This report deals with the experimental study which focused on the relationship between the local heat transfer coefficient of ribbed surfaces and the heat flux ratio (the ratio of heat flux on the ribbed surface to the one on the base surface). Experiments were carried out with a parallel channel with a ribbed lower surface and a smooth upper surface. Square bars were attached to the lower surface. Heat flux ratio ranged from 0.5 to 2.5, Reynolds number from 3×10^3-1×10^5, the ratio of pitch to the height of the rib from 2.5 to 60 and the ratio of the height of rib to the hydraulic diameter of the parallel channel from 0.032 4 to 0.174.
