A Comparison of Single-Entry and Multiple-Entry Casing Impingement Manifolds for Active Thermal Tip Clearance Control

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2021
In this paper, we compare using computational fluid dynamics the aero-thermal performance of two candidate casing manifolds for supplying an impingement-actuated active tip clearance control system for an aero-engine high-pressure turbine.

An optimization method for uniform flow distribution in the manifold of server cabinet

open access: yesEnergy Science & Engineering, 2021
Indirect liquid cooling technique using the water‐cooled plate is an important way to cool the server. The manifold is the key component to connect the water‐cooled plates of servers.

Eigenvectors of the De-Rham Operator

open access: yesMathematics, 2023
We aim to examine the influence of the existence of a nonzero eigenvector ζ of the de-Rham operator Γ on a k-dimensional Riemannian manifold (Nk,g). If the vector ζ annihilates the de-Rham operator, such a vector field is called a de-Rham harmonic vector

3D MHD analysis of prototypical manifold for liquid metal blankets

open access: yesNuclear Fusion, 2023
The water-cooled lead lithium (WCLL) and the dual-cooled lead lithium (DCLL) are two of the breeding blanket (BB) concepts that the EUROfusion consortium is pursuing in the framework of the development of the fusion reactor industrial demonstrator DEMO ...

Dimensionality Reduction Algorithms in Machine Learning: A Theoretical and Experimental Comparison

open access: yesEngineering Proceedings, 2023
The goal of Feature Extraction Algorithms (FEAs) is to combat the dimensionality curse, which renders machine learning algorithms ineffective. The most representative FEAs are investigated conceptually and experimentally in our work.

Industrial Scale Ammonia Pipeline Transfer System and Exergy Analysis [PDF]

open access: yesKemija u Industriji, 2021
Anhydrous ammonia is the most used raw material in chemical fertilizer production. In the fertilizer production process, during the transportation of anhydrous ammonia, pressure and temperature have to be kept under control.

Symmetrifying Smart Home

open access: yesMedia Theory, 2021
This paper investigates how the current domestic application of the Internet of Things (IoT), called “smart home,” changes the socio-phenomenological meaning of place-making. It describes a smart home as a topological continuum that could unfold lots of

A neutrosophic folding on a neutrosophic fundamental group [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
In this paper, we create a new type of fundamental group called the neutrosophic fundamental group. We obtain some kinds of conditional foldings that are confined to the elements of the neutrosophic fundamental groups.

Design of a Test Section for the Experimental Investigation of the WCLL Manifold Hydraulic Features

open access: yesEnergies, 2023
A scaled-down test section representative of an Outboard Segment manifold of the Water-Cooled Lithium Lead Breeding Blanket for the European DEMO has been designed for installation and test in a high- mass flow branch of the W-HYDRA facility, under ...

Low-Rank Matrix Completion via QR-Based Retraction on Manifolds

open access: yesMathematics, 2023
Low-rank matrix completion aims to recover an unknown matrix from a subset of observed entries. In this paper, we solve the problem via optimization of the matrix manifold. Specially, we apply QR factorization to retraction during optimization. We devise
