摘要
利用计算流体力学(CFD)技术数值模拟了TY7.7—25离心通风机内部的压力场和速度场,分析了离心风机内流场的压力、速度等参数的分布,并按国家标准GBl236-85对风机的性能进行了测定,结果表明TY7.7—25型风机具有压力高、风量大的特点.
Numerical simulation was presented to investigate the flow field inside the centrifugal fan with the type of TY 7.7-25No8.0, and the performance of the fan was also tested. The result of numerical simulation agrees well with the testing data, both the numerical and the testing result indicate that the fan has higher pressure and more flow rate than others.
