Infrared Imaging in Engineering Applications

From Flir Systems Incorporated
 

 

Temperature variations that provide valuable information about heat transfer and fluid phenomena that occur during a mechanical and chemical process stand out clearly in an infrared image. An overview is given for three different mechanical engineering projects currently using infrared imaging to describe high-speed thermal events and provide experimental data for computational models. The first project involves conducting experimental measurements and numerical simulations to investigate the effect of mist on the spray heat transfer and fluid dynamics in the cooling of a cylindrical surface heated to the nucleate boiling temperature range. Infrared imaging (FLIR A40) is used to capture the effect of the spray flow conditions on the droplets transportation process around the heated cylinder.
