Dr. Ahmad Abbas

Brief

Ahmad Abbas holds BSc in Mechanical Engineering from University of Engineering and Technology, Peshawar, and MS and PhD in Mechanical Engineering from GIK Institute of Engineering, Sciences and Technology. His PhD work was a pioneering in the area of direct expansion where for the first time dry expansion evaporation characteristics of natural refrigerant (Ammonia) was experimentally studied.

His research interest includes experimental thermo-fluids, Enhanced heat transfer, Low charge industrial refrigeration systems and technologies, HVAC systems, Computational mechanics and Autonomous navigating mobile robots. He is interested in teaching Thermodynamics, Fluid mechanics, Heat transfer, Power plants, Refrigeration and Air conditioning and Instrumentation and measurements at undergraduate level.
