The Exergy Optimization of a Flat-Plate Solar Collector Using AL2O3-Water, CuO-Water and TiO2-Water Nanofluids by Genetic Algorithm

In this study, the exergy efficiency of a flat plate solar collector using Al2O3, TiO2, CuO nanoparticles and pure water as base fluid is studied. Solar radiation is selected between 200 to 600 W/m2. The method to determine optimum values of optimization variables has been developed by Genetic Algorithm Toolbox in MATLAB software. Results show by increasing solar radiation the optimized exergy ...

A Computational Wear Model of the Oblique Impact of a Ball on a Flat Plate

Many wearing processes are a result of the oblique impacts. Knowing the effective impact parameters on the wear mechanism would be helpful to have the more reliable designs. The H-DD (Hertz-Di Maio Di Renzo) nonlinear model of impact followed by the time increment procedure is used to simulate the impact process of a ball on a flat plate. Restitution parameters are extracted and compared with t...

Stability Analysis for Wake Flow Behind a Flat Plate

Neutral stability limits for wake flow behind a flat plate is studied using spectral method. First, Orr-Sommerfeld equation was changed to matrix form, covering the whole domain of solution. Next, each term of matrix was expanded using Chebyshev expansion series, a series very much equivalent to the Fourier cosine series. A group of functions and conditions are applied to start and end points i...

Comparative performance assessment of flat plate and evacuated tube collectors for domestic water heating systems in Kerman, Iran

This study represents a year-round energy performance of two solar water heating (SWH) systems with a 4m2 flat plate collector (FPC) and an evacuated tube collector (ETC) operating under the same weather conditions. The energy performance of the two considered systems was compared on a monthly and yearly basis. The obtained results showed that for an annual total solar insolation of ...
