SBIR Phase II: A Novel Instrument for the Determination of Extensional Rheology

这个小型企业创新研究第二阶段项目描述了毛细管破裂流变仪（CaBER）的开发，从经过验证的试验板设计到商业上可行的分析和过程控制功能仪器。本文件概述了成功完成第一阶段SBIR的结果。 CaBER组件的基本操作由验证所选组件和验证设计适用性的数据支持。此外，模型流体的样本数据将用于说明CaBER的功能，并突出该仪器的广泛适用性。CaBER的持续发展包括更强大的软件分析，更便宜的制造成本和更直观的用户界面。这些改进将产生一种在研究实验室和过程控制环境中对工业都非常宝贵的仪器。 目前只有一种商用拉伸流变仪和少数学术流变仪设计。 通过提供一个几乎独特的工具，用于确定拉伸粘度在一个自由排放的流体线程，该仪器将填补一个部分的仪器领域，因为在这里以前被忽视。

This Small Business Innovation Research Phase II project describes the development of a Capillary Breakup Rheometer (CaBER) from a proven breadboard design to a commercially viable instrument for both analytical and process control functions. In this document the results of the successful completion of a Phase I SBIR are outlined. The fundamental operation of the CaBER's component parts is supported by data that validates the chosen components and verifies the suitability of the design. In addition, sample data from model fluids will be used to both illustrate the functionality of the CaBER and to highlight the broad applicability of the instrument. Ongoing developments of the CaBER include more robust software analysis, cheaper manufacturing costs and a more intuitive user interface. These improvements will result in an instrument that is invaluable to industry in both a research laboratory and a process control environment. Currently there is only one commercially available extensional rheometer and a handful of academic rheometer designs. By providing a virtually unique tool for the determination of extensional viscosity in a freely draining fluid thread, this instrument will fill a segment of the instrumentation field that as here to fore been neglected.
