Abstract
Pressure drag is a mechanical force generated by a solid moving object in fluid. This project focuses on the reduction of pressure drag in aircraft. Pressure drag is an unavoidable force which forms as a reaction force to the motion of the aircraft and thereby decreasing its performance. So, the object must put forth a huge extra force to pass through, likewise the aircraft needs more power to overcome the pressure dragforce which leads to more fuel consumption and decreasing the aircraft’s efficiency. The complete aim of the project is to add a pressure drag reducing agent called vortex generator to reduce the pressure drag and increase the performance and efficiency of the aircraft. The addition of vortex generators will reduce the pressure on the wings surface which leads to rise in velocity on the wings surface. The increase in velocity anddecrease in pressure will decrease the pressure drag force that acts on the aircraft which thereby increases theaircraft’s performance. This project holds the complete process of modeling aircraft in CATIATM V5 and analyzing the aircraft with vortex generators to clearly visualize the idea of using vortex generators to reduce pressure drag. As computational fluid dynamics analysis using ANSYS® FLUENT can easily compute resultson applications that use airflow, it is used for analyzing the aircraft’s wing to show the reduction of pressure drag
