Recent developments in climate change have increased the frequency of dust storms in the Middle East. Dust storms significantly influence the performances of solar energy harvesting systems, particularly (photovoltaic) PV systems. The characteristics of the dust and the mud formed from this dust are examined using various analytical tools, including(More)
Owing to recent climate changes, dust storms are increasingly common, particularly in the Middle East region. Dust accumulation and subsequent mud formation on solid surfaces in humid environments typically have adverse effects on surface properties such as optical transmittance, surface texture, and microhardness. This is usually because the mud, which(More)
—In this work, we modeled a system of two fluids of different densities contained in an open boundary. A jet injection of a lighter fluid is introduced at suitable location to the system. The injection velocity of the jet influenced the surface of the fluid contained in the system. This heavier fluid surface deformation is investigated in terms of relation(More)
The present study examines the mechanical properties of kidney stones subjected to laser irradiation. Thermal and stress analysis due to laser irradiation was carried out theoretically while the accuracy of the theoretical results was checked by the experiment. In the experiment a Nd-YAG laser was used to irradiate the target. The experiment was performed(More)
