Dr. Wakil is working on thermal systems for cooling and desalination and their hybridization (Multi-effect Desalination, Absorption Chiller, Adsorption Chiller and Desiccant Dehumidifier) for overall system performance improvements. He is also working on heat transfer improvement specially for falling film evaporators at low temperature operation (<50C). He developed a correlation for falling film heat transfer coefficient. He is also working on economic analysis of single and hybrid systems. He developed a model for primary fuel cost apportionment in dual-purpose plants based on exergy analysis. He is also involves, system design, P & ID and P & FD development, system installation and its integration. He also has expertise on complex system modelling and simulation.
