The Universities of Cambridge, Ghent, Rouen, Delft and Darmstadt are member of SIG28.

Objectives:
The aim of this workshop series is to stimulate progress in the understanding of turbulent spray combustion by organizing focused discussions on open problems and promising new initiatives and collaborations in this area. A long term objective is to advance capabilities to model turbulent spray flows, both reacting and non-reacting. In order to do so it links recent developments in studies of dispersed multiphase flow and combustion. The intention is to have interactive discussion between experts and young researchers and between modelers and experimentalists.

The 8^th workshop will focus on spray atomization. Currently the absence of accurate measurements and predictive models for atomization forms a bottleneck for accurate description and prediction of turbulent spray flames. Better understanding of primary and secondary atomization is needed to eliminate limited knowledge of initial spray characteristics. New experimental techniques and modeling techniques are being developed make progress in understanding how atomization influences both the dense spray region and the dilute region. They will be reviewed and discussed at the workshop. Benchmarking computational models of complete spray flames exploiting detailed experimental datasets remains in place. This is the day preceding the 12th Mediterranean Combustion Symposium.

Program:

In order to reach the objectives a program is set up with the following elements:

• Two keynote speakers, one more research oriented and one more application oriented (from industry)
• Discussion of joint comparative studies of numerical simulations of a number of target test cases for which extensive experimental databases are available
• Poster session enabling all participants to show their work in progress
• Discussion sessions to identify essential topics needing further investigation

Databases and proceedings:
In preparation of the workshop a special effort is made to collect and compile the best possible experimental datasets useful for model validation. The databases remain available for use afterwards and in a number of cases are suitable for inclusion in the ERCOFTAC wiki.

The proceedings reporting on results of this and previous workshops will be published as a special issue in Flow, Turbulence and Combustion (to be discussed with the editors).

Accommodation:

Reservation and payment of accommodation in the hotel must be reserved through the MCS12 website: https://mcsymposium.com. It should be indicated that you are a TCS workshop participant in the following way:

• if you are not attending MCS12: just add in the field ‘full name’ the text “(TCS participant)”, e.g. “John Smith (TCS participant)”
• if you are attending MCS12 without paper or WIP: just insert in the field ‘paper’ the text “(TCS participant)”
• if you are a regular MCS12 participant: just add “and TCS” in the field of paper/WIPP; e.g. “MCS12-100-TC and TCS”.
