In the present article AHP, entropy, and TOPSIS techniques are applied to select the optimal performance parameters of alumina/water nanofluid flow in protrusion ribbed square channel. AHP and entropy method is used to determine the subjective, objective, and synthesis weights of all three PDAs which are \( Nu_{\text{ave}} \), \( {\text{f}}_{\text{ave}} \), and \( \eta_{p} \) respectively. TOPSIS technique is used to find relative closeness index and to rank all the alternatives which offer the optimal alternative. The alternatives with a maximum value of closeness index are nominated as an optimal alternative. From the results, alternative order based on relative closeness index is A15 > A16 > A14 > A7 > A11 > A8 > A6 > A12 > A9 > A13 > A10 > A5 > A4 > A3 > A2 > A1. The alternative A15 having maximum value 0.8459 of closeness index exhibits optimal performance.
