考虑铺层的复合材料螺旋桨流固耦合计算及验证

摘要

In order to verify the correctness of the composite propeller's fluid-structure interaction computation algorithm , the fluid model and structural model were established to carry out stable two-way fluid-structure interaction calculation in Ansys/CFX.The target composite propeller has symmetric glass fiber strengthen layers whose fiber orientation angles are ±45°.By iter-ative calculation, the open-water performances of target propeller at different J were gotten .The open-water experiment on the tar-get propeller has been done .The experimental datum agree well with the predicted results , both meet the requirements of engi-neering application .It also proved the correctness of the two-way fluid-structure interaction algorithm based on Ansys/CFX.%为了验证考虑铺层的复合材料螺旋桨流固耦合算法的正确性，利用ANSYS/CFX软件，对±45°对称铺层的玻璃纤维增强材料螺旋桨建立流体模型和结构模型，实现双向流固耦合稳态求解，得到不同进速系数下的敞水性能，模型桨敞水试验结果表明，数值计算与试验吻合良好，均满足工程应用的要求，验证了采用ANSYS/CFX双向流固耦合算法计算复合材料螺旋桨的正确性。
