A numerical study of flow structure and heat transfer in a square channel with ribs combined downstream half-size or same-size ribs
The present study employs square cross-section ribbed channels with different arrangements of downstream half-size ribs to determine the most optimal configurations for augmenting heat transfer rates with minimized pressure drop penalties. The channel inlet Reynolds number ranges from 20,000 to 160,000. The influence of downstream ribs arrangement on the overall performance characteristics of ribb
