“…The comparison shows that the values of h w obtained for the single-slope solar still are somewhat nearer to the results of Kumar et al, 17 with a mean deviation of about 27.4% for the case of the solar cooker and 37.2% for the solar distiller. However, correlations related to rectangular plates give low values of h w compared to present results, with deviations of about 29.5%, 32.4%, and 38.8% for Equations ( 6), (5), and (3), respectively. The higher difference was obtained with Watmuff's correlation (Equation 2) with a deviation of 59%.…”

“…The wind convection heat transfer coefficient is of great importance in several research fields, such as building energy analysis, 1 research on animal and plant biology, 2,3 environmental sciences, 4 and energy systems research. [5][6][7][8] Appropriate estimation of h w is essential for solarbased systems. Since thermal behavior and productivity of solar distillers are highly affected by the upward thermal loss through glass cover.…”

Accurate evaluation of the wind convection heat transfer coefficient (hw) for solar‐based systems is essential, especially for solar desalination systems. Thermal behavior and productivity of solar stills are highly affected by the external heat loss through the glass cover. This paper describes a new experimental approach to estimate the hw on the glass cover of the conventional single‐slope solar distiller (CSS). Indoor experiments have been conducted under steady‐state conditions for a wind speed between 0 and 3 m/s. The hw has been evaluated through an energy balance performed on the distiller's glass cover. The results showed that increasing the wind speed increases the hw (from 5.64 to 31.57 W/m2 K) and enhances the distillation rate (from 5.28 to 7.61 mL/min). A new relationship for the hw was proposed for the CSS and compared with the experimental data available in the literature. The comparison shows that the obtained results are close to the data from solar systems, with a deviation ranging from 27.4% to 37%. However, a significant deviation was obtained with earlier models derived from flat plates (from 29.5% to 59%).

“…They are built to raise the polluted air high enough in order not to pollute the environment. Thus, chimneys which used in power plants and industrial factories need to be as tall as possible (Esmail et al, 2022). They have a slender structure due to their altitude.…”

Industrial structures built with different materials and methods play an important role in the sector with development of industry and increase in energy need. Many parameters are considered in the design and application phase of industrial structures to provide service for many years. The aim of this study is to examine dynamic behavior of reinforced concrete industrial chimneys depending on soil-structure interaction (SSI). For this reason, a reinforced concrete industrial chimney, which was exposed to the 1999 Kocaeli Earthquake, was chosen as a sample. The effect of soils with different properties (hard, medium and soft) on the dynamic behavior of the selected structure was investigated numerically by linear time history analysis in ANSYS finite element program. The horizontal component of the Kocaeli Earthquake (1999) was used in analyses. As a result of the studies, besides the mode shape and frequency of structure, stress, strain and displacements were also obtained. It has been observed that as the hardness of the soil environment decreases (transition from hard soil to soft soil), chimney apex displacements and stresses on the edge of the voids increase.
