For the purpose of simulation of the deployment and retrieval of deep sea mining system, two methods for assessing the added mass of components of deep sea mining system are mainly proposed in this work. The first method is referred to as the Hess-Smith method which is based on surface panel method and potential theory, the surface of the moving object is discretized to lots of panels to approximate...
According to characteristics of fully mechanized top-coal caving face and related survey date, a mathematical model of dust movement was derived from gas-solid two-phase flow theory. Numerical simulation of the dust concentration was made with CFD software FLUENT. The result matches well with the related survey date and shows that most of the dust move with the wind and little disperses at random...
