Numerical simulation of heating efficiency comparison of CW laser and repeated frequency laser irradiating rotational shells

In order to use the laser energy efficiently, a numerical model is presented to simulate the temperature distribution on the rotational cylindrical shell under CW and repetition frequency laser irradiation . By numerical analyzing, a conclusion is drown that the heating efficiency of laser is affected by repetition frequency and the duty ratio of pulsed laser, and the heating efficiency of pulsed laser is greater than that of CW laser. Temperature rises with the duty ratio decreasing under the same repetition frequency of pulsed laser, while the temperature periodic change is more obvious with the lower repetition frequency under the same duty ratio of pulsed laser. When the duty ratio of pulsed laser is small, repetition frequency has little effect on the heating efficiency of pulsed las
