  • Apparatus for measuring rheological parameters and methods for its operation
    Patent number: 9958367
    Abstract: An apparatus for measuring rheological parameters of a multi-phase fluid is provided. The apparatus includes a static chamber containing a multi-phase fluid having at least a first phase and a second phase. The apparatus also includes a rotor member submersed in the multiphase fluid in the static chamber. The rotor member includes a first set of threads formed on a first portion of the rotor member submersed in the first phase of the multi-phase fluid and a second set of threads formed on a second portion of the rotor member submersed in the second phase of the multi-phase fluid.
    Type: Grant
    Filed: April 9, 2014
    Date of Patent: May 1, 2018
    Assignee: INDIAN INSTITUTE OF TECHNOLOGY MADRAS
    Inventors: Jitendra Sangwai, Chirag Khalde
  • Methods and apparatus for measuring rheological properties of multi-phase fluids
    Patent number: 9863860
    Abstract: An apparatus for measuring rheological properties of a multi-phase fluid is provided. The apparatus includes a static chamber configured to contain a multi-phase fluid having at least a first phase and a second phase. The apparatus also includes a rotor member submersed in the multi-phase fluid in the static chamber. The rotor member is rotatable about a horizontal rotational axis within the static chamber and the static chamber and the rotor member are oriented in a substantially horizontal direction.
