文摘

Local heat transfer downstream a single pin fin in a microchannel was experimentally studied. The interaction between the flow structure and the local heat transfer was revealed. An interplay of fluid convection and solid substrate conduction was discovered and explained. Numerical simulation was used to resolve the local heat transfer coefficient.
