Abstract
A method for evaluating a multiphase fluid includes adding the multiphase fluid to an annular volume of a test apparatus, the test apparatus including an inner cylinder deployed in an outer cylinder thereby defining the annular volume. The inner and outer cylinders are configured to rotate independently with respect to one another. The method further includes rotating at least one of the inner and outer cylinders after adding the multiphase fluid to the annular volume to simulate desired flow conditions in the annular volume. The method still further includes removing the multiphase fluid from the annular volume after rotating and evaluating at least one physical property of the removed multiphase fluid.
Claims20
An apparatus for evaluating a multiphase fluid, the apparatus comprising:
- an inner cylinder deployed in an outer cylinder, the deployment defining an annular volume between an outer surface of the inner cylinder and an inner surface of the outer cylinder;
- first and second end covers deployed on opposing axial ends of the inner and outer cylinders, the first and second covers configured to seal the annular volume;
- a first motor configured to rotate the inner cylinder with respect to the first and second end covers;
- and
- a second motor configured to rotate the outer cylinder with respect to the first and second end covers,
- wherein the inner and outer cylinders are configured to rotate independently with respect to one another.
