The experiment on gas jet flame extinguishing with water mist in open space was conducted in this paper. On the basis of experimental result, the process of the flame extinguishment can be classified into two categories:1) when fuel flow rate is small, the gas jet flame can be suppressed and extinguished quickly; 2) When fuel flow is large, the flame lifts from the attached position at the burner exit after suppressed by the water mist. FLUENT is used to simulate the interaction of water mist with gas jet flame. The Eddy-dissipation model (EDM) is used for combustion of flame. the water mist is simulated by Discrete Phase Model (DPM).The simulated results agree well with the experimental results. To some extent, EDM is suitable for simulating the interaction of water mist with a turbulent gas jet flame.

This paper introduces a novel radiant heat flux measurement method based on bimaterial microcantilever. Focus on flame radiant heat flux measurement, the theoretical analysis and optimization of the bimaterial microcantilever, such as its shape, size and thickness ratio are carried out. So the dynamic response time and measurement range of flame radiant heat flux are discussed and determined.

After a series of impactful predigestion,the paper established one elbow joint dynamic model in the sgittal plane when the humerus was not fixed. According to the results of the example, two conclusions were drawed: firstly, the joint reaction engendered when the humerus movable were far less than the situation of fixing;secondly, we suggested ,when upright position bend elbow strength training was making , desirable buckling shoulder angle position is at 100~200 .

A numerical study on the interaction of water mist with a fire plume was conducted using FLUENT software. The effects of different mist characteristics, such as droplet size and spray intensity, was considered in this simulation. The fire plume temperature history and velocity field were investigated. The results show that with a certain droplet size of water mist, the extinguishing time will be shorter when the mass flow of water increases, but this effect is no longer distinct after the mass flow of water mist increased to a critical value.
