Description

Ushbu maqolada atmosferada gazli aralashmalari va zararli kichik o'lchamli aerozollarning ko'chishi va diffuziyasi jarayonining matematik modeli qarab chiqilgan. Ishlab chiqilgan matematik model gaz aralashmalari va zararli moddalarni chiqarish manbalarining ish rejimlarini, shuningdek, ularning o'rganilayotgan jarayonga ta'sirini hisobga oladi. Boshqa mualliflarning ishlaridan farqli o'laroq, zarrachalarning cho'kish tezligi vaqtning har bir qatlamida va har bir fazoviy o'zgaruvchi uchun alohida ko'rib chiqilgan. Masalani yechish uchun vaqt va fazoviy o'zgaruvchilar bo'yicha yuqori tartibli approksimatsiyaga ega oshkormas ko'rinishdagi chekli ayirmali sxemadan foydalanib, sonli algoritm ishlab chiqilgan. Ishlab chiqilgan matematik apparat asosida hisoblash tajribalarini o'tkazishning dasturiy vositasi joriy etildi. Sonli hisoblashlar shuni ko'rsatdiki, atmosferada gazsimon birikmalar va mayda aerozol zarralarining tarqalishida meteorologik parametrlar asosiy rol o'ynaydi. O'rganilayotgan jarayonga o'simlik qoplami, relyef va ifloslantiruvchi moddaning xususiyatlari sezilarli ta'sir ko'rsatadi. Tahlillar shuni ko'rsatadiki, yozda ifloslantiruvchi zarrachalar kamroq hajmda yutiladi, namgarchilik yuqori bo'lgan mavsumlarda esa ifloslantiruvchi zarrachalarning yutilishi yuqori bo'ladi
