ABSTRACT Free convection and entropy generation inside a complex annular pipe were vital for different applied thermal engineering systems. The current study investigated the flow characteristics porous Cassini oval pipe, considering response surface methodology (RSM) joint with CFD. multi‐objective optimum design was novel consideration to improve heat transfer in terms of Nusselt number ( Nu m R ) rate QR reduction EnR frictional losses SFCR under parameters, such as aspect ratio (0.08 ≤ AR 0.2), angular rotation (0° θ 90°), porosity (0.15 ɛ 0.95), pore per inch (10 PPI 30). main data indicate that aim is achieved enhancement by nearly 23.78 times SCFR approximately 91.45% appropriate about 1.0227 times. This demonstrate resilience design's hydrothermal performance operation temperatures ΔT Thus, optimization function useful proposed process optimizing several parameters.
