Two multi-objective optimization designs of the rotor blade for an axial transonic compressor
are carried out in this study. Among them, the optimization of the blade alone is called blade …

As a core component of a fan, the blade has a decisive impact on the aerodynamic
performance of a low-pressure axial flow fan. Due to the limitations of the classical fan …

Axial fans with a small hub-to-tip diameter ratio are used in many branches of industry.
Optimization of their aerodynamic performance is important, for which using sweep …

The shape of the blade stacking line greatly influences the low-pressure axial-flow fan's
operational efficiency, but there is still no fast and effective way to determine the stacking …

Large air-cooled heat exchangers are used to cool process fluids in thermodynamic cycles
in a range of industrial processes. These systems consume less water than wet-cooled …

Common blade design techniques are based on the assumption of the airflow laying on
cylindrical surfaces. This behaviour is proper only for free-vortex flow, whereas radial fluid …

Forward swept blades in low-speed axial fan rotors allow for appreciable gain in the stall
margin and a small percentage gain in the maximum fan efficiency if the rotor blade …

叶片弦向弯掠技术是提升轴流风机气动性能的有效手段. 针对带后置导叶的OB-84
型单级动叶可调轴流风机, 利用Ansys 数值软件, 对比叶片掠设计前后风机的性能曲线和内流 …

The flow path close to the suction side of fan rotor blades mostly affects the overall drag of
the blading. The blade lift is affected as well because of the separation of the low energy …

Numerical algorithms for the flow of cooling tower axial fans in the flow wise direction and
span-wise direction have been transformed and solved by the Matlab application with a …
