About Harvey Rosten
Rosten studied Physics at London University (Queen Mary College) and at
Cambridge University (Dept. of Applied and Theoretical Physics). He went
on to complete an M.Phil for work done at the Rutherford Laboratory on the
development of software for the calculation of magnetic fields of large
super-conducting coils of the kind now used in high-energy particle accelerators
From 1974 until 1988 he worked for CHAM Limited as a Project Engineer, Development Manager and finally Company Director. For ten years he was the manager responsible for the development of PHOENICS (the World's first commercial general-purpose CFD sofware), from its conception in 1978 to Version 1.4 in 1988.
Harvey Rosten co-founded Flomerics in 1989 along with Dr. David Tatchell. As Flomerics' Technical Director he was responsible for the core solver development for FLOTHERM, personally writing the solver used in the first version of FLOTHERM.
Recognizing package-level issues as a major bottleneck in the thermal design of electronic systems, he initiated Flomerics' internal Package-Level Thermal Initiative, PLTI, in 1992, which led to Flomerics participation in DELPHI, a major European-funded project to develop thermal characterization methodologies for electronic parts.
his direction, Flomerics' team coordinated the project, which ended in
late 1996. In their final report to the European Commission, the DELPHI
consortium partners concluded that the experimental and model generation
techniques developed in the project could provide a complete methodology
by which reliable thermal of IC packages could be produced.

Unlike the traditional Rja and Rjc parameters, the 'compact' thermal resistance network models developed in the DELPHI project can be used with confidence for a whole range of different operating environments.
This represents a major advance for the whole electronics-thermal community as it allows components to be accurately modelled at board and system level
As a result of these pioneering efforts, and recognising that the full enefit of compact models will be realized when they are routinely provided by the part vendors Harvey sought and obtained funding was provided for a second project, SEED, to promote the creation and use of compact models. As a result of these projects the study of compact models has become a serious effort at universities and research labs throughout the world.
Harvey died of a brain tumor on Monday 23 June 1997. His premature death is a great loss to those who knew him and worked with him, and to the whole of the electronics cooling community. Harvey's deep understanding of Computational Fluid Dynamics (CFD) and physics, along with his practical hands-on approach made him a true pioneer in the field of thermal analysis of electronic systems.
Harvey was postumously awarded the 1998 IEEE SEMI-THERM THERMI Award, which was accepted by his long-time friend and colleague David Tatchell, CEO of Flomerics.
