The flow analysis is expected to address the hydraulic issues relevant to the design of CICCs for safe and optimum operation. Flow analysis also yields the pumping power required to circulate the coolant (Supercritical Helium (SHe)). In the present work, a dual channel CICC with central spiral is considered for pressure drop analysis. The effect of mass flow rate on the pressure drop has been investigated. The computational domain is built and meshed in GAMBIT 2.0. The mesh was exported to FLUENT 6.3, a commercial CFD code, for further analysis. It is observed that as the mass flow rate through the conduit increases, the pressure drop increases appreciably. Friction factor in the CICC is calculated from the pressure drop obtained from FLUENT. This paper also presents the CFD methodology to find the pressure drop.
