RISProjected Phase Plane Switching Curves for Vibration Reduction Filters With Negative Amplitudes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we extend the phaseplane based closedloop scheme of implementing commands shaped with vibrationreduction filters. A generalized shaping filter is considered in this work which can have negative impulse ...
Insights Into the Role of Anti-Counter Rotating Vortices on Film Cooling Efficiency
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cooling techniques are extensively employed to protect turbine components from damage due to extremely high operating temperatures. Despite the availability of multiple cooling geometries, the focus is on investigating the ...
Addressing Uncertainties in Surface Velocity Profiles and Discharge Estimation through Noncontact Methods: Case Study of Two Himalayan Rivers
Publisher: American Society of Civil Engineers
Abstract: AbstractThe study presents a new approach to analyzing the uncertainties associated with the
surface velocity profiles (SVPs) while estimating the discharge in mountainous rivers
using noncontact hydrometric techniques. ...
Minimum Move-Vibration Control for Flexible Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the rest-to-rest motion of a flexible structure with limited torque or force, it is sometimes important to control the vibrations during the move trajectory as well as at the final time. ...
Analytical Solutions of ADE with Temporal Coefficients for Continuous Source in Infinite and Semi-Infinite Media
Publisher: American Society of Civil Engineers
Abstract: In the present technical note, two aspects commonly used to obtain the analytical solution of advection–diffusion equation (ADE) with time-dependent coefficients describing solute transport due to a continuous source in ...
Transient Response of Structural Dynamic Systems with Parametric Uncertainty
Publisher: American Society of Civil Engineers
Abstract: The time-domain response of a randomly parameterized structural dynamic system is investigated with a polynomial chaos expansion approach and a stochastic Krylov subspace projection, which has been proposed here. The latter ...
AnalysisBased Key Components Selection of Latent Heat Thermal Energy Storage System Along With Active Heat Transfer Enhancement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Energy storage is an effective approach to bridging the gap between energy supply and demand created due to the sporadic nature of solar energy. Thermal performance enhancement is a key research subject for effective energy ...
Effect of Perforation on Vortex Characteristics of a Microvortex Generator Mounted on a Flat Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of perforation on the characteristics of the downstream vortex of a microvortex generator (MVG) mounted on a flat plate, are numerically investigated in this paper. A single rectangular MVG with circular and ...
