Meeting on unsteady friction and other passive causes of damping


On the Friday afternoon after the conference, there will be a specialist meeting on passive causes of damping of pressure surges.  This will be the latest in a series of small international meetings in a series that began in 1993.  Early meetings focussed on unsteady friction and fluid-structure interaction, but the scope now includes other passive causes of damping of pressure fluctuations.  The aim is to increase understanding of the influence of phenomena such as turbulence, visco-elasticity and structural damping on wave propagation.  These phenomena are usually of secondary importance, but they can be of primary importance in particular cases.  The meetings are restricted to causes of attenuation during the propagation of a surge along a pipe.  Forms of surge suppression that depend on interactions between two or more waves – e.g. surge tanks and valve-stroking – are excluded.  They are strongly relevant to the main conference, but they are outside the scope of the specialist meeting.

This meeting is intended exclusively for specialists and participation is by invitation only.  However, new members who could contribute to the advancement of understanding would be warmly welcomed.  There will be no charge for attendance, but advance registration is mandatory and the number of places is limited.

Although closely linked to the technical scope of the conference, the meeting will be organised wholly independently of BHR.  Expressions of interest should be emailed to unfric @ kirkton.net
