APPARATUS AND METHOD FOR MEASURING DYNAMIC THERMAL CONDUCTIVITY OF MICRO-STRUCTURED FLUID

PURPOSE: An apparatus and a method for measuring the dynamic thermal conductivity of microstructured fluid are provided to measure accurate dynamic thermal conductivity by minimizing heat loss. CONSTITUTION: An apparatus(100) for measuring the dynamic thermal conductivity of microstructured fluid comprises an upper fixing plate(110a), a lower fixing plate(110b), a lower body(150b), a rotation plate(120), a shaft(140), a heater, and a thermocouple. The upper and lower fixing plates are vertically separated from each other. The lower body forms the side surface of the space formed between the upper and lower fixing plates. The rotation plate is installed between the upper and lower fixing plates. The shaft is coupled to the rotation plate through the upper fixing plate. The heater is installed on the top of the fixing plate. The thermocouple is installed in the upper and lower fixing plates.
