The Impact of a New Instrument on the Development of Scientific Domain

Cozzens博士正在与法国CNRS的物理学家Iskender Gokalp博士合作，研究将激光多普勒测速技术(LDA)引入湍流和湍流燃烧研究领域的背景和影响。此案之所以意义重大，原因有很多。该领域是一个具有重大技术和社会后果的重要领域。它是一个跨学科领域的例子，不同的贡献领域之间有很强的互动。LDA带来的变化是剧烈的，因此创造了一个比较该领域革命性和演进性变化的机会。纯湍流和湍流燃烧研究界对LDA的看法不同，一个立即纳入，另一个在一段时间内抵制。这种对比为研究促进和抑制仪器扩散的因素提供了一种自然的比较设计。LDA是在一个竞争激烈、技术潜力很强的领域引入的。此案还允许调查人员比较不同国家系统对具有实际后果的变化的反应。最后，这是一个最近的案例，使得研究相对方便。Gokalp博士和Cozzens博士正在通过分析文件、采访和现场访问，在合作的基础上探索这一案件。这项研究的一部分建立了实验室引入LDA的过程的数据库。另一种分析了LDA对湍流燃烧领域本身的影响。第三个涉及个别实验室的案例研究，以更深入地探讨该仪器的纳入过程。

Dr. Cozzens, working with Dr. Iskender Gokalp, a physical scientist at the CNRS in France, are investigating the context and impact of the introduction of laser doppler anemometry (LDA) into the domains of turbulence and turbulent combustion studies. The case is significant for a number of reasons. The domain is an important one with strong technological and social consequences. It is an example of an interdisciplinary field with strong interactions between different contributing areas. The changes introduced by LDA are drastic, and thus create an opportunity to compare revolutionary and evolutionary changes in the field. the pure turbulence and turbulent combustion research communities received LDA differently, with one incorporating it immediately and the other resisting for some time. The contrast provides a natural comparative design for studying the factors that facilitate and inhibit diffusion of instruments. LDA was introduced in a highly competitive domain with strong technological potentialities. The case also allows the investigators to compare the response of different national systems to changes with practical consequences. Finally, it is a recent case which makes it relatively convenient to study. Drs. Gokalp and Cozzens are exploring the case on a collaborative basis through analysis of documents, interviews and site visits. A portion of the research builds a data base on the process through which laboratories introduced LDA. Another analyzes LDA's impact on the field of turbulent combustion itself. A third involves case studies of individual laboratories, to explore in more depth the process of incorporation of the instrument.
