In this study, the energetic and exergetic analysis of a multi-effect desalination system with a thermal vapor compression desalination system has been numerically evaluated. For this purpose, the mass, energy, and exergy balance equations for the thermo-compressor, first effect as well as middle effects, and condenser have been developed. The effects of motive steam pressure and number of effects on yield, gained output ratio (GOR), performance ratio (PR) and irreversibility have been examined. Nanoparticles were used to improve the heat transfer properties at different stages. The highest rate of exergy destruction with 61.67% is concerned with thermo-compressor, owing to the large difference between the motive steam pressure and the entrained steam. The lowest exergy losses rate among the various components was 4.89% for the condenser, due to the fact that much of the final distillate steam entrained the thermo-compressor. As the number of effects increased from 1 to 7, the yield, GOR as well as PR, improved by approximately 590% and the irreversibility reduced by 1.88%. As the motive steam pressure increased from 400 to 1290 kPa, the yield decreased by 25.45% while the GOR and PR improved by 12.62 and 14.8%, respectively. From the second law viewpoint, irreversibility intensified by 16.11% which in turn diminished the second efficiency by 3.17%. © 2021, Akadémiai Kiadó, Budapest, Hungary.

The LL-37 peptide is an antimicrobial agent derived from human cathelicidin. In addition to their antimicrobial properties, these peptides can activate the immune system through various mechanisms and contribute to autoimmune diseases. In the current study, we describe the atomic behavior of this protein in an aqueous environment inside of metallic nanochannel (Fe nanochannel). For this purpose, Molecular Dynamics (MD) approach was implemented in equilibrium conditions. A Large Scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) is used in this computational study. Computationally, the various atoms interaction described by Universal Force Field (UFF), TIP4P, and Embedded Atom Model (EAM). Furthermore, physical factors like potential energy, temperature, Radial Distribution Function (RDF), density/velocity/temperature profiles, and protein volume were calculated for atomic behavior description of the LL-37 protein-water system. MD outputs indicated the atomic stability of protein structure in an aqueous environment inside metallic nanochannels. Numerically, the LL-37 protein volume changes from 3906.81 Å3 to 3900.11 Å3 value after t = 10 ns. Also, the maximum density and velocity/temperature profiles reach 0.0225 atoms/Å3 and 0.0124 Å/fs/435.22 K (respectively), values detected in the initial/final and middle bins MD box.
