RISA Novel Explicit Equation for Friction Factor in Smooth and Rough Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we propose a novel explicit equation for friction factor, which is valid for both smooth and rough wall turbulent flows in pipes and channels. The form of the proposed equation ...
Closure to “Discussion: ‘A Novel Explicit Equation for Friction Factor in Smooth and Rough Pipes’ ” (2011, ASME J. Fluids Eng., 133, p. 015501)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The discussion made by Tajadura and Gonzales (1) necessitates the clarification of the comments about our paper (2). The same notation and comment numbers are used here, to respond to the ...
Optimal Synthesis of Mechanisms for Path Generation Using Fourier Descriptors and Global Search Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Generally, success in synthesis of mechanisms for path generation is limited to finding a reasonable local optima at best in spite of a very good initial guess. The most widely used Structural ...
Alternative Approach for Predicting the Phase Angle Characteristics of Asphalt Concrete Mixtures Based on Recurrent Neural Networks
Publisher: ASCE
Abstract: Laboratory performance testing of the phase angle of asphalt concrete (AC) mixtures is often expensive and requires enormous human effort and time. To circumvent this problem, several regression-based methods have been ...
Improving Efficiency of the Tip Speed Ratio-MPPT Method for Wind Energy Systems by Using an Integral Sliding Mode Voltage Regulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper aims to increase the efficiency of the maximum power point tracking (MPPT) methods by using an integral sliding mode voltage regulator (ISMVR). The ISMVR is applied to one of the frequently used MPPT methods ...
Flexural Analysis of Functionally Graded CNT-Reinforced Doubly Curved Singly Ruled Composite Truncated Cone
Publisher: American Society of Civil Engineers
Abstract: The flexural analysis of functionally graded carbon nanotube (CNT)-reinforced doubly curved singly ruled composite truncated cone is studied. The mathematical model contains the expansion of Taylor’s series up to third ...
Scour around an Erodible Abutment with Riprap Apron over Time
Publisher: American Society of Civil Engineers
Abstract: Acknowledged as a significant cause of bridge failure is abutment scour around bridge foundations. Because of the complexity of flow structures and scour mechanisms around an abutment, abutment scour remains the focus of ...

State and Rate Dependent Friction Laws for Modeling High-Speed Frictional Slip at Metal-on-Metal Interfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: , results of plate-impact pressure-shear friction experiments were conducted by Irfan in 1998 and Irfan and Prakash in 2000 using a Ti6Al4V and Carpenter Hampden tool-steel tribo pair are employed. In these experiments high...
The Effect of Inlet Parameters on Fluid Flow and Cell Performance at Cathode of a Proton Exchange Membrane Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the fluid flow and cell performance in cathode side of a proton exchange membrane (PEM) fuel cell were numerically analyzed. The problem domain consists of cathode gas channel, ...
