A comprehensive experiment to measure the wind-induced pressure drag and drag coefficient of a long cylindrical rod was designed.A self-made suction wind tunnel was built,the wind pressure around the rod in a uniform flow field was measured,and the pressure distribution coefficient and the pressure drag were calculated.Based on experimental parameters,Fluent software was used to simulate the wind pressure distribution around the rod.The numerical simulation results are in good agreement with the experimental results,which proved the accuracy of the simulation model.On this basis,the influences of wind speed and rod diameter on the pressure drag of the long cylindrical rod were simulated numerically,and the drag coefficient in the experimental environment was determined.
