Question

只考虑xxx进气，采用PDA测量手段研究xxxx旋流杯流场和喷雾场，并改变xxxxx的旋流数和进气面积，得到以下基本结论：
1)xxxxx旋流数增大时，回流的速度变化不大，流场结构的变化主要表现在回流区宽度的增大，而二级涡流器的旋流数增大时雾化效果变好。
2）xxxxx面积的减小导致xxx头部的总进气量减少, 但一级xxxxx的进气量却相对增加,有利于燃油的雾化，同时由于旋流气体强度的减弱，回流区的宽度也会变小；而当面积增大时恰好相反。

Answer 1

英文：Xxx only consider Inlet, a PDA means of measuring cup on xxxx swirl flow and spray field and change the xxxxx and the swirl of air space, by the following basic conclusions:
1) xxxxx swirl increase the number, speed the return of little change, the flow changes in the structure of the main performance area in the back of increased width, and the two swirl for the increasing number of cyclone fogging effect change better.
2) xxxxx xxx lead to the decrease of the total head into the air decreased, but a xxxxx into the air but the relative increase is conducive to the atomization of fuel, and because of the weakening Cyclone gas intensity, will return to the width Smaller, and when the area increase when quite the opposite.
日文：xxxのみを考虑入り口は、计量カップをXXXXの手段としてのPDAの流れと涡巻き模様のフィールドに変更し、 xxxxxにスプレーと涡巻き模様の空気のスペース、は、以下の基本的な结论を出す：
1 ） xxxxxに涡巻き模様の数を増やす、スピードの返还をほとんど変化は、构造の変化の流れの主な性能事项は、先头の増加幅、および2つの涡巻き模様は、低気圧フォギング増えてより良い効果を変更します。
2 ） xxx xxxxxには、合计の减少につながる头を空中に减少し、空中ではなく、 xxxxxには、しかし、相対的増加を助长するための燃料の微粒化、および低気圧のため、弱体化ガスの强さ、幅に复帰することを小さい、との表示时に向上することが全く逆です。

Answer 2

Only consider it is angry that xxx enters, adopt PDA measurement means to study xxxx swirl cup to flow in field and spraying field, change the swirl of xxxxx and count and enter the angry area, get the following basic conclusion:
1)When xxxxx swirl counts and increases, the pace of the reflux does not change much, increase which the change of a structure mainly displays in the width of reflux area flows, and the swirl of second vortex device counts the atomized result while increasing to become well.
2)The decrease of xxxxx area leads to the fact the total air inflow of xxx head to reduce, but the air inflow of first class xxxxx increases relatively, favorable to the atomization of the fuel, at the same time because the gas intensity of the swirl subsides, the width meeting of the reflux area is diminished; And it is just the opposite to accumulate while increasing face to face.

Answer 3

Only considers xxx air admission, uses the PDA measuring means to study xxxx turns on lathe floats wine cups the flow field and the atomization field, and changes xxxxx eddy number and the air admission area, obtains the following basic conclusion: when 1) xxxxx eddy number increases, the backflow speed change is not big, the flow field structure's change mainly displays in backflow sector width enlargement, but the second-level whirlpool's eddy number increases time atomizes the effect to improve. 2) xxxxx area reduces causes xxx forehead the total air input to reduce, but the first-level xxxxx air input actually relatively increases, is advantageous in the fuel oil atomization, because simultaneously eddy gas intensity's being weaken, the return flow region width will also change is small; But when the area increases time exactly opposite.
