Hydrogen has been shown to be a promising replacement for fossil fuels for use in light duty vehicles because it is a clean, renewable and plentiful resource with a high gravimetric energy density. However, in order to obtain an acceptable volumetric energy density, densification of the hydrogen is required. Adsorptive...

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...

Application of buckling behavior to evaluate and control shape variation in high-temperature microlamination

Creator:: Wattanutchariya, Wassanai
Abstract:: The miniaturization of energy, chemical and biological systems for distributed and portable applications, known as process intensification, is realized by the enhancement in heat and mass transfer performance within high surface-to-volume ratio microchannels. Fabrication of devices for process intensification is achieved in part by microlamination techniques. These techniques consist of...

Application of controlled thermal expansion in diffusion bonding for the high-volume microlamination of MECS devices

Creator:: Pluess, Christoph
Abstract:: Diffusion bonding has been widely used within microlamination architectures for the fabrication of Micro Energy and Chemical Systems (MECS). MECS are microsystems with the ability to process bulk amounts of fluid within highly-parallel microchannel arrays capable of accelerated heat and mass transfer. Thus far, diffusion bonding of the microchannel arrays...

Application of ultrasonic welding to the rapid prototyping of microfluidic systems for biotechnology

Creator:: Aramphongphun, Chuckaphun
Abstract:: This paper introduces an alternative technique for the development of microfluidic systems for biotechnology based on mechanical machining and ultrasonic welding. Advantages of this approach over existing prototyping approaches involving the rapid development of tooling include: (a) short cycle time, (b) design flexibility, and (c) low cost manufacturing. In addition,...

Characterization and Prediction of Reactive Forces for Compressed 3D Printed Hyperelastic Lattice Structures

Creator:: So, David M.
Abstract:: In order to generate practical ways to easily design functional flexible lattice structures, this research seeks to find a way to predict reactive forces of compressed hyperelastic cubic lattice structures. Using 3D printed test coupons, material data was collected for use in finite element analysis. Cubic lattice structures with varying...

Characterization of a diffusion soldering process for micro-technology-based energy and chemical systems manufacturing

Creator:: Gabriel, Michael A.
Abstract:: Several 316 stainless steel meso-scopic devices were made using a diffusion soldering process. Tensile strength and pressure drop of the devices were measured and metallurgical examinations were made of the joints. Continuous bonds were observed in the sample cross-section specimens. Strengths of the diffusion soldered joints were up to 56%...

Comparison of two microvalve designs fabricated in mild steel using microprojection welding and capacitive dissociation

Creator:: Terhaar, Tyson J.
Abstract:: Since the dawn of the computer age, there has been a push to create miniature devices. These devices were initially integrated circuit (IC) devices to perform calculations for computers. As the technology progressed, the scope of the devices diverged to included microelectromechanical (MEMS) devices, meaning that the devices perform mechanical...

Computer aided tolerance analysis and process selection for AutoCAD

Creator:: Pamulapati, Sairam V.
Abstract:: The fundamental objective of a design engineer in performing tolerance technology is to transform functional requirements into tolerances on individual parts based on existing data and algorithms for design tolerance analysis and synthesis. The transformation of functional requirements into tolerances must also consider the existing process capabilities and manufacturing costs...
