sprue diameter

The maximum bubble volume,the maximum absorption height,bubble frequency and Sherwood number during the absorption process with orifice diameter at 5mm and 6mm were measured,and the experimental correction formulations about the maximum volume,the maximum height and the Sherwood numbers were obtained.

结果表明,喷嘴口径的增大,使最大气泡体积和最大吸收高度增大,而发泡频率、单个气泡的舍伍德数减小。

The relationship between voltage and current,current density and current efficiency,nozzle caliber and effect of anode nozzle caliber on metal distribution were investigated.

利用自行设计的实验装置,研究了瓦特镍射流电沉积不同阳极喷嘴口径下电压与电流、电流密度、电流效率关系,以及阳极喷嘴口径对沉积层的金属分布的影响。
