Fluidelastic Instability in Shell and Tube Heat Exchangers: A Framework for a Prediction Method

Description: A framework for a method to predict fluid-elastic instability in heat exchanger tube bundles is presented. The method relies on a three-dimensional, cylindrical coordinate, thermal-hydraulic analysis code to obtain a representation of the three-dimensional flow distribution within the heat exchanger. With this information, local cross-flow velocities corresponding to each tube in the exchanger are obtained by interpolation and resultant cross-flow velocity distributions are computed. With a kno… more

An LMA-Based Theorem Prover

Description: We describe here a theorem prover constructed from the facilities provided by Logic Machine Architecture (LMA). This program is not part of LMA itself, but illustrates the level of inference-based system which can be constructed from the LMA package of tools. It is a clause-based theorem prover supporting a wide variety of techniques which have proven valuable over the years in a long-running automated deduction research project. In addition, it is designed to present a convenient, interactive … more

Physics Division Annual Review: 1 April 1981-31 March 1982

Description: The research program in nuclear physics in the Argonne Physics Division contributes to most of the major questions in this scientific discipline. The development of the superconducting rf linac technology has led to the ATLAS project now under construction, and is the major focus of the effort in heavy-ion research. The investigation of pion interactions in nuclei using the LAMPF facility helps delineate the dominant aspects of pion propagation and interactions in nuclei. Experiments on the wea… more

Randomly Generated Test Problems for Positive Definite Quadratic Programming

Description: A procedure is described for randomly generating positive definite quadratic programming test problems. The test problems are constructed in the form of linear least squares problems subject to linear constraints. The probability measure for the problems so generated is invariant under orthogonal transformations. The procedure allows the user to specify the size of the least squares problem (number of unknown parameters, number of observations, and number of constraints); the relative magnitude… more

Stability of Tube Rows in Crossflow

Description: A mathematical model for the instability of tube rows subjected to crossflow is examined. The theoretical model, based on the fluid-force data for a pitch-to-diameter ratio of 1.33, provides additional insight into the instability phenomenon. Tests are also conducted for three sets of tube rows. The effects of mass ratio, tube pitch, damping, detuning and finned tubes are investigated. Theoretical results and experimental data are in good agreement.

DYNAPCON: A Computer Code for Dynamic Analysis of Prestressed Concrete Structures

Description: A finite element computer code for the transient analysis of prestressed concrete reactor vessels (PCRVs) for LMFBR containment is described. The method assumes rotational symmetry of the structure. Time integration is by an explicit method. The quasistatic prestressing operation of the PCRV model is performed by a dynamic relaxation technique. The material model accounts for the crushing and tensile cracking in arbitrary direction in concrete and the elastic-plastic behavior of reinforcing ste… more

Fuel-Motion Diagnostics and Cineradiography

Description: Nuclear and non-nuclear applications of cineradiography are reviewed, with emphasis on diagnostic instrumentation for in-pile transient-reactor safety testing of nuclear fuel motion. The primary instrument for this purpose has been the fast-neutron hodoscope, which has achieved quantitative monitoring of time, location, mass, and velocity of fuel movement under the difficult conditions associated with transient-reactor experiments. Alternative diagnostic devices that have been developed have no… more

Ice Production and Storage for Seasonal Applications Utilizing Heat Pipe Technology

Description: This report presents the results of the analytical and experimental work of the application of heat pipes to the production of winter ice for seasonal cooling applications. This program consisted of two major subtasks. The first subtask was to develop theoretical models of heat-pipe and system performance. The second subtask was to perform laboratory experiments on full-scale units to measure performance as functions of ambient conditions, and to make design variations in response to experiment… more

Light-Water-Reactor Fission-Product Data Assessment

Description: This assessment seeks (1) to determine the most probable chemical compounds formed between fission products and actinides in urania fuels under normal and accident conditions and (2) to identify gaps in knowledge of these fission-product compounds. The ultimate goal of this effort is to develop predictive capability about the behavior of fission products under normal and accident conditions. The relevant thermochemical data have been organized by compound type, the chemical stability of resulta… more

The Measurement of Leaching from Simulated Nuclear-Waste Glass Using Radiotracers

Description: The use of radiotracer spiking as a method of measuring the leaching from simulated nuclear-waste glass is shown to give results comparable with other analytical detection methods. The leaching behavior of strontium-85, ruthenium-106, barium-133, cesium-137, cerium-141, europium-152, and other isotopes is measured for several defense waste glasses. These tests show that radiotracer spiking is a sensitive, multi-element technique that can provide leaching data, for actual waste elements, that ar… more
