An optimization framework development for organic rankine cycle driven by waste heat recovery: Based on the radial-inflow turbine

open access: yesCase Studies in Thermal Engineering, 2022
As the crucial component of the ORC-WHR system, the turbine not only directly influences the system's thermodynamic performance but also dominates the investment cost of ORC-WHR components.

On the Structure of the Power Graph and the Enhanced Power Graph of a Group

open access: yesThe Electronic Journal of Combinatorics, 2017
Let $G$ be a group‎. ‎The power graph of $G$ is a graph with the vertex‎ ‎set $G$‎, ‎having an edge between two elements whenever one is a power of the other‎. ‎We characterize nilpotent groups whose power graphs have finite independence number‎. ‎For a bounded exponent group‎, ‎we prove its power graph is a perfect graph and we determine‎ ‎its clique ...

Power Output Enhancement of a Ducted Wind Turbine by Stabilizing Vortices around the Duct

open access: yesEnergies, 2019
A brimmed-diffuser augmented turbine (called a wind lens turbine: WLT) actively uses vortices around the brim to enhance its power output. However, the vortices are usually unstable and asymmetric.

Enhancing the cosmic shear power spectrum [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
Applying a transformation to a non-Gaussian field can enhance the information content of the resulting power spectrum, by reducing the correlations between Fourier modes. In the context of weak gravitational lensing, it has been shown that this gain in information content is significantly compromised by the presence of shape noise. We apply clipping to

Comparative study on natural convection melting in square cavity using lattice Boltzmann method

open access: yesResults in Physics, 2020
The phase change process is of significant importance in the application of phase change material (PCM). In this paper, the natural convection melting in a square cavity was investigated and the enthalpy-based lattice Boltzmann model (TLBM) combined with
