initial turbulenceとは 意味・読み方・使い方

At least in an initial stage of a compression stroke, the air and combusted gas in the cylinder constitute a state having a concentration distribution, and a strong turbulence is generated in the cylinder inside near the compression top dead center so that the agitation of the gas is accelerated to reduce the concentration distribution between the air and combusted gas in the cylinder.例文帳に追加

少なくとも圧縮行程の初期においてシリンダ内の空気と既燃ガスが濃度の分布を有する状態を構成するともに、圧縮上死点近傍で該シリンダ内に強い乱れを生じさせることで気体の攪拌を促進し、該シリンダ内の空気と既燃ガスの濃度分布を低減する。 - 特許庁

A flow field inside a room having specific size and shape is previously obtained in the fluid numerical analysis by a turbulence model using uneven meshes or the like, and the inside of a 1 m BOX in the neighborhood of an ion generation device is newly divided into even meshes, is replaced with an air velocity in the even meshes, and is stored as an initial condition.例文帳に追加

予め、特定の大きさ及び形状の室内での流れ場を不均等メッシュを用いた乱流モデルにより流体数値解析にて求めておき、イオン発生装置の周囲１ｍＢＯＸ内を均等メッシュに分割しなおして当該均等メッシュにおける風速に置き換えて初期条件として記憶しておく。 - 特許庁
