  Biography
  Professor Martinez-Botas is acknowledged as a world leading expert in aerodynamics and heat transfer of turbomachines. In his 12 years at Imperial College London, he has led his team to outstanding achievements in turbine unsteady aerodynamics, flow control and waste heat recovery technologies. He is the Professor of Turbomachinery in Mechanical Engineering Department, the head of Thermofluid Division and Theme leader of Electric and Hybrid Vehicles within the Energy Futures Lab Institute at Imperial College London. He is a member of the Science Advisory Council of the UK Department for Transport and the Vice-Chair of UnICEG (University Internal Combustion Engines Group, UK). He is also the visiting professor in several Universities (NTU, UTM) and member in famous academic organizations.
 
  Abstract
  The industry of Internal Combustion Engine is geared to Engine Downsizing for energy conservation and CO2 reduction. Turbocharging is the key enabler for the Engine Downsizing. As the boundaries of the technology is pushed forward, several challenges, including turbine performance degradation under pulsating conditions, waste heat recovery from low pressure gas, are under extensive investigations. The recent research activities in Imperial College London and the outlook of future on those challenges will be shared and discussed in details in the lecture.
