Ауаның ластануы, RANS, математикалық модель, шөптiк кедергiлер, концентрация, температураАннотация
Бұл жұмыста ауа температурасының әртүрлi мәндерiнде жолдың идеализацияланған қалалық каньондарындағы ауаның ластану процесi сандық зерттелген. Бұл мәселенi шешу үшiн Рейнольдс орташа Навье-Стокс теңдеулерi (RANS) қолданылды. Бұл теңдеулер жүйесiн жабу әртүрлi турбуленттi модельдердi қолдануды қажет еттi. Математикалық модель мен сандық алгоритмдi тексеру тест тапсырмасы жүргiзiлдi. Әр түрлi турбуленттi модельдердi қолдану арқылы алынған нәтижелер эксперименттiк мәлiметтермен және басқа авторлардың есептеулерiмен салыстырылды. Бұл жұмыста қарастырылған негiзгi мiндет келесiдей сипатталады: әр түрлi температура мәндерiнде әр түрлi шөп кедергiлерiн (үздiксiз және үзiлiссiз) қолдана отырып, ғимараттар арасындағы ластаушы заттардың шығарындыларын бағалау. Зерттеу нәтижелерi жолдар бойында кедергiлердiң болуы ауадағы зиянды заттардың концентрациясын едәуiр төмендететiнiн көрсеттi. Жалпы биiктiгi 10 см болатын кедергiлердi қолдану Қорғаныс кедергiлерiнiң толық болмау жағдайымен салыстырғанда шоғырлану деңгейiнiң X = 5см қимасына дейiн 1,5 есе төмендеуiне әкеледi. Сонымен қатар, температура жағдайлары (бұл жағдайда TH = 305K) концентрация мәнiн 2 есе азайтады. Тосқауылдың көмегiмен жол жиегiндегi температураның жоғарылауы қатерлi заттардың таралуын және тұндырылуын азайтады.
