Constant volume combustion vessel (CVCV)
Constant Volume Combustion Vessel
Oxford's TPSRG has a long history of laminar burning velocity measurements using a spherically expanding flame in a constant volume vessel. Refined over a number of years and research projects, Oxford's Constant Volume Combustion Vessel (CVCV), euphemistically known in-house as 'the bomb', is housed within a temperature controlled chamber and features bespoke mixture preparation and data acquisition systems. The bomb is fitted with two 40 mm diameter fused silica windows to allow optical access which are typically used with a dedicated Schlieren photography system.
