Thermal Design Recommendations for Subsea Deadlegs: Part Ⅰ. Model Verification and Layout

摘要

This paper presents a CFD investigation of the conjugate heat transferrnin subsea system deadlegs filled with air in a simplified model. Thernsimplified model approach is validated against a complete modelrnanalysis on a deadleg in a full scale test model. The impact of varyingrnthe geometrical layout and horizontal and vertical pipe lengths on thernnature of the convective heat transport is analyzed. Recommendationsrnregarding the CFD evaluation method of deadlegs and deadleg designrnare discussed.
