- Abstract
- In this study, we classify the difference of heat transfer coefficient regarding to the temperatuer using thermal mass flowmeter. In using gas, the experiment condition regarding to temperature was generally ignored due to its characteristic of properties. In this experiment we focused on using water which properties(destiny, specific heat) relatively high than gas to figure out the characteristic changes in termsof various conditions of temperature. The experiment was carried out at a certain range(20℃,50℃ 80℃). By changing the velocity of water at each temperature, the heat transfer coefficient was measured at 8자형 sensor which have separated RTD and heater. Throughout this study we can analyze the characteristic curve between fluid and temperature and abtain specific experimental equation.
