This paper describes the experimental investigation and Computational Fluid Dynamics (CFD) simulations of the dispersion of CO2 following high-pressure dense phase CO2 pipeline failure. A full-scale burst test was carried out to simulate a CO2 pipeline failure in the real world. The atmospheric dispersion of the CO2 following the explosive release was measured. The CFD models were validated against the experimental data. The models were then used to estimate the consequence distances related to CO2 dispersion following failure of pipelines with various diameters under different wind speeds. This approach provides a predictive formula for the consequence distances of CO2 transmission …

CO2 heat pumps have drawn a great deal of attention owing to their advantages of high efficiency and environmental friendly for heating water under low ambient temperature. However, the system performance is not desirable and shows a lower COP for space heating, especially for a radiator as heating terminal, due to the higher inlet water temperature at the gas cooler, which causes a large throttle loss when the refrigerant flow through the throttling device. To tackle this issue, a transcritical CO2 heat pump system integrated with thermal energy storage (TES) systems was developed in this paper. The heating performance of …

Liquid CO 2 blasting of coal or rock body technology is widely used for improving permeability, pressure relief, cutting proof, and roadway development. Due to the lack of proper apparatus for blasting measurement, the determination of blasting parameters is often not under scientific basis. A newly designed experimental apparatus is developed to monitor shock-wave pressure of liquid CO 2 blasting. The apparatus mainly consists of testing tube and base bracket. The testing tube is fixed on the base bracket by fixed ring. The base bracket is fixed to the ground by expansion bolts to ensure the stability of the apparatus …
