چکیده
|
Squirrel cage fans are commonly used in hvac (heating, ventilation, and air conditioning) systems. the single arc blade model is commonly used in this type of fans since it can be shaped simply only by two parameters of inlet and outlet angle of blade. however, the efficiency of the fans is much lower than that we expected. in this paper, the single arc blade is replaced by double-arc blade in order to optimize the blade model and to improve the static pressure efficiency and total pressure efficiency of the fan. numerical results show that the design with double arc blade is able to improve the internal flow, and to enhance the aerodynamic performance of squirrel cage fans.
