CFD Simulation of Interference Drag from a T-junction.
Supervisor Dr A Filipone
On a transport aircraft interference drag arises at the junction between the wing and the fuselage, between the fuselage and the tail plane, between the wing and the pylon, etc. In this project it is required to calculate the interference drag created by the junction between two flat surfaces. In particular, it is required to use computational fluid dynamics (CFD) to calculate the junction drag between as a function of the Reynolds number, the intersection angle and the filleting radius.
General Requirements
- Identify suitable experimental data for the validation process.
- Produce a basic CFD model of the intersection and validate against the reference case (point 1).
- Produce a parametric study in terms of Reynolds number, intersection angles and filleting radius.
- Analyse the CFD data to produce a model of the intersection drag that can be expressed by a single equation.
Deliverables
- Selection of experimental data for junction drag.
- Validation of the CFD model against experimental data.
- CFD calculations at the parametric points specified by the project.
- Mathematical analysis of the CFD data.
- Final report that highlights concrete findings and conclusions.
