Anode influence on the electroplating system was investigated when natural convection heat transfer in a packed bed is simulated by mass transfer based on the analogy. The cathode to anode area ratio (A_c/A_a) was varied from 1 to 50. For three different anode positions of top and bottom of test section and corner of acryl tank, the distance of anode to cathode bed was varied: 0.01, 0.03, 0.07 m in all heating spheres experiments. The sphere diameter was 0.006 m, which corresponds to Ra_d of 1.83×10⁷. The duct diameter was 0.06 m and bed height was 0.025 m. The Sc corresponding to the Pr was 2014. The verification test result for a single heating sphere in unheated packed bed agreed well with the extrapolated correlation of Achenbach (1995). The anode influence experiments for all heating spheres showed that the limitation of the area ratio is about 20. The desirable positions of anode are the bottom of test section and corner of the acryl tank, regardless of the distance between the anode and cathode packed bed.

在此基础上，通过传质模拟填充床中自然对流传热，研究了阳极对电镀系统的影响。阴极与阳极的面积比（A _c / A _a）为1到50。对于测试部分的顶部和底部以及丙烯酸罐的角落三个不同的阳极位置，阳极到阴极床的距离变化为0.01，在所有加热球实验中分别为0.03、0.07 m。球直径为0.006m，对应于Ra _d为1.83×10 ⁷。管道直径为0.06 m，床高为0.025 m。对应于Pr的Sc是2014年。未经加热的填充床中单个加热球的验证测试结果与Achenbach（1995）的外推相关性非常吻合。阳极对所有加热球的影响实验表明，面积比的限制约为20。无论阳极与阴极填充床之间的距离如何，阳极的理想位置是测试区的底部和丙烯酸槽的角落。
