چکیده

This paper describes a dust modeling technique. An empirical method is used to visually simulate the effect of dust accumulation on object surfaces. The dust amount is first predicted based on the properties of the surfaces: the surface inclination and stickiness. This predicted amount is then adjusted according to some external factors: surface exposure to wind and scraping off by other objects. The calculated dust amount is finally perturbed by a noise function on rendering to give a fuzzy visual effect. CR

Investigating the RegCM model ability in simulation ‎of summer Khorasan dust ‎

The Great Khorasan in northeast Iran has a variety of surface structures and plains and high peaks, but due to its vicinity to the deserts of Afghanistan and Turkmenistan, it is affected by dust all the time, especially in summer. The purpose of this study was to simulate summer dust in this region by RegCM model. For this purpose, during the period 2000 to 2017, three extreme dust events were ...

Dust in Ventilation Ducts: Accumulation, Measurement and Removal Report A9

This thesis focuses on dust accumulation in, and removal from, recently installed supply air ducts and on the bristle behaviour of rotating duct cleaning brushes. The results of dust accumulation, measured using three different methods, were compared and the amount of dust in newly installed air ducts was evaluated. The vacuum test was found to be an efficient method of collecting dust samples ...
