PrefaceThis special issue of the IJHFF is dedicated to our colleagues andfriends Brian Launder and Kemal (Kemo) Hanjalic, following their
75th birthdays in 2014, to celebrate their extensive contributionsin the area of turbulent ﬂow and heat transfer dynamics.

Brian received his undergraduate training at Imperial College
where he received a B. Sc (Eng) degree in Mechanical Engineering.
He then pursued his graduate education while at the Gas Turbine
Laboratory at MIT where he was awarded both his M.S. (1963)and D.Sc. (1965) degrees in Mechanical Engineering. Upon returning to the U.K., Brian began his academic career at Imperial Collegein 1964 as a Lecturer. This was followed in 1971 by promotion toReader in Fluid Mechanics for his early research on turbulencemodelling. In 1976 he accepted an invitation from the Universityof California, Davis to join the faculty as a full professor. After a stayof four years, he returned to the UK to head the MechanicalEngineering Department’s Thermo-Fluids Division at UMIST inManchester. He led the Division for more than ﬁfteen years andserved two terms as Head of Department. In 1998 he wasappointed the inaugural chairman of UMIST’s Environmental
Strategy Group to promote the development of a coordinated programme of research and teaching on the environment while from2000 he served six years as Regional Director of the Tyndall Centrefor Climate-Change Research.
Brian has been a major contributor to the development ofmathematical models of turbulence and their application to a wide
range of complex industrially important ﬂows, particularly hotsection components of gas turbines. Over his career he supervised
more than 40 doctoral students and published more than 300 technical articles as well as (co)-authoring 4 books. He was elected a

Fellow of both the Royal Society and the Royal Academy of Engineering in 1994 for his contributions to the modelling, measurement and computation of turbulent ﬂows. Other awards haveincluded higher and honorary doctorates from seven international
academic institutions and the quadrennial Nusselt-Reynolds Prizein Fluid Mechanics. He was appointed an Editor-in-Chief of theInternational Journal of Heat and Fluid Flow in 1987, a role he discharged for 25 years. Thereafter he continued as an Editor-at-Large
handling special issues for two years.
Kemo received his Dipl. Ing. from the University of Sarajevo inMechanical Engineering – Energy Engineering in 1964. His graduate education followed in the U.K. where, in 1966, he received
his M.Sc. in Thermodynamics and Related Studies from the University of Birmingham, and in 1970 his Ph.D. from Imperial College in
Fluid Mechanics. During this period in the U.K., Kemo held theposition of Lecturer at the University of Sarajevo. After receiving
his doctorate, he was promoted to Docent, Associate Professor in
the Faculty of Mechanical Engineering and in 1979 to the positionof Professor of Fluid Mechanics and Turbomachinery. During histenure at the University, he also held various administrative positions including Head of Department of Mechanical Engineering and
Dean of the Faculty of Mechanical Engineering as well as the Director of the Institute for Process-Power and Environmental Engineering. Noteworthy during this period were his service as mayor ofSarajevo and cabinet member in the government of Bosnia andHerzegovina. In 1991 he left Sarajevo and was Guest Professor ofthe German Research Association at the University of Erlangenuntil 1993. After having spent one year in the United States as
Professor of Mechanical Engineering at Michigan TechnologicalUniversity, he joined TU Delft as the Professor and Head of theThermoﬂuids Section in 1994, a position he held until April,
2005. After retirement from Delft, his pace of activity and productivity continued, and throughout the last decade he has heldpositions at TU Darmstadt (2005–2007) and the University ofRome ‘‘Sapienza’’ (2007–2010) where he held a (EU) Marie Curie
Chair in Computer Modelling and Simulation of Fluids and ThermalProcesses. From 2011, he has been Lead Scientist at the Novosibirsk
State University.
Kemo has also been a major contributor to the development ofmathematical models of turbulence, and has published extensively
on topics of heat transfer, combustion and MHD. In addition tosupervising 30 doctoral students, he has (co)-authored 4 books,
edited 12 volumes, and has received 2 patents (detonation wave
technique for deposit removal). Kemo holds a D.Sc. from theUniversity of London (UK) and a Dr.h.c. from the University ofReims (Fr). He is a Member of the Academy of Sciences and Artsof Bosnia and Herzegovina, and an International Fellow of theRoyal Academy of Engineering (FREng) in the UK. He was2

appointed in 2005, and continues to serve, as the Editor-in-Chief ofthe journal Flow, Turbulence and Combustion.
For almost two generations of professional activity that
included educating and training students, collaborating with colleagues and extensively contributing to the advancement ofknowledge in ﬂuid ﬂow dynamics and heat transfer, both Brianand Kemo have set a standard of excellence for the community.
They have co-authored two of the most cited articles that haveappeared in the area of turbulent ﬂow modeling. The ﬁrst was on
high-Reynolds number Reynolds stress modeling (JFM, vol. 52,pp. 609–638, 1972) and the second on low-Reynolds number Reynolds stress modeling (JFM, vol. 74, pp. 593–610, 1976). Morerecently, they have jointly authored the textbook Modelling Turbulence in Engineering and the Environment, CUP 2011.

It has been our distinct honor and pleasure to have had theopportunity to edit this celebratory volume of IJHFF. We are grateful to the contributing authors for their contributions and want tothank them for their cooperation throughout the editorial process.
This volume is but a small token of our appreciation to Brian andKemo for their numerous contributions and we look forward to
many more years of activity from them.
