Fractal approach to concentration distribution of atmospheric fine particle sizes
نویسندگان
چکیده
With the increase of particulate pollution in atmosphere, it becomes extremely significant to understand overall distribution characteristics particulates and their adsorption toxic gases for source analysis precise controlling atmospheric matters. The fractal theory was adopted analyze particle sizes Xi?an city, China. Results showed dimension matters ranged from 4.32-4.83, with an average 4.54. A higher predicts a concentration fine particles. Additionally effects outdoor temperature, humidity, wind speed on were also studied experimentally

Fractal Approach to Large–Scale Galaxy Distribution
We present a review of the history and the present state of the fractal approach to the large-scale distribution of galaxies. The roots of the modern idea of cosmic fractality go to the beginning of the 20th century, when hierarchical world models were proposed by Fournier and Charlier. Fundamental aspects of hierarchical matter distribution was discussed by Einstein and Selety in the correspon...
متن کاملNumerical Modeling of Fine Particle Fractal Aggregates in Turbulent Flow
A method for prediction of fine particle transport in a turbulent flow is proposed, the interaction between particles and fluid is studied numerically, and fractal agglomerate of fine particles is analyzed using Taylor-expansion moment method. The paper provides a better understanding of fine particle dynamics in the evolved flows.
متن کاملFractal bird nest distribution produces scale-free colony sizes.
The spatial distribution of organisms often differs across scales. For instance, colonial bird populations could be described, from large to small scale, as scattered clumps of otherwise regularly distributed breeding pairs. We analysed the distribution of nests of a large colonial population of white storks (Ciconia ciconia) and found a fractal pattern in each of the 4 study years. Moreover, w...
متن کاملestimating soil water retention curve using the particle size distribution based on fractal approach
introduction: water and soil retention curve is one of the most important properties of porous media to obtain in a laboratory retention curve and time associated with errors. for this reason, researchers have proposed techniques that help them to more easily acquired characteristic curve. one of these methods is the use of fractal geometry. determining the relationship between particle size di...
