Abstract

The present invention relates to an apparatus and method for measuring the convective heat transfer coefficients of nanofluids, which can realize a small-sized structure and can accurately control the movement velocity of a hot wire sensor within a fluid. The apparatus for measuring the convective heat transfer coefficients of nanofluids according to the present invention includes a sensor unit, a transfer unit and a liquid container. The transfer unit is formed on the sensor unit and is configured to allow the sensor unit to longitudinally reciprocate in a direction parallel to a ground surface with the sensor unit spaced apart from the ground surface. The liquid container is arranged below and spaced apart from the sensor unit, and is configured to allow a nanofluid or a base fluid, a convective heat transfer coefficient of which needs to be measured, to be put therein.
