Ozone generation by nonequilibrium atmospheric pressure discharge plasma using packed particle bed with titanium oxide by Kazuhiro ISHIMARU

“…The presence of the dielectric layer between the discharge gap leads to the formation of a large number of micro-discharges of nanosecond duration, and a thermal nonequilibrium plasma condition in atmospheric pressure is formed by this phenomenon. In this study, the reaction field by packed particle bed with titanium oxide was formed in a traditional ozone generator. …”

Effect of annealing on fatigue behavior of partially stabilized zirconia by Akira YOSHIKAWA, Kiyohiko IKEDA, Hiizu OCHI, Osami KOBORI

“…In this study, PSZ specimens were annealed for 100 h at temperatures of 200, 400 and 600°C in a low vacuum atmosphere to improve the fatigue resistance. Both static and cyclic fatigue tests were conducted on the annealed specimens under static four-point bending and under cyclic reversed plane bending, respectively. …”

Evaluation of the effect of pressure conditions on the aggressive intensity of hydrodynamic cavitation produced by a Venturi tube by Shu HOSHINO, Hitoshi SOYAMA

“…At the upstream pressure p1 = 2.6 MPa and the downstream pressure p2 = 0.5 MPa, the aggressive intensity of hydrodynamic cavitation increased to be 36 times larger of the value corresponding to the atmospheric downstream pressure. While the optimum downstream pressure depended on the upstream pressure, the cavitation number was nearly constant for all upstream pressures. …”
