Higher order femtoscopy measured to examine the heat exchanger characterization of the fluid debris produced in the collisions and investigated a remarkable suppression in the bosons interferences measurement. The analogous suppression can be analyzed to explore the coherence of boson thermal particle production sources at unprecedented energies. We illustrate the particles emissions from radiated sources with statistical coherence which induce the thermal particles interferences to probe the peculiarity of the heated sources as well as the distinctions about the heat exchangers in the collisions at higher temperature. We perspicacious that the bosons seem to the pertinent aspirant of heat exchanger, and the normalized three particles correlators evaluate the existence of such hybrid phases significantly. The key point of this research is that we analyze the three particles correlations with their normalized correlations by difference equations to determine the characteristics of heat exchanger and its applications. With such distinctive and efficient approach, we observe a significant difference in the correlation functions at higher temperature and momenta regimes.

Metallic fibres in polymeric matrix are used for mouldings blocks of hybrid injection moulds improving the mechanical and thermal properties. This paper reports on the characterization of epoxy resin/short steel fibres (SSF) composites. The effect of the concentration of 2,4,6-tris (dimethylamino-methyl) phenol as accelerator in the epoxy system was evaluated by viscosity and dynamical mechanical analyses. The composites were characterized by compression and microhardness tests. The fibres dispersion into the epoxy matrix was analysed by optical microscopy. It was found that the best accelerator concentration for this type of composite was 5,0 parts by weight

The continues deficiency of consumable water is a significant issue in developing countries, and contaminated water can result in various diseases, which are often lethal. Solar desalination seems to be a promising method and alternative way for supplying fresh water. <strong>Aim:</strong> The aim of this research is to study heat transfer in desalination system and the quality of feed water, distilled water and brine compared to the quality standard. Feed water consists of salinity 12‰ and 38‰ salinity. <strong>Methodology and Result:</strong> At first, initial characterization of feed water was conducted, then temperature on fourteen points was measured using thermocouples and thermometer so heat transfer rate can be calculated. After that, the final characterization of water production was conducted. From the  observation, it was found that evaporative heat transfer for vacuum pressure of -0.05, -0.1, -0.15, -0.2, -0.25, and -0.3 bar respectively were 173.77, 180.07, 190.79, 481.66, 242.57, and 246.24 W/m2. The result of water quality test of distilled water produced from saline water desalination for some parameters respectively were pH 7.4; turbidity 2.73 NTU; TDS 27.45 mg/L; chloride 84.98 mg/L; Fe 2.13 mg/L; total hardness 0.1698 mg/L; and <em>Escherichia coli</em> 12 cell/mL . <strong>Conclusion, significance and impact study:</strong> It can be concluded that distilled water produced by desalination system was met drinking water quality standard according to Minister of Health Regulation No. 492 of 2010.

A new polymer polyferrocarbosilane (PFCS) was synthesized using polydimethylsilane and ferrocene as the raw materials. The polymer was then melt-spun into continuous PFCS fibers, cured in air and heat-treated in a nitrogen atmosphere up to 1300􀀁, a kind of Fe-containing SiC fibers were finally obtained. The SiC(Fe) ceramic fibers were combined with epoxy resin and a structural material was prepared showing excellent radar absorbing properties. HRTEM, XRD and XPS were used to characterize the SiC(Fe) fibers. The results show that the fibers are composed of β-SiC, amorphous SiCxO4-x, free carbon and small amount of Fe3Si-like microcrystals. A carbon-enriched layer of about 120nm was formed on the surface of the fibers.

This research work deals with investigation of the thermal characteristics of the Darcy–Forchheimer hydromagnetic hybrid nanofluid (Al2O3-Cu/H2O) flow through a permeable stretching cylinder. The model equations, which consist of continuity, momentum, and energy equations, are converted to a set of coupled ordinary differential equations through similarity variables transformations and appropriate boundary conditions. Brownian motion and Thermophoresis effects are mainly focused in this work. The impacts of some interesting parameters over velocity, temperature, and concentrations profiles are graphically studied. The present study will be helpful in understanding the thermal characteristics of heat transfer liquids.
