The characteristic of fluid dynamics is one of the key factors, which affect coating quality. In the paper, the present work examines the fluid dynamics in the flow field of a two - wire - arc spray gun. The asymmetric character and turbulent behaviors are obtained with numerical computation and simulation based on Fluent.

The characteristic of fluid dynamics is one of the key factors, which affect coating quality. In the paper, the present work examines the fluid dynamics in the flow field of a two - wire - arc spray gun. The asymmetric character and turbulent behaviors are obtained with numerical computation and simulation based on Fluent. Moreover, velocity distribution is found that the mental droplets velocity declined gradually after acceleration near the exit of the jet nozzle, especially the droplets on the edge of the fluid lost their kinetic energy drastically and dissipate into ambient environment, which produces waste and pollutants. In order to increase the deposition ratio and coating quality, spray distance should be paid cautious attention.

电弧喷枪流场特性是影响电弧喷涂质量的关键因素之一。运用商用流体计算软件Fluent,对手持式高速电弧喷枪头部及枪外射流进行了模拟计算,通过分析可以看出,雾化射流具有不对称、湍流等特点,其射流速度分布有明显的先递增后衰减的规律,在流场推动下,雾化的金属粒子首先被流场加速,到达最大值后速度开始衰减,随着喷涂距离的增加,粒子的速度逐渐下降,特别是靠近流场外部的粒子,速度的下降更快,最终失去了与基底的结合动能,成为灰尘,飞散到环境之中,这既浪费了材料,又污染了环境。为了提高沉积率,保证涂层质量,喷涂距离的控制显得非常重要。

The fluid dynamics in the jet field of a high velocity wire arc spray gun is one of the key factors to coating qualities. With the application of Fluent, the jet flow dynamics of a spray gun is simulated and computed, which concludes that the jet field could be characterized by three regions: the core region, the entrainment region, and the fully turbulent region. Influenced by the intersecting and reflecting of shock waves, the velocity distribution of the jet is non-homogeneous and asymmetric, and the axis velocity is severely fluctuated. Moreover, The flow in the wire plane is more divergent than that in the wires’ vertical plane. Therefore, it’s an important way to improve spray quality with appropriate spray distance and a special designed cap.

电弧喷枪流场特性是影响电弧喷涂质量的关键因素之一。文中运用 CFD 软件 Fluent,对高速电弧喷枪头部及枪外射流进行了模拟计算,通过分析可以看出,枪外射流可以分为射流核心区、射流卷吸区和射流湍流区。受欠膨胀激波反射和相交的影响,枪外射流的速度分布具有不均匀性,其轴线射流速度存在剧烈波动,同时呈现先递增后衰减的规律。受丝材的影响,枪外射流速度分布呈现空间不对称性,其丝材所在平面流场的发散性大于丝材垂直平面的发散性。为了保证涂层质量,提高沉积率,喷涂距离控制以及喷嘴封闭气帽形状的合理设计显得非常重要。

With the application of Fluent, the jet flow field of a wire-arc spraying gun was simulated and computed, which could be characterized by four regions: plasma region, core region, entrainment region and the fully turbulent region. The results showed that the plasma region had very limited effect on the other regions. It only caused 20~40 degree rising of the temperature on the axis of jet flow. But in the plasma region itself, the velocity and temperature were severely fluctuated, up to 1 600 m/s and 6 800 K...

The results showed that the plasma region had very limited effect on the other regions. It only caused 20~40 degree rising of the temperature on the axis of jet flow. But in the plasma region itself, the velocity and temperature were severely fluctuated, up to 1 600 m/s and 6 800 K respectively. From anode to cathode, the average temperature was gradually reduced from 4250 K to 538 K.

运用CFD软件,对高速电弧喷枪的流场进行了模拟。通过分析计算结果,将射流分为电弧区、核心区、卷吸区和湍流区4个部分。电弧区内部速度和温度起伏剧烈,但对其外3个区域的流场速度分布影响不大,对轴线温度影响为20~40K。电弧区内部最高温度为6800K,分布在阴极表面上,阴极的平均温度为4250K,从阴极到阳极,电流密度和电弧温度都逐渐降低,阳极的平均温度为538K。
