By using the computational fluid dynamics code, FLUENT, Numerically simulation is investigated for Youngshou power plant. Under the constant ambient temperature, the effects of different wind speed and wind direction on the thermal flow field are qualitatively considered. It was found that when considering about the existing and normally operating power plants, the thermal flow field is more sensitive to wind direction and wind speed. Based on the above results, three improved measures such as: increasing the wind-wall height and accelerating the rotational speed of the fans near the edge of the ACC platform and lengthen or widen the platform are developed to effectively improving the thermal flow field, and enhanced the heat dispersal of ACC.

Wave Slamming

In order to study the characteristics of flow field in the process of wave impact, two-dimensional regular wave numerical models were established based on the software FLUENT. RANS equations were adopted. The standard equations were used to close the Reynolds equations. VOF method was used to reconstruct the free surface. After three typical cases of wave slamming on open-piled structures were reproduced, the models were verified by experimental data and the flow field surrounding the structure was displayed visually. Then the processes of wave impact under various wave height, period and over height were simulated. The influences of the three parameters on the distribution of vertical velocities were analyzed, which shows that the distribution rule of the vertical velocities is similar to the wave impact pressures.
