The response of soil subjected to thermal cyclic loading plays an important role in certain engineering applications, such as high-level nuclear waste disposal, heat storage systems, CO2 sequestration plant and energy geostructures. For instance, energy ge ...
Solar-driven non-stoichiometric thermochemical redox cycling of ceria for the conversion of solar energy into fuels shows promise in achieving high solar-to-fuel efficiency. This efficiency is significantly affected by the operating conditions, e.g. redox ...
A decentralized adaptive solar air conditioning system is presented, which contains usual air-conditioning equipment and a new module, designed with a honeycomb structure, containing phase change material for latent thermal cold and hot energy storage. Hea ...
The world energy consumption has dramatically increased since the end of the World War II. The main share of this energy comes from fossil fuel combustion. The worldwide domestic sector consumes about 30% of the global energy supply and the biggest share o ...
The Lucerne University of Applied Sciences has been analysing and monitoring the low- temperature district heating and cooling network (LTN) “Suurstoffi” since 2012. The analysis showed that heating demand was twice as high as expected. On the other hand, ...
The operation of energy pile in summer can expel excessive heat of the buildings into the ground by the use of a heat pump. Despite of having been implemented for decades, the design of energy pile still relies heavily on empiricism as there is still limit ...
Distributed power generation and cogeneration is an attractive way toward a more rational conversion of fuel and biofuel. The fuel cell-gas turbine hybrid cycles are emerging as the most promising candidates to achieve distributed generation with comparabl ...
This paper presents the experimental investigation of a concept of Thermally Driven Heat Pump (TDHP), based on the coupling of a vapor compression heat pump cycle and an Organic Rankine Cycle (ORC). The studied concept uses a single stage centrifugal compr ...
We seek to study numerically two-phase flow phenomena with phase change through the finite-element method (FEM) and the arbitrary Lagrangian-Eulerian (ALE) framework. This method is based on the so-called one-fluid formulation; thus, only one set of equati ...
This paper investigates the energy efficiency improvement of an industrial site through thermodynamic analysis of distillation columns together with the total site integration (TSI). Unlike the existing methods which consider the distillation unit exclusiv ...
