Paper Abstract

The temperature field of a horizontal cylinder in natural convection is studied experimentally using a lateral shearing interferometer (LSI) with a large shear amount. Real-time interferograms are obtained with and without the cylinder. The surface temperature of the cylinder dropped from 693.15 K to the ambient temperature 289.03 K. The temperature distribution around the cylinder was reconstructed and fitted using exponential and six-degree-polynomial functions. For high surface temperature, the results indicate that the six-degree-polynomial function has a considerable advantage over the exponential one. Experimental data were compared with that measured by thermocouples within a 0.19% derivation. LSI with a large shear amount can provide accurate measurement of the temperature field around a cylinder with a high surface temperature.
