Abstract: For model tests on cavitation inception, the knowledge of the size distribution and frequency of occurrence of free nuclei is important. For this reason, an optical measuring method was developed ...

Abstract: A simulation technique, applicable to any spatial mechanism having lower pairs, is presented. A detailed description of the required electronic analog-computer circuitry is given. The geometrical ...

Abstract: A method for the simulation of mechanisms on the electronic analog computer has been developed. In this paper a detailed discussion of the accuracy of the simulation is presented. Particular ...

Abstract: Rules are given which allow the center and circle point curves of Burmester theory to be sketched rapidly and with reasonable accuracy. It is anticipated that these rules will be useful in ...

Abstract: The validity of the hydrostatic approximation is examined for use in predicting the dynamics of topographically generated atmospheric gravity waves (lee waves) propagating in an atmosphere with realistic wind shear. To ...

Abstract: A theory of the impact or collision of two rigid bodies, taking account of friction, is presented. It determines how the direction of sliding varies during the impact, which must be known ...

Abstract: It is observed that the equations of motion governing finite elastic deformation are linear if and only if the Piola-Kirchhoff stress tensor is linear in the deformation gradient. Then the ...

Abstract: A method for calculating the stress distribution in a narrow region of an elastic plate is presented. It consists in treating the narrow region by beam theory, treating the rest of the plate ...

Abstract: Full-scale vibro-acoustical diagnostic measurements of cavitation in four Francis 6 MW double runner turbines were performed. Two types of sensors were used—a hydrophone sensing waterborne noise ...
