Hussam Jouhara

Hussam Jouhara is a professor of thermal engineering and heat recovery systems at Brunel University of London. He specialises in heat pipe technology and thermal efficiency, and leads the university’s Heat Pipe and Thermal Management Research Group. He is also the founding editor-in-chief of the International Journal of Thermofluids and editor-in-chief of Thermal Science and Engineering Progress.

Career Jouhara obtained his Ph.D. in mechanical engineering from the University of Manchester in 2004. After several years researching at Trinity College Dublin, he joined Brunel University London as a lecturer. In 2011, he left academia to work for the manufacturer Econotherm Ltd, where he developed the manufacturing and design process of various types of heat pipe exchangers as a technical director. In 2014, Jouhara returned to Brunel where he became a senior lecturer and, in 2018, a professor.

Jouhara's research focuses on various thermal management technologies, with an emphasis on developing heat pipe systems. In industry, these heat pipe systems have improved primary energy savings of up to and over 40% in the production of metals, food, and ceramics by recovering waste heat. He has also used them to improve the sustainability of building design, the efficiency of food display cabinets and solar collectors, and the longevity of lithium-ion batteries for electric vehicles, as well as a variety of other applications.

Jouhara has also been involved in several Horizon Europe projects funded by the EU. These include coordinating the GEOFLEXheat project, which aims to improve how geothermal heat is harnessed for industrial applications; iWAYS, which aims to develop a set of technologies that recover water and energy from industrial waste streams; and ETEKINA, which successfully recovered over 40% of waste heat from factories in energy-intensive industries. Jouhara has expressed that his dream is to one day create a 'factory without chimneys' that does not emit toxic or polluting fumes.

Awards In recognition for his contributions to the field of engineering, Jouhara was elected as a fellow of the Royal Academy of Engineering in 2024.

Publications Jouhara is an author of over 200 journal articles and books about thermal engineering, and over 10,300 times according to Scopus.
