Mohammad Jahedi investigates the fluid mechanics and heat transfer of a range of cooling technologies using computational and experimental approaches, leading to applications in industrial cooling processes and the design of more efficient and sustainable systems.
“My main focus has been on development of quenching hardening process in recent years both numerically and experimentally. Development of an inverse solution into this application to predict the surface heat transfer data during quenching process. This provides key information about the cooling techniques characteristics. Moreover, two unique and modern test facilities have been built up in the Metal Cooling R&D Living Lab at University of Gävle to investigate the heat transfer characteristics of cooling processes. The main aim of the living lab is to create a long term platform that supports companies in the development of new materials and cooling processes, and to support the formation of new companies based on the new technologies for cooling of metals. The Living lab has been equipped with advance physical test facilities for carrying out hardening cooling experiment, resources for computer simulation, as well as resources for materials testing.”
Current research activities:
This project focuses on development of the impinging jet technology for cooling of metals from high temperatures. The technology makes it possible to create cooling processes that give the steel improved performance in several respects:
The project aim is to reveal the spatial-temporal behavior of a newly developed cooling technology in order to produce steel bars with excellent properties and to control the phase transformation and residual stresses to achieve optimal performance of the steel bars depending on the application.
