概要

• 論文の詳細を見る

• In order to reduce the loss of flow in the conical diffusers of large diverging angles, boundary layer suction through a single slit at the entrance is examined. Experiments are carried out for conical diffusers having area ratio of 4 and diverging angles of 10〜60 degrees. The loss coefficient decreases to the value of 0.2 for all angles of divergence, when the rate of suction quantity is 2%. Theory for the optimum rate of suction is discussed. A method to find out the separation point by powder is also examined.
