RISImproving the Aero-Thermal Characteristics of Turbomachinery Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents the application of an optimization procedure to the aero-thermal design of high performance turbomachinery cascades. The blade profiles are parameterized with third-order Bezier ...
Forced Oscillations in a Two-Layer Fluid of Finite Depth
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An initial value investigation is made of the development of surface and internal wave motions generated by an oscillatory pressure distribution on the surface of a fluid that is composed of ...
Resistance Reduction in Pulsating Turbulent Pipe Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper describes the effects of forced harmonic oscillations of fixed frequency and amplitudes in the range Λ=Um/Ub=1–11 on the characteristics of a turbulent pipe flow with a bulk Reynolds ...
Synthesis of a Pattern Generation Mechanism for Gait Rehabilitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gait training is a major part of neurological rehabilitation. Robotic gait training systems provide paraplegic patients with consistent, labor-saving, and adjustable physical therapy over traditional ...
Experimental and Theoretical Studies on the Nonlinear Characteristics of Soil-Pile Systems under Coupled Vibrations
Publisher: American Society of Civil Engineers
Abstract: This study includes the determination of soil-pile separation lengths and frequency-amplitude responses of single and group piles under rotating machine-induced coupled (horizontal and rocking) vibrations by experimental ...
Irradiation Damage Evolution Dependence on Misorientation Angle for Σ 5 Grain Boundary of Nb: An Atomistic Simulation-Based Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Niobium as refractory element holds ability to arrest the primary radiation damage in reactor's fissionable conditions and can withstand high-temperature applications. We have inclined the investigation of irradiated Nb Σ ...
Comparative Assessment of Dynamic Behavior of Vertical and Batter Pile Groups under Horizontal Excitation
Publisher: ASCE
Abstract: This paper aims to compare the dynamic response of the vertical pile group (VPG) and batter pile group (BPG) subjected to machine-induced-type loading. For this purpose, an experimental investigation is carried out on a 2 ...
Shaking Table Tests to Evaluate the Seismic Performance of Soil Nailing Stabilized Embankments
Publisher: ASCE
Abstract: A series of shaking table tests will be carried out on 0.4 m high instrumented soil nailed embankments. The important parameters considered in this study consist of a combination of three different slope angles (β = 30°, ...
Nonlinear Dynamic Response of Piles under Horizontal Excitation
Publisher: American Society of Civil Engineers
Abstract: This paper presents test results from cast-in situ reinforced concrete single and group piles subjected to strong horizontal excitation. The tests were conducted for different eccentric moments simulating different excitation ...
