News

From July 2008 Dr. Markides will be moving to the Department of Chemical Engineering and Chemical Technology at Imperial College London, where he will be taking up the RCUK-Foster Wheeler Fellowship and Lectureship in Clean Energy Processes.


PhD Opportunities

A funded PhD Research Studentship will be available in the study of oscillating transport processes. The position will be available at Imperial College London and will commence in October 2008 (date is flexible). If you are interested please e-mail Dr. C. Markides for more information.


Introduction

Dr. Markides is an Embedded Researcher in the Department of Engineering of the University of Cambridge.
He is in the Energy Group of Division A (Acoustics, Fluid Mechanics, Turbomachinery and Thermodynamics).
He is also an Official Fellow and Engineering Director of Studies of Robinson College, and a Co-founder and Director of Thermofluidics Limited, a Cambridge University Engineering Department spin-off company.
You can view and download his Curriculum Vitae (CV) in Adobe Pdf or Microsoft Word format.


Research

Dr. Markides is interested in the development of technologies that can produce useful work by utilising waste heat or solar energy. He is currently working with Dr. Thomas C.B. Smith and in collaboration with Thermofluidics Ltd. for the development of innovative heat and fluid pumping technologies based on unsteady heat engines called 'thermofluidic oscillators'. A new laboratory of experimental research in this field has been erected in the Hopkinson Laboratory, in the Inglis Building of the Department of Engineering.

Before this Dr. Markides was a Doctoral student and later a Post-doctoral Research Associate (RA) in the Department of Engineering of the University of Cambridge. During this time he set up and performed experiments in a novel apparatus involving the autoignition of simple gaseous fuels in a rudimentary flow geometry, situated in the Hopkinson Laboratory, in the Inglis Building of the Department of Engineering. The aim of his studies were to understand the fundamental science behind the effect of mixing on autoignition chemistry in turbulent flows. He continues to be interested in the investigation of mixing and autoignition in turbulent, non-premixed (inhomogeneous) flows, as well as similar problems encountered in modern combustors or reactors that inhibit their improved performance, i.e. higher efficiency and reduced emissions.


Teaching

Dr. Markides is the Director of Studies for the Engineering Tripos, Part IA, at Robinson College.

Dr. Markides has supervised and/or is currently supervising:

He was voted by the students as Best Engineering Supervisor in the 2006/2007 Robinson College Academic Assessment.

He also demonstrates experiments in the Department, in a wide variety of subjects including coursework on Data Transmission, Spectrum Analysis, Flame Propagation, Stability and Structure, Inviscid Fluid Flow and a number of experiments in the Aerodynamics Laboratory Wind Tunnels. The Flame Propagation experiment demonstrated during 2003/2004 achieved top marks in that year's Departmental Undergraduate Student Survey.
