- •
Velocity profiles obtained by μPIV match the expected velocity profiles.
- •
Double recirculation and bypass flow structures were observed in the wake of the pin fins.
- •
Bypass flow structures are attributed to defects in the mask used for production.
- •
Flow stability has been measured in the flow passages.
- •
Both types of flow structures observed using μPIV were also observed using CFD.
