N2 - The performance of heat transfer in gas-solid fluidization flow is influenced by operational factors, such as gas velocity and temperature. CFD simulation method and Factorial Design of Experiment had been used to investigate in an inferential way, to determine the most significant factor that affects the heat transfer. This research had been conducted with four different superficial velocities of 0.35 m/s, 0.45 m/s, 0.5 m/s, and 0.7 m/s. While the temperature was varied by 150 °C, 200 °C, 250 °C, and 300 °C. The results showed that temperature, velocity, and interaction between velocity and temperature influence the convection heat transfer coefficient. Velocity is the most significant factor because it impacts to bubble formation. However, this study found that there is an alternative way to increase the convection heat transfer coefficient by controlled superficial velocity and temperature.
