A novel conical injector type swirl generator (CITSG) is devised in this study. Performances of heat transfer and pressure drop in a pipe with the CITSG are experimentally examined for the CITSGsʹ angle (α) of 30°, 45° and 60° in Reynolds number (Re) rang

Infrared thermography is more convenient and faster than other temperature measurement devices such as thermocouples to measure more points or surfaces at the same time. In order to capture infrared thermograph of these surfaces, an infrared thermal camera which has a spectral range between 7.5 and 13 µm was used. Using this technique will lead us to determine the instant and transient temperature distributions of all surfaces inside an automobile and investigate the thermal discomfort that was caused by those surfaces.
