| Abstract: | A numerical simulation was conducted on the base of a three-dimensional model for compact recuperator with offset-strip-fin plate-fin surface. Convection coupled with conduction model was adopted to obtain the temperature and velocity fields in the recuperator with a range of Re=200-2000. Analysis was made for the flow and heat transfer entrance and also the mechanism of enhanced heat transfer for strip-fin plate-fin surface was discussed. The results were compared to references with good consistency. |
