Fitch method thermal conductivity
WebFlash Method. The flash method is widely used for measuring the thermal conductivity of a thin sample material that is about the size of a coin. The sample material is submitted … WebDec 21, 2024 · Abstract: In this paper an electro-thermal method is used for measuring the thermal conductivity of liquids. This technique is based on eight heat sensing resistors which are connected to form a Wheatstone bridge. Measurements performed on several liquids covering a wide range of thermal properties validate the method.
