Book excerpt: The accuracy of the thermal transmittance, or U-factor, of a fenestration system measured in a building assembly thermal test facility depends upon the test apparatus, test conditions, operating procedure, and the specimen properties. By conducting the uncertainty analysis of a specific thermal test facility, the measurement uncertainty can be identified and quantified. The estimation procedure for the uncertainty associated with the U-factor result for a test apparatus should be established and reported with the measurement of the U-factors of fenestration products. In a study on the University of Massachusetts Research Calibrated Hot Box, detailed analyses of the elemental uncertainties associated with the basic measurements and uncertainty propagation on U-factor results have been performed. In the analysis of uncertainty ropagation, the Root Sum Square (RSS) method was used extensively. The procedure for uncertainty analysis used for this test apparatus can be used in any ASTM C 1363 hot box thermal test facility including those also using ASTM C 1199 for fenestration U- factor measurements. Using the uncertainty analysis procedure described in detail in this paper, a plastic-faced Calibration Standard Transfer (CTS) is analyzed. The results show a reasonable uncertainty level for the U-factor measurement made using ASTM C 1199.The improvement of the U-factor uncertainty can be achieved by reducing the uncertainties associated with the test specimen flanking heat transfer and the metering chamber extraneous heat transfer in the hot box test apparatus.

Download or read book Design Fabrication Calibration and Testing of High temperature Sensors for Measurement of Surface Heat Flux Temperature and Total Heat Transfer written by Justin Alfred Myrick (Jr.) and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation outlines the design, fabrication, calibration and testing of sensors that can be used to measure surface heat flux, surface temperature and total surface heat transfer. These sensors, once calibrated, use in-depth thermocouple (TC) data to estimate the surface boundary conditions which allows operation at high temperatures and harsh thermal environments. Calibration of these sensors is accomplished through the one-probe, two-probe and total surface heat transfer calibration integral equation formulations. The one-probe calibration integral equation method (CIEM) can be used to predict the surface thermal boundary conditions of a field test using the in-depth TC temperature from that test and data from a calibration test which consists of measured surface boundary conditions and data from the same in-depth TC. The calibration integral equation has the form of a Volterra integral equation which is ill-posed and requires regularization to achieve a stable prediction. The one-probe calibration integral technique may only be used when the thermal boundary condition at the back surface of the sensor during the calibration and reconstruction tests is the same. The two-probe CIEM removes this restriction by requiring data from two calibration tests consisting of the measured surface thermal boundary conditions and corresponding temperature data from two in-depth TC probes. The two sets of calibration data are used to predict the surface thermal boundary conditions of a reconstruction test when the temperature data from the two in-depth TCs from the reconstruction test are provided. The calibration integral equation for determination of the total surface heat transfer uses a simplified two-dimensional geometry where three of the domain boundaries are adiabatic and the fourth is an unknown spatially variable surface heat flux. The total heat transfer into the domain is predicted using the average in-depth temperature data from a series of thermocouples located on a fixed plane parallel to the heated surface. These formulations had previously been tested using high temperature numerical data. However, it is essential to verify these methods using high temperature experimental data to demonstrate their use in physical applications. This dissertation also provided novel methods to estimate the necessary regularization parameters using the calibration data.
