A. Badarlis, V. Kumar, A. Pfau & A. Kalfas
Thermal conductivity and thermal diffusivity of fluids are a few of thermo-physical properties which characterize a fluid. Different methods have been developed in previous years for the measurement of these two properties, some of them are transient hot wire, 3ω and temperature oscillation technique. The current investigation is focused on temperature oscillation technique and had the scope of understanding the principle, its limitation and its applicability to an existing gas thermal flow sensor. The investigation...
