چکیده
Abstract An experimental setup is built to determine the thermal conductivity of a mixture KNO3 and NaNO3 with ratio 54-46m% which used in high temperature storage systems. The measurement principle based on transient parallel hot-wire method described standards NBN B 62-202 ISO 8892-2. designed measure around melting (<300°C). Measurements within liquid region show faulty results caused by natural convection sample. measured solid 0.5466-0.5529W/mK close point 0.7174W/mK at room temperature, shows decreasing increasing region.

Thermal Conductivity of Saturated Liquid Toluene by Use of Anodized Tantalum Hot Wires at High Temperatures
Absolute measurements of the thermal conductivity of a distilled and dried sample of toluene near saturation are reported. The transient hot-wire technique with an anodized tantalum hot wire was used. The thermal conductivities were measured at temperatures from 300 K to 550 K at different applied power levels to assess the uncertainty with which it is possible to measure liquid thermal conduct...

As a result of a revision of the JIS system, the application of the hot wire method for determining thermal conductivity has been expanded from heat-insulating bricks to refractories with higher heat conductivity. In this regard, focusing on magnesia bricks, which are used in the safety lining of converters and a wide variety of other applications, the authors studied the possibility of applyin...
متن کاملA High-Temperature Transient Hot-Wire Thermal Conductivity Apparatus for Fluids
A new apparatus for measuring both the thermal conductivity and thermal diffusivity of fluids at temperatures from 220 to 775 K at pressures to 70 MPa is described. The instrument is based on the step-power-forced transient hot-wire technique. Two hot wires are arranged in different arms of a Wheatstone bridge such that the response of the shorter compensating wire is subtracted from the respon...

متن کاملAlgorithm to optimize transient hot-wire thermal property measurement.
The transient hot-wire method has been widely used to measure the thermal conductivity of fluids. The ideal working equation is based on the solution of the transient heat conduction equation for an infinite linear heat source assuming no natural convection or thermal end effects. In practice, the assumptions inherent in the model are only valid for a portion of the measurement time. In this st...
