The Effect of Plenum Volume on the Test Section Flow Characteristics of a Perforated Wall Transonic Tunnel by C. F. Anderson,A. Anderson,O. P. Credle Pdf

Tests were conducted in the Aerodynamic Wind Tunnel (1T) of the Propulsion Wind Tunnel Facility to determine the effects of test section plenum chamber volume on the centerline Mach number distributions, wave-cancellation properties of perforated walls, model force data, and tunnel acoustics at Mach numbers from 0.6 to 1.3. Results were obtained with plenum chambers of four different sizes at plenum-to-test section volume ratios between 8.3 and 0.8. Reducing plenum volume produced no measurable effect at Mach numbers below 0.95. At Mach numbers above 0.95, decreasing the plenum volume increased the internal plenum losses, increased the plenum suction requirements, and increased the centerline Mach number deviations; however, the Mach number deviations were small at Mach numbers below 1.15. Reducing the plenum volume also produced a small increase in the effective wall porosity but had no measurable effect on measured model forces except to increase the forebody drag coefficient at Mach numbers above 1.05. Changes in the plenum volume had no significant effect on tunnel acoustics. (Author).

Between Two Plenums by Ellis Joffe Pdf

The origins of the Cultural Revolution are still shrouded in uncertainty. Crucial questions either remain unanswered or have been given answers which derive from conflicting interpretations. To what period can the direct origins of the Cultural Revolution be traced? What issues, if any, divided the leadership, and how deep were these divisions? What was the state of power relations and what was Mao’s position? Why did developments in the period preceding the Cultural Revolution reach a climax in such a convulsion? Between Two Plenums examines these questions as they apply to the years 1959–1962. At base, the perspective of pre-Cultural Revolution politics adopted therein is that of “conflict” rather than “consensus.” From this vantage point, the Eighth and Tenth Plenums loom in retrospect as important watersheds in the development of the intraleadership conflict which culminated in the great upheaval.

Model Specification for Tunnelling by British Tunnelling Society,Institution of Civil Engineers (Great Britain) Pdf

This reference aims to establish a common standars for the design and construction of tunnelling in the UK. With the minimum of modification the specification is also suitable for international use. It includes recent legislation, and indicates minimum standards for materials and workmanship, and has been written to be used as a contract specification on its own, or in conjunction with other standard specifications on multi-disciplinary projects. Drawing heavily on the practical experience of both corporate and individual members of the British Tunnelling Society, this document provides a sound basis for specifying tunnelling design and construction.

Industrial Process Plant Construction Estimating and Man-Hour Analysis by Kenneth Storm Pdf

Industrial Process Plant Construction Estimating and Man-Hour Analysis focuses on industrial process plants and enables the estimator to apply statistical applications, estimate data tables, and estimate sheets to use methods for collecting, organizing, summarizing, presenting, and analyzing historical man-hour data. The book begins with an introduction devoted to labor, productivity measurement, collection of historical data, verification of data, estimating methods, and factors affecting construction labor productivity and impacts of data. It goes on to explore construction statistics and mathematical spreadsheets, followed by detailed scopes of work ranging from coal-fired power plants to oil refineries and solar plants, among others. Man-hour schedules based on historical data collected from past installations in industrial process plants are also included as well as a detailed glossary, Excel and mathematical formulas, area and volume formulas, metric/standard conversions, and boiler man-hour tables. Industrial Process Plant Construction Estimating and Man-Hour Analysis aids industrial project managers, estimators, and engineers with the level of detail and practical utility for today's industrial operations and is an ideal resource for those involved in engineering, technology, or construction estimation. Identify quantity differences with the comparison method and eliminate impacts between proposed and previously installed equipment Understand how to implement statistical and estimating methods, scopes of work, man-hour tables and estimate sheets to produce direct craft man-hour estimates, RFPs, and field change orders Set up and utilize Excel templates to automate statistical functions that will perform mathematical applications key to process plant construction
