METHOD AND INSTALLATION FOR DETERMINING RHEOLOGICAL CHARACTERISTICS OF A FLUID, AND CORRESPONDING IDENTIFYING METHOD

摘要

The method comprises: causing a reference fluid (F2) having known rheological characteristics, and an unknown fluid (F1) to flow in parallel in a microchannel (126); identifying at least one data item representative of the interface (I) between these fluids in the parallel flow, and in particular the position of said interface; and determining the rheological characteristics of the unknown fluid, from the or each identified data item.
