Research interests

In general, I have conducted research on various aspects of power generation, renewable energy, and solar air conditioning. As a result, I have acquired several skills and tools for analyzing a power generation cycle including energy, exergy, and economic analyses and optimizations. Additionally, I have worked with different solar collectors such as parabolic troughs, heliostat field collectors, and photovoltaic/thermal collectors (PV/T). Moreover, I have experience in both solar power generation and solar air conditioning. My research interests are, among others, in concentrated solar power, Photovoltaic/Thermal, gas turbine inlet cooling, power generation, thermal energy storage, solar power generation, solar air conditioning, desiccant-based air conditioning, solar fuel and hydrogen production, carbon capture and storage.

Biography

Mohammad Saghafifar is currently a PhD student in the Engineering department of the University of Cambridge. He is working under the supervision of Dr. Stuart Scott. He holds M.Sc. and B.Sc. in Mechanical Engineering from American University of Sharjah. For his Master studies, he investigated the feasibility of a 50 MWe solar hybrid combined cycle power plant with a topping gas turbine cycle and four different bottoming cycles. Power plant hybridization was accomplished by employing solar tower collector (Heliostat field collector). Three rather unconventional bottoming cycle configurations were chosen including gas turbine (air bottoming cycle), water injected gas turbine (water injected air bottoming cycle) , and the Maisotsenko cycle (Maisotsenko bottoming cycle). These three configurations along with the conventional combined power plant (steam bottoming cycle) were optimized by conducting thermo-economic and transient analyses in MATLAB to identify the most economically justified plant configuration for the UAE.
