dc.description.abstract | Розглянуто задачу адвекцiї–дифузiї в неоднорiдному середовищi з тонким каналом. До розв’язування цiєї задачi застовано рiзномасштабний метод скiнченних елементiв. Показано, що отриманий розв’язок є стiйким та збiжним для достатньо великих чисел Пекле. Наведено та проаналiзовано результати обчислювальних експериментiв. | |
dc.description.abstract | The advection-diffusion in an inhomogeneous medium with a thin channel is considered. The multiscale finite element method is applied to solving the formulated model problem. It is shown that the obtained solution is stable and convergent for sufficiently large Peclet numbers. Numerical examples are presented and analysed. | |
