Rotor spinning is known for high production rates and uniformity of the resulting yarn. However, determining machine components which will produce the optimum process parameters such as airflow speed to result in the best combinations of yarn quality and uniformity can be a difficult task. The aim of this study is to simulate and analyze the airflow characteristics in rotors with U and V grooves during the rotor spinning process. The results obtained showed that airflow speed resulting from a rotor with the V groove is higher than that of U type. As a result, the static pressure resulting from the use of the V type groove is lower than that of U groove.
