G606 2次元平行平板間内の磁場勾配環境下での磁性サスペンションの流れに関する格子ボルツマン・シミュレーション(GS6-2 数値計算,一般セッション)

抄録

We have investigated various problems that arise in applying the Brownian dynamics method to a suspension composed of rod-like hematite particles, which have a magnetic moment normal to the particle axis direction. The accuracy and the deviation of simulation results from theoretical solutions have been discussed by comparing with the theoretical results that were obtained by solving the basic equations of the orientational distribution function. The present simulation results can well qualitatively reproduce the characteristics of the negative magneto-rheological effect that was predicted by the previous theoretical investigation.
