摘要
Purpose - This paper aims presents topology optimization of microfluidic channels with reverse flow. Design/methodology/approach - A circular chamber with an inlet and an outlet are chosen as an initial design domain. The energy dissipation is chosen as an objective function. The incompressible Navier-Stokes equation is applied for simulating the fluidic motion in channels. An artificial friction force which is proportional to the flow velocity is substituted into the Navier-Stokes equation for controlling the design variable. Findings - The effect of a bifurcation angle between the inlet and the outlet on a topological structure is analyzed. The flow velocity, pressure and design variable for every bifurcation angle are obtained. Originality/value - This work is instructive to the design of a microfluidic system.
