  • Fluid monitoring
    Patent number: 12000821
    Abstract: Methods of evaluating mixing are disclosed relating to the preparation and mixing of materials. Materials prepared may transition from heterogeneous mixtures to homogenous mixtures while the current of a motor is monitored. Quantities relating to the rate of change of power or the rate of change of entropy may be calculated in evaluating the sufficiency of mixing. Methods of evaluating lubricant degradation are also disclosed.
    Type: Grant
    Filed: June 10, 2021
    Date of Patent: June 4, 2024
    Assignee: Bd. of Supervisors of La. St. Univ. & A&MCollege
    Inventors: Michael M. Khonsari, Lijesh Koottaparambil
  • Peanut butter evaluation
    Patent number: 11994505
    Abstract: Methods of evaluating viscous compositions are disclosed. These methods may be used to evaluate volumetric properties of fluids including peanut butter. The methods may include preparing a surface for testing by leveling and flattening a viscous composition, placing a drop of a liquid on the flattened leveled surface, evaluating the observed contact angle between the drop and the surface, and then comparing the observed contact angle to a reference contact angle.

  • Grease evaluation
    Patent number: 11686719
    Abstract: Methods of evaluating viscous compositions are disclosed. The methods may be used to evaluate degradation levels of lubricants including grease. The methods may include preparing a surface for testing by leveling and flattening a viscous composition, placing a drop of a liquid on the flattened leveled surface, evaluating the observed contact angle between the drop and the surface, and then comparing the observed contact angle to a reference contact angle.

  • Damage assessment
    Patent number: 11488420
    Abstract: Methods of estimating tribological damage described herein include examples where varying power is applied between surfaces engaged in frictional contact. Calculations evaluate power consumed at the relevant frictional contact and temperature values may be gathered to supplement the calculated power. Instantaneous and cumulative assessments of damage are calculated based on that information. Measurements or calculations of electrical power may be used as part of the damage assessment.
