INTRODUCTION

VKI PhD Symposium

During the sixth PhD symposium, the VKI graduate students will review the doctoral research carried out in the three departments of the Institute: Aeronautics and Aerospace, Environmental and Applied Fluid Dynamics, and Turbomachinery and Propulsion.

The first-year PhD students will present a poster on their research plans and some preliminary results. The second-year students will give a 15-minute talk on their research activities and progress results followed by 5 minutes of questions. The other students will give a 20-minute talk followed by 10 minutes of questions. Prominent lecturers in three application fields of fluid dynamics will give a keynote lecture opening each day of the symposium.

The talks are organized in sessions according to the following topics: "Multiphase Flows," "Uncertainty Quantification," "Aero-Thermal Investigations in Turbomachinery," "Development of Advanced CFD and Optimization," "Noise and Aeroacoustics," "Ablation," "Ground and Flight Experiments," and "Numerical Modeling for Aerothermodynamics."

This year a special IFAR virtual conference (International Forum for Aviation Research http://www.ifar.aero) will be organized in collaboration with NASA. This will be a self-standing session in the VKI PhD symposium on Friday 13 March 2015 between 3:00 PM and 5:00 PM. The goal is to make this virtual conference interactive and the distribution as wide as possible among IFAR members and associated universities. The question-answer session will be accessible from all participating IFAR organizations. Three PhD members have been selected this year to present their work related to IFAR activities: Sara GONZÁLEZ RUIZ, Gabriele GRASSO and Cis DE MAESSCHALCK.
