A Book Review from FSReview Website In the late 1800's, early 1900's, there were a variety of secret /occult societies in Germany, the main ones being, The Bavarian Illuminati, The Freemasons, The Rosicrucians, The Thule Society and The Vril Society. Each of these five societies, although based in secrecy and mysticism, had its role and function.
Cordier diagram can be used to determine specific speed and impeller tip diameter . Accordingly solidity ratio and hub-tip ratio (range 0.3-0.7) can be adjusted. Solidity ratio …
The design of high-efficiency fans is often based on the experience of the designer. In order to determine its main dimensions, fan designers use the Cordier diagram. For a given operating point (i.e. flowrate and pressure, and a rotating speed), the optimum diameter of high-efficiency fans can be found in the Cordier diagram. The Cordier diagram is an empirical diagram based on measurements.

Jul 09, 2013· The paper provides a theoretical interpretation of the CORDIER-lines for squirrel-cage and cross-flow fans, since they differ considerably from the classical relationship. Based on velocity triangles and energy transfer, CORDIER-line of squirrel-cage fans depends on absolute inlet flow angle, relative exit flow angle, rotor inlet to exit ...

They are bound together with the 3rd printed book of this work and the "Manuel pratique d'Equitation", never published, and a personal letter from Cordier to the "Messieurs ...
Cordier-diagram and its asymptotes are discussed. The technological progress causes that nowadays machines of high specific speed and hence small specific diameter, like Kaplan turbines, can be used, delivering the same power as the antiquated machines of low specific speed, like water wheels, ...
The Cordier diagram represents a universally valid relationship between flow rate, pressure drop, runner diameter and runner speed of a fluid-flow machine. Later contributions to Cordier's theory suggest that there is not only a single Cordier curve, but rather a set of curves at which all design points of a fluid-flow machine are located ...

Publisher Summary. This chapter introduces the book on fluid mechanics and the thermodynamics of turbomachines. The book examines, through the laws of fluid mechanics and thermodynamics, the means by which the energy transfer is achieved in the chief types of turbomachines, together with the differing behavior of individual types in their operations.

Sep 18, 2014· Therefore, the performance curve can be transformed to the Cordier-diagram to predict the relationship between speed number and diameter number. It is shown that the Cordier-line depends mainly on velocity triangles and the common argument of high efficiency, claimed in the majority of the literature, plays only a secondary role.
