ROTATION DISK TYPE FLUID CONVECTIVE HEAT TRANSFER COEFFICIENT MEASURING DEVICE USING HEATING WIRE

摘要

The present invention relates to a rotation disk type fluid convective heat transfer coefficient measuring device using a heating wire. According to an embodiment of the present invention, the rotation disk type fluid convective heat transfer coefficient measuring device using heating wire with a large area can accurately, rapidly, and conveniently evaluate a heat transfer coefficient of a fluid in a condition of a high Re number (rapid fluid speed) in which the fluid flow has a turbulence property. The rotation disk type fluid convective heat transfer coefficient measuring device includes: a container for accommodating a nano fluid; the rotation disk located on the container and rotating around the center of the container; and a heating wire sensor installed on the rotation disk and moving in a radial direction of the rotation disk. While the heating wire sensor is soaked in the nano fluid, the rotation disk is rotated in a preset speed after a position of the radial direction in the heating wire sensor is determined. The fluid convective heat transfer coefficient measuring device supplies heat to the nano fluid by the heating wire sensor and measures a convective heat transfer coefficient of the nano fluid.;COPYRIGHT KIPO 2016
