Computational methods have been widely applied in conjugate heat transfer analysis. The very first and crucial step such research is the meshing process which consists dividing analysed geometry into numerous small control volumes (cells). In Fluid Dynamics (CFD) applications it desirable to use hexahedral cells as resulting mesh characterized by low numerical diffusion. Unfortunately generating can be a time-consuming task case of complicated - may not possible generate good quality....
Chemical Looping Combustion (CLC) is a technology that allows the separation of CO2, which generated by combustion fossil fuels. The majority process designs currently under investigation are systems coupled fluidized beds. Advances in development power generation system using CLC cannot be introduced without numerical modelling as research tool. primary and critical activity computational domain discretization. It influences diffusion well convergence model therefore overall accuracy...
Global CO2 concentration level in the air is unprecedently high and should be rapidly significantly reduced to avoid a global climate catastrophe. The work indicates possibility of quickly lowering impact changes that have already happened those we know will happen, especially terms emitted stored atmosphere, by implanting virgin ivy plant on available area walls roofs houses. proposed concept reducing from atmosphere one technologies with significant potential for implementation entirely...
Chemical looping combustion (CLC) is one of the most advanced technologies allowing for reduction in CO2 emissions during solid fuels. The modified method combines chemical with oxygen uncoupling (CLOU) and situ gasification (iG-CLC). As a result, an innovative hybrid came into existence, making above two complementary. Since complexity CLC still not sufficiently recognized, study this process practical significance. paper describes experiences modelling complex geometry equipment....
Augmentation of energy efficiency in the power generation systems can aid decarbonizing sector, which is also recognized by International Energy Agency (IEA) as a solution to attain net-zero from sector.

Long Short-Term Memory (LSTM) network algorithm was used, classified as deep learning method, to predict vapor mass quantity in bed. research used an LSTM with two hidden layers. study is composed seven inputs (absolute...
The calcium looping (CaL) process usually employs a dual-fluidized bed (DFB) solid circulating unit. In the regenerator (calcinator or calciner), decomposition of CaCO3 proceeds. To supply heat decomposition, oxyfuel combustion coal is conducted. However, since contains nitrogen, NOx formation occurs during combustion. Because fact that and destruction fuels in fluidized complex process, predictive approach emissions has not yet been sufficiently recognized, especially conditions CaL...
Since the adsorption chillers do not use primary energy as driving source possibility to employ low temperature waste heat sources in cooling production receives nowadays much attention of industry and science community. However, performance thermally driven systems is lower than that other heating/cooling systems. Low coefficients are one main disadvantages coolers.

Abstract Energy efficiency is one of the most important topics nowadays. It strictly related to problem energy demand, policy, environmental pollution, and economic issues. Because technological development, using more advanced processes in almost every part industry increasing demands both for a high standard living simplification processes, demand growing. This can be observed, e.g., building sector—air conditioning present new people expect quality thermal conditions. At same time, many...
One of the main disadvantages conventional fixed-bed adsorption chillers is low coefficient performance due to high voidage sorbent beds. The common method, which can help handle this problem, modifying beds' design, including application fluidization. An innovative idea, shown in article, constitutes use fluidized bed sorbent, instead conventional, fixed-bed, commonly used nowadays chillers. Bed-to-wall heat transfer coefficients for fixed and beds adsorbent are determined study. Effects...
Adsorption cooling and desalination technologies have recently received more attention.Adsorption chillers, using eco-friendly refrigerants, provide promising abilities for low-grade waste heat recovery utilization, especially renewable of the near ambient temperature.However, due to low coefficient performance (COP) capacity (CC) they not been widely commercialized.Although operating in combined heating (HC) systems, adsorption chillers allow efficient conversion management sources thermal...
