  • Method and apparatus for measuring local heat transfer distribution on a surface
    Patent number: 6585408
    Abstract: An apparatus and method for measuring local heat transfer distribution of an object surface. The apparatus includes a heater element for providing heat flux, a member disposed on a surface of the heater element for receiving impinging cooling air. A liquid crystal element is provided on a side of the heater element remote from the surface, and an insulating material is disposed adjacent to the liquid crystal element and remote from the heater element. The apparatus further includes means for determining heat transfer distribution coefficients from the liquid crystal element.
    Type: Grant
    Filed: July 30, 2001
    Date of Patent: July 1, 2003
    Assignee: General Electric Company
    Inventors: Lamyaa Abdel Alle El-Gabry, Steven J. Brzozowski, Nirm V. Nirmalan

  • Method for determining heat transfer performance of an internally cooled structure
    Patent number: 6422743
    Abstract: A method by which the heat transfer quality of a cooled gas engine component can be quantified for inspection purposes. A system is utilized to determine the heat transfer performance of an internally cooled structure, by analyzing the transient thermal response of the structure based upon a full field surface temperature measurement using an infrared thermal imaging system.
