The Department has several mobile laser-based measurement systems. They are designed for use on combustion systems outside the laboratory and are deployed for measurement campaigns carried out for customers. Two mobile CARS systems are configured for temperature measurements using the single-pulse technique, in which the air nitrogen present during combustion is used as an indicator. In the case of sooting flames, the modified SV-CARS variant is used. Other mobile systems are available for investigating the structures, stabilisation and blow-out limit of flames, as well as two-dimensional distributions of temperature, species and soot using LIF, Raman and LII techniques. LIF systems with pulse rates greater than 1 kHz are likewise designed as mobile facilities. The following list provides some examples of work carried out in national and international projects and for customers.
