Heat Transfer and Fluid Mechanics
Dr. Worek has been involved, over the last 35 years, in the development of desiccant materials for cooling systems applications, modeling of sorption processes, experimental testing of desiccant material performance and the use of desiccant processes in the design of cooling and dehumidification systems. He holds three patents on sorption system design improvements and has published extensively in archival journals and has given numerous lectures on the subject. Also, he has investigated heat transfer enhancements to when nanofluids are boiled. Dr. Worek was chair of the American Society of Mechanical Engineer’s (ASME’s) Solar Energy Division, Vice-President of ASME’s Energy Resources Group and served as a Member of ASME’s Board of Governors. Dr. Worek is Fellow of ASME, Life Fellow of the American Society of Heating Refrigerating and Air-Conditioning Engineers (ASHRAE). He has received Edwin F. Church Medal from ASME recognizing his accomplishments in engineering education and the Frank Kreith Energy Award. In addition, Professor Worek Co-editor of new 12thEdition of Mark’s Standard Handbook for Mechanical Engineers, Executive Editor of Applied Thermal Engineering, Editor-in-Chief of The International Communications in Heat and Mass Transfer and Heat Transfer – Asian Research. Dr. Worek has consulted worldwide. He was Chair, Mechanical and Systems Engineering Board of the Research Grants Council (RGC) of the University Grants Committee (UGC) of Hong Kong and currently serves the University Grants Committee (UGC), Panel Member and Project Monitor of the Collaborative Research Fund (CRF), the Theme-based Research Scheme (TRS) and the Areas of Excellence (AoE) Funding Schemes Projects.
