Available in PDF, EPUB and Kindle. Book excerpt: A simplified heat transfer model of above and underground insulated piping systems was developed to perform iterative calculations for fluid temperatures along the entire pipe length. It is applicable to gas, liquid, fluid flow with no phase change. Spreadsheet computer programs of the model have been developed and used extensively to perform the above calculations for thermal resistance, heat loss and core fluid temperature.
Book Synopsis Thermal Transfer Calculation Methods for Insulated Underground Piping Systems and Comparisons of Results by : RN. Barton
Download or read book Thermal Transfer Calculation Methods for Insulated Underground Piping Systems and Comparisons of Results written by RN. Barton and published by . This book was released on 1980 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat-transfer calculation methods for underground piping systems differ from those for aboveground systems because of the earth envelope and its moisture content, and the thermal effect of each pipe on adjacent pipes through the earth heat sink. The calculation methods are not well known and are scattered through the literature, usually with a minimum of theory and detail. This paper reviews the choice of ground thermal conductivities and temperatures so important to accurate results. It also gives simple, once-through analytical methods for one-pipe and two-pipe systems along with basics for a currently used iterative computer program for systems of two pipes or more. The paper does not cover theory or derivations, but lists references for this information.

Book Synopsis Heat Transfer Analysis of Underground Heat Distribution Systems by : Tamami Kusuda
Download or read book Heat Transfer Analysis of Underground Heat Distribution Systems written by Tamami Kusuda and published by . This book was released on 1970 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This interim report presents the results of an in-depth heat transfer analysis of hot and cold piping systems intended for placement underground. The planning and implementation of field experiments to validate or invalidate the analysis given is currently underway. The analytic approach was to evaluate the use of steady-state heat transfer principles and then to extend these principles to include transient heat transfer effects due to initial cooling or heating and due to changing outdoor temperatures. Earth temperature and changes in earth temperature with season and depth were identified as being of prime importance. Extensive tables and graphs for use by engineers for estimation and decision were developed with the aid of the NBS computer facilities. Listings of the computer programs developed are included together with sample problems and solutions. The results allow quantitative estimates of heat transfer of insulated and uninsulated buried pipes that include a broad range of the variables of pipe fluid temperature, depth, pipe size, insulation thickness, types of insulation, thermal properties of soils, and the temperatures of the earth surrounding the pipes. Especially derived for this report were equations to accommodate systems of several pipes at different temperatures with variable spacing and complex relationships involving seasonal effects. This report contains the means for predicting the thermal performance of underground pipes containing chilled water, hot fluids, or a combination of hot and cold fluids. Experimental validation is needed.

Download or read book Thermal Analysis of Directly Buried Conduit Heat Distribution Systems written by Jin B. Fang and published by . This book was released on 1990 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The calculations of heat losses and temperature fields for directly buried conduit heat distribution systems were performed using finite element method. The finite element analysis solved two-dimensional, steady-state heat transfer problems involving two insulated parallel pipes which were encased in the same conduit casing and in separate casings, and the surrounding earth. Descriptions of the theoretical basis, computational scheme, and the data input and outputs of the developed computer programs are presented. Numerical calculations were carried out for predicting the temperature distributions within the existing high temperature hot water distribution system with two insulated pipes covered in the same metallic conduit and the surrounding soil. The predicted results generally agree with the experimental data obtained at the test site. The deviations between the predicted and measured values are found to range from 0 to 17 percent with an average of 6 percent. The rates of heat loss from two insulated pipes encased in separate conduits were calculated for different pipe sizes, fluid temperatures and insulation thicknesses. The results were compared with the predictions from a steady-state, one-dimensional radial heat conduction model. The discrepancies between finite element and radial conduction models in pipe heat loss values are discussed.
