"Index of Dushman 1998" most likely refers to the Villermaux-Dushman reaction
, a chemical test protocol used to measure the efficiency of micromixing
in chemical reactors. Although the reaction itself was developed by Saul Dushman in the early 20th century, researchers in the late 1990s (notably Villermaux et al.) popularized it as a standard "mixing index" for chemical engineering.
Below is a draft paper summarizing the "index" or method as it relates to chemical engineering research from that era.
Characterization of Micromixing Efficiency via the Villermaux-Dushman Protocol (1998)
This paper explores the application of the iodide-iodate reaction, commonly known as the Dushman reaction
, for characterizing micromixing intensity in stirred tank reactors and micromixers. By utilizing a system of parallel competitive reactions, researchers can derive a segregation index ( cap X sub s
) that quantifies the degree of non-ideal mixing at the molecular scale. This method became a cornerstone of chemical engineering performance metrics in the late 1990s. 1. Introduction
In chemical reactor design, "micromixing" refers to mixing at the molecular level, which is critical for fast, complex reactions where the rate of mixing may be slower than the rate of reaction. The Villermaux-Dushman method
provides a quantitative "index" to evaluate this performance. 2. The Chemical System
The protocol relies on two competing reactions occurring simultaneously: Neutralization (Fastest): An acid-base reaction that is essentially instantaneous. Redox (Dushman Reaction): The reaction between iodide ( cap I raised to the negative power ) and iodate ( cap I cap O sub 3 raised to the negative power ) in the presence of acid to produce iodine ( cap I sub 2
In a perfectly mixed system, the acid is consumed entirely by the neutralization reaction. However, in poorly mixed regions, local acid surpluses trigger the Dushman reaction, producing iodine which can be measured spectrophotometrically. 3. Calculating the Segregation Index ( cap X sub s The "index" of mixing is typically expressed as the Segregation Index cap X sub s : Represents perfect micromixing (no iodine produced). : Represents total segregation (maximum iodine production). 4. Significance in 1998 Research
By 1998, this method was standardized to allow researchers to compare different mixer geometries—such as T-mixers and stirred vessels—using a universal benchmark. It remains a primary tool for validating Computational Fluid Dynamics (CFD) models in turbulent and laminar flows. 5. Conclusion index of dushman 1998
The Dushman 1998 "index" (as established in the Villermaux-Dushman protocol) remains an essential experimental tool for diagnosing mixing deficiencies and optimizing the yield of mass-transfer-limited chemical processes. Alternative Context
