A pressure difference between intake and exhaust boundaries of the air valves is 1kPa. Flows are driven with the pressure difference. Heights of the exhaust boundaries effect on velocity fields, vortex structures and flow rates of the valves. The best performance among the valves is showed as the height of the exhaust boundary is 14mm.}, pages = {267--272}, title = {ANSYS/FLOTRANによる空気弁排気性能の数値シミュレーション}, volume = {33}, year = {2004}, yomi = {マツフジ, ヒロユキ and ヒラノ, キミタカ and キクチ, マサノリ} }
