Abstract At the city gate gas pressure reduction stations (CGSs), to prevent natural from forming a hydrate in throttle valve, is heated by heater before reaching relief valve. Heat exchangers are an essential component of industrial processes that contribute significantly total system energy. Since element impacting heat exchanger performance fouling process, all and models were dynamically simulated this study. Through coding C++ language simultaneous use fluent functions, or, other words,...
The most common type of heat exchanger used in a variety industrial applications is the shell-and-tube (STHE). In this work, impact graphene nanoplate (GNP)/water nanofluids at 0.01 wt.%, 0.03 and 0.06 wt.% on thermal efficiency, performance factor, pressure drop, overall transfer, convective transfer coefficient (CVHTC), characteristics was examined. For these experiments, new STHE designed built. novelty study use GNPs/water for first time fully experimental investigation attributes...
The study investigated the effect of adding covalently functionalized-hydroxylated multi-walled carbon nanotubes (MWCNTs-OH) and non-covalently-functionalized MWCNTs on breakdown voltage thermal properties transformer oil in a rectangular chamber. novelty present is use functionalized hydroxylated non-covalently oil, reason for selection these nanoparticles high intrinsic conductivity compared to other nanoparticles. Between both studied nanofluids, electrical performance MWCNTs-OH was...
This research aims of compare the impact mass fraction multi-walled carbon nanotubes (MWCNTs) and titanium dioxide (TiO2) nano additive on tribological thermophysical attributes turbine meter oil. These include average friction coefficient, pressure drop, wear, flash point, pour relative viscosity, kinematics viscosity index. The drops coefficient inside copper tube were simulated compared with experimental results. In this study, for synthesis lubricants from oil as a pure fluid MWCNTs TiO2...
Energy storage systems are critical as the world strives to reduce its reliance on fossil fuel energy for environmental and economic reasons. Because of their large latent heat capacity, phase change materials (PCM) well characterized candidates in this respect. Material selection, operational conditions, geometrical configurations all important elements consider when designing an system. The simulation study's major purpose is assess solidification, melting time, transfer processes...
The study was performed on the impact of adding hydrophobic TiO2 doped multi-walled carbon nanotubes (MWCNTs) heat transfer performance, breakdown voltage (BDV), and thermophysical properties (thermal conductivity coefficient, volumetric specific heat, resistivity, diffusivity, viscosity, viscosity index (VI)) transformer oil (TO). novelty this is use MWCNTs nanoparticles synthesized in TO a comprehensive experimental investigation nanofluids. Experiments were conducted systems with four...
The heat transfer coefficient and, as a result, the Nusselt (Nu) number for nanofluids are affected by parameters such thermal conductivity, capacity of fluid and nanoparticles, flow pattern, nanofluid viscosity, volume fraction suspended particles, particle shape, size. Since affecting more than two or three parameters, optimization requires calculating value function at different points, on other hand, there no suitable equations relationship between these so this purpose, existing...
Boiling is an essential process for many industrial applications, such as refrigeration, distillation, and chemical processes. The effectiveness of the heat transfer processes determines efficiencies these applications. This study presents experimental data analysis pool boiling performance 0.10, 0.15, 0.20 wt.% multiwall carbon nanotubes/water nanofluid on smooth straight, square, circular grooved surfaces. According to results, configuration S4 with a 30 mm deep groove inclined at 45°...
Combined natural and forced convective heat transfer arise in many transport processes engineering devices nature, which is frequently encountered industrial technical processes, including electronic cooled by fans, exchangers placed a low-ve-locity environment, solar receivers exposed to winds.
