Title (EN) RHEOMETER
(FR) RHEOMETRE
Abstract:
(EN) There is provided a rheometer, comprising a cup for a fluid to be measured, a concentric rotor and stator arrangement, and a circuit for circulating the fluid which includes a pump for providing in pulsatile, non-laminar flow in the cup. By using the pump to provide both a turbulent and pulsating flow, particulate matter can be maintained in suspension and flow induced through the measuring system while any rheology effect the pumping system has on the fluid is introduced independently of rheology effects caused by the measuring system itself. Thus, the pumping can be continued while the measurement is being made.
(FR) On décrit un rhéomètre, comprenant un récipient destiné à un fluide devant être mesuré, un agencement de rotor et stator concentrique, et un circuit servant à faire circuler le fluide, qui comprend une pompe produisant un écoulement pulsant et non laminaire dans le récipient. Lorsqu'on utilise la pompe pour créer un écoulement à la fois turbulent et pulsant, la matière particulaire peut être maintenue en suspension et l'écoulement amené à travers le système de mesurage, alors que tout effet rhéologique produit par le système de pompage sur le fluide est introduit indépendamment des effets rhéologiques produits par le système de mesurage lui-même. Le pompage peut ainsi se poursuivre pendant que le mesurage est effectué.
