Urban fluid mechanics: current issues and trends-summary of the special symposium on urban fluid mechanics at the ASME 2014 4th joint US-European fluid engineering division summer meeting.

As part of ASME 4th joint US-European Fluid Engineering Division Summer Meeting, which took place in Chicago in August 2014, a symposium was held on Urban Fluid Mechanics, spanning from urban issues such as climate and heat island effect, to small city-scale effects, such as the flow around isolated buildings. The aim of the present note is to make a synthesis of the presentations, in order to highlight current trends of research and issues. [ABSTRACT FROM AUTHOR]
