Abstract

This study numerically investigates the effect of rotation on the uniformity of temperature distribution in pipeline insulation, as well as the accuracy of measuring thermal conductivity for a pipe using the steady- state flux approach with non-uniform external heat transfer. It is shown that the use of rotation uniforms temperature fields and radial heat flux inside the insulation, allowing thermal conductivity tests to be accurate to 0.1%. The effect has been validated for a variety of insulating properties, including porous materials with high permeability.
