About

Overview

Dr Sun joined City in January 2015 as Lecturer in Aeronautics. His research activities are in the area of experimental aerodynamics. His current research is on the Unsteadiness of Transitional Boundary Layer Separation using Tomographic PIV and Infrared Thermography. His other research interests include:
- Flow control
- Turbulence
- Unsteady aerodynamics
- Wind tunnel experiment
- PIV technology

Prior to the present position, he carried out the postdoctoral research in the University of Minnesota since October 2013. His work was mainly in the NSF project of Multi-Scale 3D Observation System for Predator-Prey Interaction.

Dr Sun obtained his PhD degree in the Delft University of Technology in the Netherlands, his PhD research was on the micro ramp vortex generator for supersonic boundary layer control. During his PhD period, he also did a short term visiting research in the University of Texas at Arlington.

Students with strong motivations in Experimental Aerodynamics are welcomed to joined the Experimental Aerodynamics Group in the City University London.

Scholars with PhD degrees are also welcomed to carry out postdoctoral researches. We are happy to host highly motivated scholars!

Please feel free to send out your inquiry to Zhengzhong.Sun@City.ac.uk
