SUS304 High Pressure Stainless Steel Corrugated Hose For Gas Supply

The flow resistance and heat transfer characteristics in inner tubes were studied.

The results show that the Nusselt number of the asymmetrical spiral twisted tube is significantly higher than

that of the elliptic twisted tube. Through the comparative analysis of the flow field, it can be seen that the

distortion of the three blades on the cross section of the asymmetric spiral tube causes the fluid flow

in the three blades to deviate, forming a strong secondary swirl and improving the heat transfer performance.

At low Reynolds number, asymmetric spiral twisted tubes show better heat transfer performance and higher drag factor.
