The airflow of air curtain installed on the shearer carrys a part of dust produced by the shearer to the driver side under the entraining action. So, for further improvement on the dust-isolation effect, the authors put forward to adopt the rotating air curtain to prevent entainment dust from being carried into the driver side and enhance dust control. Through adding a short falling curtain at the...
In order to calculate the aerodynamic heating process of the missile head, the environmental temperature and pressure are obtained by the ballistic trajectory table and the flight Mach number are calculated. The method of fluid-solid coupled was used to compute the inner and outer field of the missile. The temperature of the missile surface and head was obtained. The result shows the fluid-solid coupled...
