integrated energy systems utilizing renewable sources are sustainable and environmentally substitutes for conventional fossil-fired energy systems. a new multigeneration plant with two inputs, such as biomass and solar energy, and four useful outputs, such as cooling, heating, power, and distilled water, is presented and investigated in this paper. the proposed system includes evacuated tube so...

Wetcompression of a fuel aerosol has beenproposed as ameans of creating gas-phasemixtures of involatile diesel-representative fuels andoxidizer + diluent gases for rapid compressionmachine (RCM)experiments. The use of high concentration aerosols (e.g., 0.1 mLfuel/Lgas, 1 10 droplets/Lgas for stoichiometric fuel loading at ambient conditions) can result in droplet–droplet interactions which lead...

Water vapour plays in important role in the energy budget of the atmosphere. Despite many years of study there are still considerable uncertainties both in the measurement of water vapour and it’s representation in radiation models. In an attempt to reduce these uncertainties two field experiments in differing atmospheres were conducted in 1999. The results from a tropical atmosphere and a sub-...

This paper analyzes the evaporation of WIMPS (weakly interacting massive particles) from the sun, both analytically and numerically. First an analytic approximation is made by defining an appropriate truncation of a Maxwell-Boltzmann distribution for the WIMPS and calculating the exact evaporation rate from this distribution due interaction with a truly thermal distribution of nuclei. Then, the...

A mesoscopic lattice Boltzmann model is implemented for modelling isothermal two-component evaporation in porous media. The based on the pseudopotential multiphase with two components to mimic phase-change component (e.g. water and its vapour) non-condensible dry air), cascaded collision operator used enhance numerical performance. first analysed Chapman–Enskog expansion then validated by theor...

The cohesion-tension theory expounds the crude sap ascent thanks to the negative pressure generated by evaporation of water from leaves. Nevertheless, trees pose multiple challenges and seem to live in unphysical conditions: the negative pressure increases cavitation; it is possible to obtain a water equilibrium between connected parts where one is at a positive pressure and the other one is at...

In an attempt to improve the performance of hybrid absorption and mechanical vapor compression refrigeration systems and to determine the fundamental reasons for such improvements, two configurations of the hybrid refrigeration cycle with a booster compressor at different positions of the cycle (between the evaporation and the absorber, or between the generator and the condenser) are simulated ...

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...
