Adaptive Time Windows for Discrete Adjoint Topology Optimization of Unsteady Flows
Zongyuan Liu, Kentaro Yaji, Musaddiq Al Ali +1
Rather than prescribing an evaluation interval a priori, the proposed framework characterizes each evolving unsteady flow using a sequence of time windows. A consecutive-window con…
Maximization of Supercapacitor Storage via Topology Optimization of Electrode Structures
Jiajie Li, Xiang Ji, Shenggao Zhou +1
As widely used electrochemical storage devices, supercapacitors deliver higher power density than batteries, but suffer from significantly lower energy density. In this work, we pr…
Topology optimization for microfluidic mixers by a phase field method
Zongyuan Liu, Jiajie Li, Shengfeng Zhu
We investigate multi-physical topology optimization for microfluidic mixers employing the phase-field model. The optimization problem is formulated using a modified Ginzburg-Landau…
Shape Optimization of Supercapacitor Electrode to Maximize Charge Storage
Jiajie Li, Shenggao Zhou, Shengfeng Zhu
We build a new mathematical model of shape optimization for maximizing ionic concentration governed by the multi-physical coupling steady-state Poisson-Nernst-Planck system. Shape…
