Local coefficients of heat transfer and local velocity were measured for the case of a heated surface with ribs inclined at an angle of 45o to the flow. The height of ribs was 1.4 % of the hydraulic diameter. The field and profile of non-dimensional coefficient of heat transfer were estimated from thermographic measurements of temperature. The optical method SIV was employed to measure the local velocities at a characteristic distance from the surface. A qualitative correlation between the measured values of heat transfer and velocity was established. Keywords: inclined ribs, heat transfer enhancement, optical measurements, distribution of heat transfer coefficient, velocity field.
