Abstract:

Abstract:To study steel structure small machine indirect cooling tower resistance character, a power plant’ 600MW direct cooling unit was taken as study object. Using ICEM-CFD and Meshing software to complete the grid division, the use of Fluent software to calculate the model throughout the flow characteristics, by using fluid mechanics formula modeling, resistance factor was calculated by ANSYS. The result indicated that throat position has largest negative pressure and largest air flow. Resistance factor at X column is smaller than at tower body. Bending position has largest resistance factor. Resistance factor at tower body decreases with Reynolds Number increases.
