Vertical CO2 Release Experiments from a 1 Liter High Pressure Vessel

High-speed CO2 release experiments from a pressurized vessel have been conducted for a range of storage pressures nozzle diameters. The experiments are conducted to validate and develop models for accidental releases of CO2 during transport. In cooperation with DNV-KEMA lab (Groningen, The Netherlands), medium scale experiments with a 500 liter tank have been designed and performed in spring of 2012. The results of this experiment are reported in a separate GHGT paper by Ahmad et al. [5]. In preparation of these experiments, some optical measurement techniques have been tested in a smaller set-up of a 1 liter vessel, carried out at the TNO Rijswijk facility. These preparatory experiments will be discussed in the current document. A number of optical techniques are evaluated in relation to the observed phenomena. The tested techniques are: HD resolution standard optical camera, HS (high speed) camera and IR (infra-red) camera. In addition some experiments were performed using the PIV (Particle Image Velocimetry) technique, which is reported in a separate paper by de Jong et al. [4].
