lateral diffusion of a free air jet in slot-die melt

Transactions of the JSME (in Japanese)

The jet breakup behavior is observed with a high speed video camera the front position of the jet and the jet breakup length are estimated with the visual observation results In the high injection velocity conditions it is found that the jet breakup is dominated by fragmentation induced by the surface instability due to the relative velocity even in the surface solidification condition In

Additive Manufacturing: Unlocking the Evolution of Energy

For example Dede et al used topology optimization with respect to heat transfer and pumping power to design a heat sink for confined jet impingement air cooling (Figure 2g) which was subsequently fabricated out of AlSi12 using AM as depicted in Figure 2h) 47 Experimental results showed this novel AM realized heat sink design results in coefficient of performance (COP) being 44% higher

Numerical analysis of new modified melt

Consequently the interaction of the jet and the surrounding air can cause the kinetic energy loss of the jets Based on the above analysis we do some improvements based on the blunt die and redesign the geometry of the melt‐blowing dies that to a great extent eliminate the backflow zone and inhibit the lateral diffusion of the jets Our
