Моделирование изменения распределений концентрации и переменной плотности по длине канала
Аннотация
Рассматривается прогнозирование процесса диффузии при распределении концентрации переменной плотности по длине водного канала, приводится аналитическая формула по определению длины пути полного смешения коллекторной воды с пресной водой.
Коллектор сувининг канал суви диффузияси оркали узгарувчан концентрациянинг узгаришини башоратлаш каралади. Канал узунлиги буйича коллектор суви ва канал суви аралашиш концентрациясининг аналитик формуласи берилади.
The prediction of the diffusion process is considering for the distribution of the concentration of variable density along the length of the channel. There is an analytical formula, given to determine the light of the path of complete mixing of the collector water with fresh water.The lands of Syrdarya, part of Jizzakh and other regions, have collector saline waters, for transfer and use in irrigation areas of these waters are mixed by canal water to such an extent that the concentration of mixed water is acceptable for irrigation. When transferring collector salt water to the channel, a diffusion process takes place, where the concentration and composition of the fresh water of the main channel changes.Consider the prediction of the diffusion process when the concentration of a variable density is distributed along the length of the channel.The following problem was solved: mixing a plane-parallel jet with a moving surrounding liquid. Mixing a jet flowing out of a very small orifice with a moving medium. An analytical formula for determining the concentration of a mixture of collector and wastewater is given. The formula for determining the length of the path of complete mixing of collector water with fresh water is obtained. Recommended for use in irrigation of lands of the Syrdarya and Jizzakh regions.
