FSDL conducted a study on interference effects for inline slender chimneys, commissioned by CICIND, following previous work on the Rugeley chimney. The study, led by Dr. Antolin Lorenzana Ibán, utilized advanced CFD software to validate simulations against real performance data, extending to various wind angles and structures. Design guidance will be provided in a spreadsheet format, with additional research intended for publication in journals and conferences.

Title Interference effects for inline chmineys
Client CICIND
Background Following on from the Rugeley Chimney and TMD monitoring
exercise, FSDL proposed to carry out a study on interference
effect for inline slender chimneys (figure 1). As a result, CICIND
commissioned FSDL to provide design guidance for such
effects using numerical techniques for fluid-structure interaction
based on computational fluid dynamics and validated using
the Rugeley Chimney data.
Response FSDL commissioned a research study managed by Dr Antolin
Lorenzana Ibán using advanced CFD software (Figures 2, 3 &
4). Re-evaluation of the Rugeley Chimney performance data
has validated the simulations, allowing for extension to a range
of different conditions of wind angle and structure
configurations.
Outcomes Design guidance is being produced in the form of a
spreadsheet. In addition, journal and conference publications
are being prepared.
