Icing Problems in The Aircraft Engine’s Intakes

This study contains five chapters as follows:Chapter (1): Contains an introduction on the problem of ice accretion due to super-cooled water DROPlets impingements on the aerodynamic surfaces and its effects on the aircrafts.Chapter (2): Contains a literature review a bout the air flow deterioration on airfoils due to ice accretion, predicting ice shapes by using computer codes, intakes aerodynamics and the other variables that arises due to ice accretion that affect the airflow.Chapter (3): In this chapter the air flow around and through the intake is studied. The air flow results are discussed as well.Chapter (4): Contains the study of the behavior of the water DROPlets trajectories. The DROPlets trajectories, DROPlets impingement locations is predicted. The effect of the DROPlet size on the trajectory, the impact locations, and the predicted ice accretion thicknesses are discussed.Chapter (5): In this chapter, the effect of accretion on the intake performance deterioration is discussed.Chapter (6): Contains the thesis conclusion and the future studies..
