Measurement of in-plane thermal diffusivity of solids moving at constant velocity using laser spot infrared thermography
Bedoya Pérez, Adrián Felipe; González, Jorge; Rodríguez Aseguinolaza, Javier ; Mendioroz Astigarraga, María Aránzazu ; Sommier, Alain; Batsale, Jean-Christophe; Pradere, Christophe; Salazar Hernández, Agustín (Elsevier, 2018-11-07)In this work, an infrared thermography setup is proposed to measure the in-plane thermal diffusivity of (an)isotropic samples that are moving at constant velocity, as it is the case of in-line production or in-line quality ... -
Measurement of the thermal conductivity of fluids using laser spot lock-in thermography
Bedoya Pérez, Adrián Felipe; Colom Serra, Mateu ; Mendioroz Astigarraga, María Aránzazu ; Salazar Hernández, Agustín ; Marín Moares, Ernesto (Elsevier, 2020-03-25)In this work, we propose a new method to retrieve the thermal conductivity of fluids, kf, using laser spot lock-in infrared thermography. The measurement cell consists in two paralepidid blocks separated by a narrow gap ... -
Measuring the in-plane thermal diffusivity of moving samples using laser spot lock-in thermography
Colom Serra, Mateu ; Bedoya Pérez, Adrián Felipe; Mendioroz Astigarraga, María Aránzazu ; Salazar Hernández, Agustín (Elsevier, 2020-01-21)In this work we deal with samples that move at constant speed and are illuminated by a modulated and focused laser beam. We have obtained a general expression for the surface temperature of these moving samples: it is valid ... -
Measuring the thermal resistance of vertical interfaces separating two different media using infrared thermography
González, Jorge; Bedoya Pérez, Adrián Felipe; Mendioroz Astigarraga, María Aránzazu ; Salazar Hernández, Agustín (Elsevier, 2019)We propose a method to measure the thermal contact resistance at the vertical interface between two materials using lock-in infrared thermography with laser spot heating. We found an analytical expression for the surface ...
