摘要

A method to design a pressure swirl atomizer is presented considering the ideal flow and viscous flow in the form of theoretical and empirical approach and from that the pressure swirl atomizes are designed with spray cone angles of 60°, 90° and 120°. The designed pressure swirl atomizers are experimentally investigated to evaluate the performance parameters like spray cone angle, penetration length and drop diameter distribution at different injection pressures. With the improvement in atomization the cone angle tends to decrease with increase in injection pressure. The penetration length and Sauter mean diameter tends to increase with increase in injection pressure.
