Modeling of dispersion and local concentration of pollutants in the roadside airspace

Abstract: Дослідження дорожніх умов та виявлення об'єктів підвищеного екотоксикологічного впливу з боку автотранспорту в м. Києві дало змогу за допомогою програмного комплексу MathCad створити просторові моделі та побудувати поля розсіювання емітентів відпрацьованих газів автомобілів (на прикладі чадного газу СО), а також визначити умови розповсюдження забруднювачів до і після модифікації моторного палива дизельної складової транспортного потоку розробленими багатофункціональними присадками й добавками оксигенатного біо… Show more

“…Frequencies of occurrence of SE winds (а) and WNW (b) in Atlanta, Georgia, USA [23] However, the results obtained based on this model agree well with the real ones only in cases of homogeneous, laminar flow of the medium, but lose effectiveness in the presence of obstacles and changes in weather conditions (wind direction and strength, humidity level, etc.). As stated in the article [21], such calculations give an ambiguous result, as they require consideration of various factors. The registered indicators, in turn, can also be subject to changes, especially in the surface layer of the air, because of which measurements must be carried out often and with the necessary accuracy.…”
