The volume of fluid (VOF) method was used to track the free surface of sloshing. External excitation was imposed through the motion of the tank by using the dynamic mesh technique. The study shows that if the tank is subjected to multiple coupled excitations and resonant excitation frequencies, liquid sloshing will become violent and sloshing loads, including impact on the top wall, will be intensified.展开更多
The effect of repetitive pulsed microwaves (10 GHz, pulse duration of 100-300 ns, pulse repetition rate of 4-25 pulse per second, peak power density of 0.04-3.5 kW/cm^2) on mastocytoma P815, Ehrlich carcinoma, norma...The effect of repetitive pulsed microwaves (10 GHz, pulse duration of 100-300 ns, pulse repetition rate of 4-25 pulse per second, peak power density of 0.04-3.5 kW/cm^2) on mastocytoma P815, Ehrlich carcinoma, normal spleen cells and wound healing was investigated. It was found that short-time irradiation with an intensity of 0.9-1.5 kW/cm^2 inhibited proliferation of tumor cells in vitro, whereas at same time it contributes to proliferation of normal spleen cells in vitro. The repetitive pulsed microwaves with an intensity of 0.04-1.5 kW/cm^2 stimulated healing of skin wounds and ulcerations in mice. The effects showed a dependence on the pulse repetition rate and irradiation intensity.展开更多
