- Example Sentences:
| 1. | The last or main injection pulse is set around tdc . when the diesel spray impinging on the combustion wall , the bump around the combustion chamber wall can strip off the wall jet and form a secondary spray in combustion chamber , so the fuel and air can mix well and homogenous
在主喷射时刻，利用燃烧室壁面的bump迅速剥离壁面射流，在空间形成二次射流，二次射流进入燃烧室空间后，再一次与空气混合，形成相对均匀的稀混合气。 | | 2. | Jet impingement cooling is an advantage method in heat transfer enhancement owing to its extremely high local heat transfer coefficient and simple structure . as regard as the combustor flame tube cooling structure is concerned , the impingement - converse convection - film composite cooling is an effective method , in this composite cooling structure , the impingement cooling problem could be modeled as impingement inside semi - confined channel
对于冲击-逆向对流-气膜复合冷却的火焰筒结构而言,火焰筒壁面冷气侧的冲击冷却实质上是半封闭通道的冲击冷却,即冲击射流从冲击孔板喷出,冲击到换热靶面后形成壁面射流沿通道单方向流出。 | | 3. | Planar laser induced fluorescence ( plif ) was used to study the spray / wall impinging in constant volume vessel . the experimental result show that when fuel spray impinging on the plane wall , wall jet was formed while fuel impinging on a plane wall with a bump , when the wall jet meet the bump , a secondary jet can be formed . some parameters affecting the secondary spray were studied , including bump height , the secondary impinging distance , impinging distance and injector parameters
对传统燃烧室和bump燃烧室内燃油空气混合过程进行了对比研究，发现燃油撞壁以后在传统燃烧室壁面形成壁面射流，这一层燃油浓度很高，很难与空气混合，而在bump燃烧室内，壁面射流遇到bump后，会在空间形成二次射流，二次射流进一步能快速与空气充分混合。 | | 4. | It is found that , the heat transfer coefficients in the area after at stagnation point is higher than that of common jetting although the heat transfer coefficients are smaller at stagnation point , and , comparing to common jetting , rotary jetting contributes to the even distribution of heat transfer coefficients near stagnation point
结果表明，尽管旋转射流的努谢尔特数在驻点附近低于普通射流的努谢尔特数，但在壁面射流区高于普通射流的努谢尔特数。与普通射流相比，旋转射流导致驻点附近区域的换热特性趋于均匀化。 |
