CFD-Based Numerical Simulation for Helical Heating Pipes

Abstract

For helical pipes, author builds their three-dimensional models, identifies their boundary conditions and makes CFD-based simulating calculation for their heat transfer in this paper. Therefore, related theoretical guidance could be made for the design and application of helical heat exchanger by referring to the temperature-distribution and heat-transferring laws elicited from both contrastive analysis and calculation for internal/external flow and temperature distribution in helical heating pipes with different inner diameters and screw pitches.
