Title: Predictions of Necking with Analytical Criteria and Comparisons with Experimental Results

Abstract

Two analytical approaches are detailed for the determination of Forming Limit Diagrams (F.L.D.) and compared with experimental results. The first one is the 'Enhanced Modified Maximum Force Criterion EMMFC' and the second one is the 'Through-Thickness Shear Instability Criterion TTSIC'. The criteria are both written in an intrinsic analytical form and are applicable to linear and non-linear strain paths as it occurs in any FEM codes for sheet-metal forming simulation. Finally, the two methods are complementary depending on the nature of failure and the predicted curves are in reasonable agreement with the trend of experimental results for a wide range of materials.

  • Cavity solar receivers are generally believed to have higher thermal efficiencies than external receivers due to reduced losses. A simple analytical model was presented by the author which indicated that the ability to heat the air inside the cavity often controls the convective loss from cavity receivers. Thus, if the receiver contains a large amount of inactive hot wall area, it can experience a large convective loss. Excellent experimental data from a variety of cavity configurations and orientations have recently become available. These data provided a means of testing and refining the analytical model. In this manuscript, a brief descriptionmore » of the refined model is presented. Emphasis is placed on using available experimental evidence to substantiate the hypothesized mechanisms and assumptions. Detailed comparisons are given between analytical predictions and experimental results. Excellent agreement is obtained, and the important mechanisms are more clearly delineated.« less

  • At Argonne National Laboratory (ANL), the fouling of convective heat transfer surfaces of an MHD steam plant by seed and coal ash was investigated in experiments conducted in the Fossil Energy Users Laboratory (FEUL). Data on vapor and particle deposition rates, heat transfer rates, and deposit characteristics were obtained. The test results were interpreted by an analytical model that calculated the heat transfer rates and the deposition rates of seed and ash at the surfaces of a tube bank. In this paper, the test results and the analytical model are described, and the interpretation of the test data by themore » model is discussed.« less
  • High-density-plasma deposition of SiO{sub 2} is an important process in integrated circuit manufacturing. A list of gas-phase and surface reactions has been compiled for modeling plasma-enhanced chemical vapor deposition of SiO{sub 2} from SiH{sub 4}, O{sub 2}, and Ar gas mixtures in high-density-plasma reactors. The gas-phase reactions include electron impact, neutral{endash}neutral, ion{endash}ion, and ion{endash}neutral reactions. The surface reactions and deposition mechanism is based on insights gained from attenuated total reflection Fourier transform infrared spectroscopy experiments and includes radical adsorption onto the SiO{sub 2} surface, ion-enhanced desorption from the surface layer, radical abstractions, as well as direct ion-energy-dependent sputtering of themore » oxide film. A well-mixed reactor model that consists of mass and energy conservation equations averaged across the reactor volume was used to model three different kinds of high-density plasma deposition chambers. Experimental measurements of total ion densities, relative radical densities, and net deposition rate, as functions of plasma operating conditions, have been compared to model predictions. The results show good quantitative agreement between model predictions and experimental measurements. The compiled reaction set and surface reaction network description was thus validated and can be employed in more sophisticated two- or three-dimensional plasma simulations. {copyright} {ital 1998 American Vacuum Society.}« less
  • This paper reports that the Oconee Nuclear Station, like most nuclear facilities, monitors its personnel with two types of dosimeters: a thermoluminescent dosimeter (TLD), which is normally used for determining the official dose equivalent, and a pocket ionization chamber (PIC), which is used to estimate exposure for control purposes. At Oconee, the results obtained from the two types of dosimeters are compared on a monthly basis as a part of the routine exchange and processing of worker TLDs. Each worker's TLD result is compared to the sum of the PIC dose estimates for the month that the TLD was used.more » The TLD result is accepted as the official dose equivalent for the month if the comparison results are within the tolerance limits specified by the criteria. An out-of-tolerance comparison requires investigation, which consists of performance tests of the dosimetry involved and reviews of exposure records. Adjustments to a worker's official dose equivalent are made when warranted by an investigation.« less
