Abstract: The paper presents an analytical and numerical model of a thermal flow metre. The temperature distribution along the thermal flow metre is presented. Results show a very good conformity between numerical and analytical model. Besides the calculation, experimental results are presented, where the duct wall temperature was measured. The author performed a test to measure temperature of duct wall surface. The dependency of mass flow rate in terms of the duct surface temperature difference ṁ = f(ΔT) was developed. Obtained results represent a strong background for further research and investigation of the thermal flow metre and its application for measuring the flow rate of liquids.
Keywords: thermal flow metre; heat transfer; conjugated heat transfer; CFD; measurements.
