XULOSA Makro- va mikrog’ovakli silindrik zonalardan tuzilgan, fraktal strukturali muhitlarda modda ko’chishi masalasi qo’yilgan va sonli yechilgan. Modda ko’chish tenglamasida konvektiv haddagi hosila tartibi ni ikkidan kamayishi makrog’ovakda konsentrasiya maydoninig kengroq tarqalishiga olib kelishi ko’rsatilgan. Bunday makrog’ovakdagi «tez diffuziyalanish» mikrog’ovakda ham «tez diffuziyalanishga» olib keladi. Modda ko’chish tenglamasida diffuziya hadidagi hosila tartibining kamayishi mikrog’ovakda «tez diffuziyalanishga» va profillarining kamroq yoyilishiga olib kelgan. G'ovak muhitda oqimdagi moddalarning harakatini modellashtirish suv, tuproq yoki havoning yomonlashishini bashorat qilish, konchilik, biologiya, kimyo va boshqalar kabi turli sohalarda juda muhimdir. Modda ko`chishi jarayoni konvektiv-diffuziya tenglamasi bilan ifodalanadi. Uchinchi bobda tenglama oshkor chekli ayirmalar usuli yordamida yechilgan hamda fraktal g'ovak muhitda moddalarning bo'ylama va ko'ndalang yo'nalishda ko`chishi jarayonlari modellashtirilgan va bir va ikki o’lchovli fraktal konvektiv-diffuziya tenglamasi bilan ifodalangan. Natijalar hosila tartiblarning turli qiymatlari yordamida olingan. Olingan grafik va elektron jadvallardan shunday xulosa qilish mumkinki, hosilalarning tartibini kamaytirish konsentratsiya profillarining kengroq yoyilishiga olib keladi.
