Measurement apparatus for thermal conductivity in steady-state of liquids and gases.
This is a measurement experimental device for the thermal conductivity of liquids and gases in a steady state. A calibration using air is conducted to improve measurement accuracy.
Educational experimental device for steady and unsteady heat conduction experiments.
This device is used to determine the thermal conductivity of samples from the solutions of the fundamental equation of unsteady heat conduction and experimental values, helping to understand unsteady heat conduction phenomena. 【Features】 ○ Copper and aluminum cylinders are used as samples. ○ One end of the sample is heated and cooled to create an unsteady state. ○ The temperature of the sample is measured over time, and the amplitude and phase are obtained. These values are then substituted into the solution of the differential equation to determine the thermal conductivity. (Tokyo University, Wada method) ○ Experimental items - Square wave heating experiment (unsteady) - Amplitude ratio reference thermal conductivity calculation - Phase difference reference thermal conductivity calculation - Thermal conductivity calculation considering heat dissipation - Experiments and thermal conductivity calculation using the steady-state method ○ Device dimensions: 1200mm(W) × 480mm(D) × 1200mm(H)
