This book was released on 1985 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is primarily concerned with the measurement of the local radiative component of total heat transfer around a horizontal tube immersed in a large particle fluidized bed at elevated temperatures. Total heat transfer was also measured in order to assess the relative radiation contribution. The radiation measurement probe employs a silicon window mounted flush with the tube wall to transmit the radiative heat flux. A thin-film thermopile-type heat flow detector placed behind the window sensed the transmitted radiation. The thermal conductivity of silicon is sufficiently large to prevent the conduction error (less than 3%) resulting from the convective component of heat transfer. Silicon also has a wide spectral transmission wave band extending from 1.3 um to 12.0 um. The total heat transfer probe uses a similar heat flow detector bonded to the tube wall and covered tightly with a stainless steel foil to protect the detector against abrasion. The radiation probe was calibrated using a narrow-angle blackbody source. The purpose of the calibration was to establish the relation between the heat flux detected by the radiation probe and the incident radiative flux to the tube wall. This relation was found to be linear and insensitive to the tube wall temperature variations encountered in this study. The instrument has been used to measure local radiative and total heat transfer at 0, 45, 90, 135, and 180 degree positions around a horizontal tube immersed in a fluidized bed. Measurements were obtained at bed temperatures of 812 K and 1050 K with 2.14 mm and 3.23 mm mean diameter particles at gas velocities up to two times the minimum fluidization velocity. A sharp increase was noted for spatial average radiative, total and convective heat transfer coefficients when the gas velocity exceeded the minimum fluidizing velocity. Generally, these coefficients showed little variation with further increase in gas flow rate. The radiative heat transfer coefficient was increased with an increase in particle size and bed temperature, the latter having a much more pronounced effect, as expected. The radiation contribution to overall heat transfer was found to increase from 9% to 15% for 3.23 mm particles and from 8% to 13% for 2.14 mm particles when the bed temperature was elevated from 812 K to 1050 K at the optimum gas velocity (maximum total heat transfer). Finally, fast sampling rate (25 samples/sec) data were obtained using the radiation probe with a measured response time of about 120 msec. This data was treated as instantaneous and an attempt was made to obtain hydrodynamic parameters such as emulsion residence time and bubble contact fraction. However, this analysis did not yield satisfactory results.

Book excerpt: Thermal Radiation: An Introduction is a complete textbook for a one-semester introductory graduate course on radiative energy transfer. It bridges the gap between a basic introduction and comprehensive coverage of thermal radiation, focusing on insight into radiative transfer as practiced by engineers. Covering radiative transfer among surfaces, with an introduction to the effects of participating media between surfaces, the book includes surface and medium property characteristics and solutions to the radiative transfer equation in simple geometries. • Tailored and organized specifically to suit a one-semester graduate course in radiative heat transfer. • Emphasis is placed on insight into radiative transfer as practiced by engineers. • Discusses how radiation is incorporated into finite element analysis (FEA) codes. The textbook is intended for instructors and graduate students in a first-year course on radiative heat transfer or advanced heat transfer. Supplementary resources for students and instructors are available online.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluoride Salt-Cooled High-Temperature Reactors (FHRs) use high Prandtl high-temperature FLiBe (2LiF-BeF2) salt to transport energy. The salt coolant has a freezing point of 459 °C and a boiling point of 1400 °C at atmospheric pressure. Flow perturbations due to overcooling transients may affect the performance and stability behavior of natural circulation systems in FHRs. Furthermore, due to the high-temperature operation (500-700 °C) and the near-to-mid infrared optical transparency nature of the salt coolant, radiative heat transfer in participating media can affect the temperature distribution. In this work, the stability behavior of natural circulation systems using FLiBe coolant is investigated. A new 1-D linear stability analysis that accounts for salt freezing is developed, and the Nyquist Stability Criterion is employed to estimate the stability boundary on a Grashof versus Reynolds plot. The loop response to the disturbances caused by the freezing of salt in the coldest heat exchanger is expressed in the form of pressure drop due to pipe contraction. The simulations have shown that the system is more likely to become unstable as the Reynolds number increases. In the event of freezing of salt, the model predicted that the stability boundary is dependent on the Biot number of the frozen layer; however, the increase in friction losses has a stabilizing effect on the natural circulation flow. Additionally, the contribution of radiative heat transfer (RHT) to conductive-convective heat transfer, for FLiBe molten salt, is investigated computationally and the Nusselt ratio, Nu_total/Nu_(no-rad), was implemented to quantify the magnitude of these RHT effects. Under forced convection, Nu_total/Nu_(no-rad) reaches a peak value of 1.76 at Ï4_D=4, and is less than 1.1 for Ï4_D0́−0.1 and Ï4_D60. Under aiding-flow mixed convection, Nu_total/Nu_(no-rad) reaches a peak of 1.34 at Ï4_D=4.2 and is less than 1.1 for Ï4_D0́−0.4 and Ï4_D36. Under opposing-flow mixed convection, Nu_total/Nu_(no-rad) reaches a peak of 1.81 at Ï4_D=4.2 and is less than 1.1 for Ï4_D0́−0.2 and Ï4_D50. The influence of wall emissivity and pipe diameter is also discussed in this work. Overall, for a vertical heated tube, radiative heat transfer effects lead to enhancement of heat transfer by as high as a factor of two, and they depend on the optical thickness of the flow, mixed convection environment (Gr\/Re^2 and direction of flow relative to gravity), surface emissivity, and entrance effects. Lastly, a multi-band thermal radiation method was developed that is capable of capturing the spectral dependence of the absorption coefficient for FLiBe at a reasonable computational cost. The method was deployed to investigate the thermal performance of the UW natural circulation FLiBe loop under various power levels and operating conditions. The numerical results were interpreted and analyzed against experimental data to assess the ability of the CFD model to predict the flow and heat transfer behavior of the salt and to evaluate the impact of radiative heat transfer. The CFD simulations predicted that thermal radiation enhances the overall heat transfer by more than 18% and that RHT acts to reduce wall temperature while improving temperature uniformity within the salt.

Available in PDF, EPUB and Kindle. Book excerpt: In recent times several articles have been published in which the radiative heat flow is computed between plane parallel, plates with anisotropically scattering atmosphere. An involved analytical treatment employing matrix calculus and a computer program as long and involved as the mathematical analysis was used. Work presented herein indicates that a usable solution to the problem can be obtained by simple iteration of the set of equations which result from approximation of the equation of radiation transfer. The iteration worked perfectly, the computer program is simple and short, and the method can accommodate the same, if not more, parameter variations than the more analytical treatments.
