Modifying Resin Viscoelasticity by Multifunction Cavitation Processing in a Magnetic Field

Abstract

The viscoelastic properties of polyamide 11 samples were modified by subjecting these specimens to multifunction cavitation within a magnetic field, using a device equipped with a 0.1 mm water jet nozzle. During these trials, a magnetic field was applied to the entire water jet stream while varying the distance between the nozzle and the specimen. The effects of various processing conditions were assessed by monitoring the removal of ink applied to sample surfaces. The results obtained using this technique with and without a magnetic field were also evaluated.

Precise Peening of Ni-Cr-Mo Steel by Energy-Intensive Multifunction Cavitation in Conjunction With Positron Irradiation

“…In the MFC process, the thermal decomposition of water vapor produces electrically charged bubbles containing ions such as O + , H + and OH + . In the case that a magnetic field is applied to these bubbles, the Lorentz force acts in the liquid flow direction, promoting collisions between the bubbles Yoshimura et al (2022a) that generate new bubbles so as to improve the material processing ability of the system. The authors also previously developed an energy-intensive MFC (EI-MFC) technology Yoshimura et al (2021a) that concentrates the ultrasonic irradiation generated in the vicinity of WJC bubbles, together with an MEI-MFC apparatus that applies a magnetic field to the EI-MFC process Yoshimura et al (2021a).…”

Cavitation Fusion by Energy-Intensive Multifunction Cavitation in a Strong Magnetic Field With Laser Light Excitation

“…However, other researchers were unable to replicate the results of this prior experimentation. Our own group has examined the feasibility of bubble nuclear fusion on an experimental and theoretical basis by superimposing Cavitation Fusion by Energy-Intensive Multifunction Cavitation in a Strong Magnetic Field with Laser Light Excitation International Journal of Engineering Science Technologies 51 magnetic field energy on a water jet Yoshimura et al (2022a), Yoshimura et al (2022b). This previous research demonstrated the generation of ultra-hightemperature, ultra-high-pressure cavitation producing the required fusion temperature of 1.0 × 10 8 K Yoshimura et al (2021a), Yoshimura et al (2018a), Yoshimura et al (2018b), Yoshimura (2020.…”
