Description
本願は、2011年9月30日出願の米国仮特許出願第61/541,953号の権利を主張するものであり、その全てが参照により本書に援用されている。権利は米国特許法119条に準じて主張されている。
一連の微小構造を利用して流体流れをプログラムする機能を調査するために、円筒を微小流体チャネルのストリームを横切る様々な位置に配置し、プログラムスキームのオペレータとして機能させた。これらの幾何学的な障害物を利用して流れに著しい変形を引き起こし、流体の塊を局所的に移動させて流体ストリームを変形させる、有用な最終回転二次流れを作り出すことができる。特に、流体慣性は多くの場合重要とは考えられないため、従前の微小流体システムでは、ピラー周囲の流体の最終的なねじれは無視されてきた。運動の線形方程式を時間反転(time-reversal)したときの流れの鏡面対称性により、慣性を有しない直線チャネル内でのピラー周囲の流れ(すなわち、ストークス流れ)は前後の対称性を要求する。したがって、チャネルの断面内に方向付けられた二次流体運動は、円筒形の中央平面を通過した後に完全に反転する。
Re=ρUH/μ
である。
