Professor Ricardo F. Martinez-Botas

Professor in Turbomachinery

Ricardo leads the Turbo Group. He has an MEng (Hons) in Aeronautical Engineering from Imperial College London and obtained a DPhil from St John's College, Oxford University in 1993 with his thesis on “Annular Cascade Aerodynamics and Heat Transfer”.

Research

Ricardo's main area of research is in aerodynamics and heat transfer of turbomachines. The applications relate to aircraft engines, power generation gas turbines, turbochargers and hybrid vehicles. In heat transfer engineering, a significant contribution has been made to the understanding of cooling components, primarily using experimental novel measuring techniques.

He has developed the area of unsteady flow aerodynamics of small turbines, with particular application to the turbocharger industry. The contributions to this area centre on the application of unsteady fluid mechanics, instrumentation development and computational methods. The work has attracted support not only from Government agencies but also from industry. His group has become a recognised centre of turbocharger turbine aerodynamics, and more particularly in the application of experimental methods and one-dimensional calculation procedures.

Dr Teng Cao

Lecturer in Turbomachinery

 

Teng is Lecturer in the Thermofluids Division, Department of Mechanical Engineering, Imperial College London. He obtained his Ph.D. in 2015 at Whittle Laboratory, University of Cambridge. He continued as Research Associate at the Whittle Lab. In 2016, he became MHI Senior Research Fellow and College lecturer at Girton College. He was appointed as Lecturer by Imperial College in September 2021.

Research: Teng’s research has been in the field of turbomachinery which is a crucial component for the current and foreseeable future energy systems in the world. He is passionate about improving the energy system's performance through understanding its aerothermal mechanics using both numerical and experimental methods. Over the years, his work has been devoted to various research areas: (1) Developing high-performance centrifugal compressors, (2) Low-order modelling of Turbomachinery, (3) Fan-intake interactions, and (4) Pulsating flow effects on turbocharger turbine performance. His research outcomes have been largely recognized by peers and published in the world’s premier journals and peer-reviewed conferences. His recent work on centrifugal compressor tip leakage flow instability has been awarded the ‘Turbomachinery Committee Best Paper’ by the American Society of Mechanical Engineering.

Research Staff

Mr Harminder Flora

Research Officer

Harminder joined the Thermal Power research group in the Department of Mechanical Engineering at Imperial College in 1986 under the leadership of the late Professor Neil Watson, who at the time was performing world-leading research into turbochargers. Since then, as Research Officer he has supported numerous turbocharger and automotive powertrain related research projects, including the development of:

  • The Turbo Group's high-speed eddy-current dynamometer, used for turbocharger turbine aerodynamic research and testing
  • Active Control Turbocharger (ACT) technology
  • TASR, the Transient Air System Rig
  • Cavitation in diesel injector nozzles
  • Validation of simulation models for diesel fuel injection systems
  • Apparatus for the measurement of piston ring lubricant films

Harminder’s departmental duties include leading the teaching of CAD on our MEng Mechanical Engineering undergraduate course, co-supervising numeorus undergraduate Design-Make-Test and Final Year Projects, and providing close technical support to PhD research students and Psotdocs in the Thermofluids Division.

Dr Maria Esperanza Barrera-Medrano

Turbomachinery Research Development Manager

Esperanza joined Imperial College London in 2013, as a researcher involved and sponsored by Marie Curie Fellowship program, as part of a project called Energy SmartOps. Afterwards, she did her PhD in Unsteady Flow in Turbocharger Centrifugal Compressors for Automotive applications under the supervision of Prof. Ricardo Martinez-Botas. After completing her PhD, she continued her research on turbocharger compressor performance and efficiency improvement under unsteady conditions within SETTL led by Prof. Ricardo Martinez-Botas and in close collaboration with her industrial sponsor Mitsubishi Heavy Industries, Ltd. She holds two patents related to turbocharger compressor design, as a results of her research.

Research/Role

Esperanza manages international collaborations, design and support the development and completion of technical programs through developing high-quality research proposals and establishing new external collaborations, especially with industry.​She manages the Group’s project’s technical activities, concentrating on the delivery of scientific and application-focused goals, and acts as a regular liaison with the academic and industrial partners.

Dr. Andrew Law

Research Associate

Andrew holds a MEng degree with First Class Honours (2019) from Imperial College London, where he was a Dean’s List student from 2015 to 2019. Hejoined SETTL in 2019 and completed his PhD studies in 2024. He is now working as a postdoctoral research associate.

 

Research

During his PhD, Andrew’s main research focused on assessing system-levelling modelling for hybrid electric vehicles (HEVs), control strategy optimizations, and e-boosting applications in HEVs. He also worked on real-world vehicle emissions data modelling. His postdoctoral work now focuses on multiphase non-ideal compressible flow modelling for carbon capture and storage (CCS) applications and expanding his HEV research into hydrogen fuel cells for light-duty vehicles.
