  • Methods and apparatus for measuring temperature and heat flux in a material using ultrasound
    Patent number: 8256953
    Abstract: Methods and apparatus for measuring heat flux in a material are disclosed. A disclosed example method involves emitting an acoustic signal into the material and determining a first propagation time associated with the propagation of the acoustic signal through the material. A first heat flux value indicative of a first heat flux of the material is then determined based on the first propagation time.
    Type: Grant
