Abstract

To master internal performance and design method of 2D-CD nozzle,the internal performance of 2D-CD nozzle was investigated by numerical simulation method.The influence of circular-to-rectangular transition duct outlet area to inlet area ratio and circular-to-rectangular transition duct length on the internal performance of 2D-CD nozzle were analyzed.The results show that a small change in internal performance happens as circular-to-rectangular transition duct outlet area to intlet area ratio decreases.Because a smaller outlet area needs a shorter convergent flap length,thus the nozzle design can be optimized in length and weight aspect.And as the circular-to-rectangular transition duct length decreases,only a little loss in internal performance is obtained.Thus the whole length and weight of nozzle can be optimized at the cost of a little loss in internal performance.
