A Performance Assessment of a Chemical Based Technology for the Dissub Co2 Removal System in Royal Navy Submarines Using Computational Fluid Dynamic Modelling 2008-01-2130

Having identified a deficiency in the Royal Navy's present DIStressed SUBmarine (DISSUB) Carbon Dioxide (CO2) removal system the Marine Environment Sustainability and Habitability (MESH) Integrated Project Team (IPT) (now Maritime Equipment Transformation (MET)) has run a project to select and install a new CO2 removal system. This uses a chemical based technology in the form of Reactive Polymer Curtains (RPCs) to absorb CO2 from the air.
In order to maximise the potential benefits and better inform the deployment of this product, Frazer-Nash Consultancy has been contracted by MESH IPT to undertake a study using Computational Fluid Dynamics (CFD) to numerically simulate the airflow and CO2 absorption reaction in a realistic survival situation in the forward compartment of a T-Class submarine.
This paper reports the results of an assessment of the proposed deployment strategy for the RPCs based on the CO2 levels throughout the compartment, with particular attention to the CO2 levels around the crew. This will provide an input to the guidelines for deployment of RPCs in survival conditions.
