Ms. Ogawaguchi introduced some numerical simulations of coal flows in a conveyor chute at coal-fired power plants by using DEM, fuel pool sloshings in nuclear power plants by using MPS, and flow accelerated corrosions in carbon steel pipingpiping at power plants by using CFD. On the other hand, she also introduced the efficiency of mathematical considerations based on an example of sloshings in the fuel pool, and shown that Miles’ spine and response curves agree well with experimental results by correcting the nonlinear behavior of sloshing in the fuel pool based on the Duffing equation taking into account of nonlinear spring restoring force with one degree of freedom. Based on these cases, she explained how numerical simulations and mathematics are useful in reducing the costs required for operating and maintaining equipments in the company. She also touched on useful knowledge for faculty members promoting the industry-academia collaborations and for students considering employment such as the differences between the university and the industry.
