The increasing share of renewables in energy systems requires storage technologies to handle intermittent sources and varying sinks. Liquid air (LAES) is a promising technology since it has high density not geographically constrained. A relatively round-trip efficiency (RTE) obtained by using hot cold recovery cycles the LAES. In this work, seven cases related different are optimized compared f...

Nowadays, energy consumption management is a vital strategy for societies to optimize energy consumption. Considering the widespread functions of electrical energy in human lives,a high proportion of consumption management procedures deals with the management of electrical energy consumption. It is important to study the state of electrical energy and provide managerial and optimal management s...

An increase in fossil fuel consumption has significantly increased the concentration of greenhouse gases (GHGs). Waste energy recovery can reduce GHGs by reducing fossil fuel consumption. In the FCC unit in refineries, the catalyst is continuously regenerated by burning off the deposited coke with air and a large flux of waste gas with high temperature is generated which is vented into the atmo...

OBJECTIVE Pathological gaits have been shown to limit transfer between potential (PE) and kinetic (KE) energy during walking, which can increase locomotor costs. The purpose of this study was to examine whether energy exchange would be limited in people with knee osteoarthritis (OA). METHODS Ground reaction forces during walking were collected from 93 subjects with symptomatic knee OA (self-s...

A superconducting electron linac together with an energy-recovery system, which has been demonstrated as a useful driver for high-power IR-FELs, seems to be an attractive device for a future X-ray FEL facility as well, because the energy-recovery enable one to reduce the RF generator power required for the operation and also reduce the radiation from the beam dump. Automatic cancellation of bea...

The energy demand in India is increasing substantially and the energy supply is not in pace with demand. The recovery of energy from waste material is one of the best methods to tackle the energy crisis. The potential for recovery of energy from urban waste is high in Maharashtra followed by Uttar Pradesh, Tamil Nadu and West Bengal. In this paper, anaerobic digestion method is used to find the...

The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...
