The Concept of Segmented Wind Turbine Blades: A Review
Energies, 2017 There is a trend to increase the length of wind turbine blades in an effort to reduce the cost of energy (COE). This causes manufacturing and transportation issues, which have given rise to the concept of segmented wind turbine blades.

8-stroke low heat rejection engine
Energy Reports, 2022 In a combustion engine, 25% of the energy present in the fuel is wasted as heat; this heat is dissipated to avoid overheating and prevent damages. This article presented a simulation work developed to study an internal combustion engine with a low heat ...

Hybrid RANS/LES computation of plane impinging jet flow
Archives of Mechanics, 2011 Flow characteristics are presented of simulation results of plane impinging jets at high nozzle-plate distances, with two k-ω based hybrid RANS/LES (Reynolds Averaged Navier–Stokes/Large–Eddy Simulation) models and a k-ω RANS model. The first hybrid RANS/

Fire-Safe Hierarchical Solid Polymer Electrolytes Enabled by Dual-Functional Microcapsules for Lithium Metal Batteries. [PDF]
Adv Sci (Weinh)Dual‐functional fire‐safe microcapsules are integrated into hierarchical solid polymer electrolytes to provide sequential protection against thermal abuse. The ammonium hydrogen phytate‐modified shell forms a protective char barrier, while the thermally triggered release of perfluoro(2‐methyl‐3‐pentanone) actively suppresses combustion, enabling safer ...

Heat of combustion and heat of formation of aluminum carbide
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1964 The heat of combustion of aluminum carbide (A14C3) in oxygen was measured by means of bomb calorimetry. The solid product of the combustion consisted of alpha aluminum oxide and another crystalline form of alumina, which was characterized as delta alumina. The heats of combustion were corrected for the formation of the delta aluminum oxide. The results,

Comparison of Moving Boundary and Finite-Volume Heat Exchanger Models in the Modelica Language
Energies, 2016 When modeling low capacity energy systems, such as a small size (5–150 kWel) organic Rankine cycle unit, the governing dynamics are mainly concentrated in the heat exchangers. As a consequence, the accuracy and simulation speed of the higher level system
