N2 - In the present study, an optimal design for enhancement of heat transfer and thermal performance for a stationary channel with angled rib turbulators was investigated to find the most suitable rib geometry. Among various design parameters, two design variables, rib angle of attack (α) and pitch-to-rib height (p/e), were chosen. The ranges of two design variables were set as 30° ≤ α ≤ 80° and 3.0 ≤ p/e ≤ 15.0. Approximations for design of the best rib turbulators were obtained using the advanced response surface method with functional variables. The second-order response surfaces (or correlations) within the ranges of two design variables were completed by this method. As for the optimized results, maximum averaged heat transfer value was obtained at α = 53.31° and p/e = 6.50, while the highest thermal performance value was presented at α = 54.67° and p/e = 6.80.
