Transient-temperatures-measurement errors

Estimation of transient temperature measurement errors which is often required to help understand thermal experiments and improve the accuracy of estimated thermal parameters is discussed. Thermal response models used in conjunction with experimental techniques are very effective. A hybrid of finite differences and the unsteady surface element method is developed and used for modeling temperature measurements made with intrinsic thermocouples and resistance temperature detectors. Experimental data obtained with the loop current step response method are used to estimate model parameters.
