... local temperature measurements performed by infrared thermography. The heat flux distribution along the wetted side of the slab, computed from an energy balance within the metal domain, ultimately yields the Nusselt number distributions over the ribbed surface. Fig. 1 Conjugate ( a ) versus...

... studies obtained for a single rotating disk or a closed (but unshrouded) rotor–stator system, an air suction comes through the stator and enters the air-gap in this particular work. Determination of Nusselt numbers is based on the use of infrared thermography. The influence of the suction is discussed...

... of the rotor comes through and enters the airgap. A thermal balance equation was used to identify the local convective heat transfer coefficient, with temperatures as boundary conditions, which have been measured by infrared thermography. The influence of the suctions is discussed for an interdisk...

... in the substrate are considered. Experiments are conducted in a high-aspect-ratio rectangular channel using infrared thermography to validate the numerical model and visualize the temperature field on a heated surface. An extended parametric study using the validated model is also carried out to assess the impact...
