The weak thermal conductance of a phase change material (PCM) can be intensified by dispersing nanostructured materials called nano-PCM. Accurate conductivity (TC) prediction nano-PCM is essential to evaluate heat transport during processes, namely, melting and solidification. present study develops an artificial neural network (ANN) forecast the TC n-octadecane as PCM with dispersed oxide nanoparticles. A total 122 experimental datasets from existing literature wide range temperatures...
In this paper, an exergetic performance analysis of unglazed transpired collectors (UTC), as well optimization a typical UTC is performed. A steady-state model used to calculate heat transfers and pressure drop through perforated plate back wall. order maximize the exergy efficiency, procedure carried out for some important parameters including hole diameter pitch. The maximum efficieny 5.42% obtained. spite all thermal advantages, acts less effective in performance. Other such incident...
There are many wind synoptic stations installed all over Iran. One of these in the coasts Persian Gulf is Bardekhun station Bushehr province. The goal this study to assess energy potential region and design a proper horizontal axis turbine for site. one-year measured hourly time-series speed data extracted from measurements at height 10m, 30m 40m above ground level. Weibull distribution gives mean 4.50 m/s, 5.36 m/s 5.83 power density per year 125 W/m, 196 W/m 253 respectively heights....
In the present paper, an experimental assessment was performed on transient thermal performance of a heat sink filled by phase change material (PCM) and PCM embedded with carbon nanofibers (CNFs) titania (TiO2) nanoparticles as nanostructured materials. order to enhance conductivity PCM, CNFs TiO2 at different loadings (0.5wt. % 2 wt.% 4 TiO2) were dispersed two-step method in molten PCM. The viscosity measurements showed enhancement composite well increment viscosity. PCM/CNF PCM/TiO2...
Neural networks are powerful tools for evaluating the thermophysical characteristics of nanofluids to reduce cost and time experiments. Dynamic viscosity is an important property in that usually needs be accurately computed heat transfer nanofluid flow problems. In this paper, rheological properties phase change material containing mesoporous silica nanoparticles predicted by artificial neural (ANNs) method based on experimental database reported literature. Experimental inputs include...
This paper evaluates the performance of a concentrating photo-voltaic thermal (CPVT) hybrid system for space heating, providing hot water, and grid-connected (GC) electricity generation in city Isfahan, Iran. The GC-CPVT is ground-mounted 5.63 kWp rated power oriented north-south direction to achieve maximum output. annual monthly modeling performed by Polysun® simulation software. specifications are described heating electrical energy demand building determined. then conducted based on...
