RISApplication of the Pseudo-Spectral Time-Marching Method to Blade Response Under Upstream Perturbations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Harmonic balance (HB) or time-spectral (TS) methods are commonly used as an alternative to conventional implicit approaches to reduce the computational cost in time-periodic flows, such as turbomachinery analyses. ...
Dynamic Modeling of Solar Radiation Disturbances Based on a Biomimetic Cloud Shading Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Variation in direct solar radiation is one of the main disturbances that any solar system must handle to maintain efficiency at acceptable levels. As known, solar radiation profiles change due to earth's movements. Even ...
Disaggregation of a Tracer Cloud in Accelerating Transitional Pipe Flow
Publisher: American Society of Civil Engineers
Abstract: AbstractPrevious studies on longitudinal solute transport in a pipe during acceleration from
laminar to turbulent flow highlighted a disaggregation of the tracer cloud resulting
in two peaks occurring downstream from a ...
Maximum Power From Fluid Flow by Applying the First and Second Laws of Thermodynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The application of equilibrium thermodynamics in the study of thermal plant performance under real operating conditions is a constant challenge. In this paper, an analysis of a reservoir pressure piston working between two ...
Multivariable Closed Control Loop Methodology for Heliostat Aiming Manipulation in Solar Central Receiver Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Maintaining receiver’s thermal stresses and corrosion below the material limits are issues that need careful attention in solar thermal towers. Both depend on heliostats’ aiming points over the central receiver and available ...
