An Application of the Weis-Fogh Mechanism to Ship Propulsion
(The American Society of Mechanical Engineers (ASME), 1987)A mechanism of hovering flight of small insects which is called the Weis-Fogh mechanism is applied to ship propulsion. A model of the propulsion mechanism is proposed, which is based on a ... -
An Example of Transient Laminar Countercurrent Flow
(The American Society of Mechanical Engineers (ASME), 1987)This paper presents a numerical and experimental study of transient laminar countercurrent flow in which the pressure gradient is time-dependent. An explicit finite-difference scheme is used to ... -
Resistance to the Flow of Fluids Through Simple and Complex Porous Media Whose Matrices Are Composed of Randomly Packed Spheres
(The American Society of Mechanical Engineers (ASME), 1987)Experimental data relating to the flow of fluids through simple and complex porous media whose matrices are composed of randomly packed spheres have been obtained. In this context the term ... -
Flow Characteristics of Swirling Coaxial Jets From Divergent Nozzles
(The American Society of Mechanical Engineers (ASME), 1987)The aerodynamic characteristics of free, swirling, coaxial jets issuing from an air model of a typical burner for pulverized bituminous coal have been studied. Detailed measurements of mean ... -
Added Mass and Damping for Cylinder Vibrations Within a Confined Fluid Using Deforming Finite Elements
(The American Society of Mechanical Engineers (ASME), 1987)Added mass and fluid damping coefficients for vibrations of an inner cylinder that is enclosed by a concentric outer cylinder are determined by finite element analysis of the unsteady, laminar, ... -
Spray Photographs, Poppet Lift, and Injection Pressure of an Oscillating Poppet Injector
(The American Society of Mechanical Engineers (ASME), 1987)Sprays from an injector with a conical oscillating poppet and supplied with fuel at injection rates similar to those used in direct-injection stratified-charge engines have been characterized. ... -
Compressor Erosion and Performance Deterioration
(The American Society of Mechanical Engineers (ASME), 1987)Aircraft engines operating in areas where the atmosphere is polluted by small solid particles are typical examples of jet engines operating under hostile atmospheric environment. The particles ... -
Slip Factors of Centrifugal Slurry Pumps
(The American Society of Mechanical Engineers (ASME), 1987)Experiments have been carried out in order to determine the effects on slip factor due to the various parameters affecting the performance characteristics of a centrifugal slurry pump. The ... -
Friction and Heat Transfer Measurements for Clay Suspensions With Polymer Additives
(The American Society of Mechanical Engineers (ASME), 1987)Local heat transfer and friction coefficients were measured in a circular tube for suspensions of bentonite and for a combination of bentonite and polyacrylamide in water. Both the entrance and ... -
Studies of the Configuration and Performance of Annular Type Jet Pumps
(The American Society of Mechanical Engineers (ASME), 1987)In this paper, we investigated experimentally the relation between configuration and performance of the annular type jet pump and compared it with that of the central jet type. Twenty-five ... -
