Description
本発明は、2012年11月20日に出願された米国仮特許出願第61/728,525号、2013年6月24日に出願された米国仮特許出願第61/838,675号、および2013年10月15日に出願された米国仮特許出願番号第61/891,118号から優先権を主張する。上記米国仮特許出願は、参照により本明細書に組み込まれる。
方程式L = d×m×SM
ここで、dは傾斜オリフィス直径[m]であり、mは定数であり、SMは(ν/σ)×(2ΔP×ρ)1/2で定義された無次元係数であり、νは動粘度[m2/s]であり、σは表面張力[N/m]であり、ΔPは傾斜したオリフィスの圧力降下[N/m2]であり、ρは流体の密度[kg/m3]である。
あるいは、
方程式L =(A0×ΔP)/[σ+C×d0×ΔP/ρL]、C =(ρaπCdc/3)
ここで、d0は傾斜オリフィス直径[m]であり、A0=πd0 2/4はオリフィス面積[m2]であり、ΔPは傾斜したオリフィスの圧力降下[N/m2]であり、σは表面張力[N/m]であり、ρLは流体の密度[kg/m3]であり、ρAは空気の密度[kg/m3]であり、Cdcは軸流における気筒の表皮摩擦抵抗係数である。
表1:L/d = m×SMモデルによる(L/d)の推定:m = 10.921及び(L/d)0 = 0
d0= 0.3 mm、ΔP = 1.0 bar、ボンド数B0=(ρgdj 2)/σ= 0.0122 << 1*
*は、重力の影響が無視できることを示す。
Cdc= 3×(σW-σD)(σW×σD)/[ρAπ×d0×ΔPC×(ρW-ρD)]に基づいて独立して照合または推定することができる。
表2:液体の性質:νは動粘度である。 σは表面張力である。 ρは流体の密度である。
表3:選択された液体の分裂および蒸発の比エネルギー
表4:色々な圧力での総有効比エネルギーTASE(J/gm)
表5(A):色々な衝突角θでの表面張力に打ち勝つために必要な差圧(ΔP [bars])
表5(B):色々な衝突角θでの1グラムを蒸発させるために必要な差圧(ΔP [bars])
から計算することができる。
